viii BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide

Chapter 1. General information

The IBM®BladeCenter E Type 8677 and 1881 unit is a high-density, high-performance rack-mounted system developed for medium-to-large businesses. It supports up to 14 blade servers, making it ideally suited for networking environments that require a large number of high-performance servers in a small amount of space. The BladeCenter system provides common resources that are shared by the blade servers, such as power, cooling, system management, network connections, and input/output (I/O) ports (diskette drive, optical drive, ports for USB, keyboard, video, mouse, and network interfaces). The use of common resources enables small blade server size, minimizes the cabling required in a working configuration, and eliminates resources sitting idle.

Performance, ease of use, reliability, and expansion capabilities were key considerations during the design of your BladeCenter system. These design features make it possible for you to customize the system hardware to meet your needs today, while providing flexible expansion capabilities for the future.

Notes:

1. Current BladeCenter E models do not have a diskette drive in the media tray.

Older BladeCenter E models do have a diskette drive in the media tray. In this document, this difference is noted, when necessary, to describe differences that exist between current and older model offerings.

2. The illustrations in this document might differ slightly from your actual hardware:

the illustrations do not depict a particular model offering unless noted in text.

3. Throughout this document, the terms I/O module and switch module are used to

refer to switch modules and all other types of I/O module.

Information

System error

Attention: If the power-on LED is off, it does not mean there is no electrical current present in the BladeCenter unit. The LED might be burned out. To remove all electrical current from the BladeCenter unit, you must unplug all power cords from all power modules.

Note: You can turn off the location LED and the information LED through the Web interface or the IBM Director console.

Power-on: When this green LED is lit, power is present in the BladeCenter unit. When this LED is off, the power subsystem, the ac power, or the LED has failed, or the management module is not present or not functioning.

Location: When this blue LED is lit or flashing, it has been turned on by the system administrator to aid in visually locating the BladeCenter unit. If a blade server requires attention, the location LED on the blade server usually will also be lit. After the BladeCenter unit has been located, you can have the system administrator turn off the location LED.

Over-temperature: When this amber LED is lit, the temperature in the BladeCenter unit exceeds the temperature limits, or a blade server has reported an over-temperature condition. The BladeCenter unit might have already taken corrective action, such as increasing the blower speed. This LED turns off automatically when there is no longer an over-temperature condition.

Information: When this amber LED is lit, a noncritical event has occurred that requires attention, such as the wrong I/O module inserted in a bay or power demands that exceed the capacity of power modules currently installed. The event is recorded in the event log. Check the LEDs on the BladeCenter unit and the blade servers to isolate the component. After the situation is handled, have the system administrator turn off the information LED.

Note: The information LED will also light if the system error log is 75% full. System-error: When this amber LED is lit, it indicates that a system error has

occurred, such as a failed module or a system error in a blade server. An LED on one of the components or on a blade server is also lit to further isolate the error. (For more information, see “Identifying problems using the Light Path Diagnostics feature” on page 29.)

Setting up the BladeCenter unit

This section briefly discusses considerations for the setup of your BladeCenter unit. v Blade bays must be occupied at all times.

To help ensure proper cooling, performance, and system reliability, make sure that each of the blade bays on the front of the BladeCenter unit has a blade server, expansion unit, or filler blade installed.

Important: When replacing a blade server or installing an expansion option, do not operate the BladeCenter unit for more than one minute without either a blade server, an expansion option, or a filler blade installed in each blade bay.

Chapter 1. General information 17

v Module bays must be occupied at all times.

To help ensure proper cooling, performance, and system reliability, make sure that each of the module bays on the rear of the BladeCenter unit has a module or filler module installed.

Important: When replacing a module, do not operate the BladeCenter unit for more than one minute without either a module or a filler module installed in each module bay.

v There is no power switch on the BladeCenter unit.

The BladeCenter unit does not have a power switch. Plugging the power cords into the power modules and a 220 V ac power source (rack-mounted 220-volt PDU) starts the BladeCenter unit (the management module, I/O modules, and blowers start running).

Each blade server in the BladeCenter unit has an individual power-control button behind the control-panel door on the blade front that turns on or turns off the blade server. Be sure to shut down the operating system before turning off the blade server, to avoid damaging the hard disk drives.

Notes:

1. The blade server power button turns on or turns off the blade server if local power control has not been disabled through the management module.

2. The blade server power button turns on the blade server only if the green power light on the blade server is flashing slowly. If the light flashes rapidly, the blade server has not yet synchronized with the management module, and the power button will have no effect.

See the IBM BladeCenter Type 8677 Installation and User’s Guide for more information about the BladeCenter unit. See the Installation and User’s Guide for your blade server for more information about the blade server power controls and turning on or turning off the blade server.

v The removable media drives are detected as a Universal Serial Bus (USB)

device The removable media drives in the BladeCenter unit are viewed as a USB

devices by the operating system in the blade server. Make sure that your operating system provides USB support.

v Hot-swap capabilities

The front bays on the BladeCenter unit are hot-swap blade bays; the rear bays on the BladeCenter unit are hot-swap module bays. You can add, remove, or replace blade servers or management, I/O, power, or blower modules in hot-swap bays without removing power from the BladeCenter unit.

Attention: To maintain proper system cooling, each unoccupied bay must contain a filler blade and an expansion or filler module. When replacing a blade server or installing an expansion option, do not operate the BladeCenter unit for more than one minute without either a blade server, an expansion option, or a filler blade installed in each blade bay or without a module or filler installed in each rear bay.

18 BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide

Connecting to the default IP address on a new BladeCenter

A newly-installed (out-of-the-box) BladeCenter unit tries to locate a DHCP server on the network before it will default to the factory-configured static IP address in the management module. This is the initial configuration setting. When there is no DHCP server on the network the BladeCenter unit is connected to, it can take several minutes before the management module uses the default (static) IP address. When the DHCP search times out and the management module uses the static IP address, you can change the management module configuration so that it will not attempt to locate a DHCP server.

See the Installation Guide and User's Guide or Command-Line Interface Reference Guide for your management module type for information about connecting to and configuring the BladeCenter management module.

Registering and profiling the BladeCenter products

You can register and profile the BladeCenter unit and blade servers on the World Wide Web.

v To register, go to: http://www.ibm.com/support/mysupport/ v To profile, go to: http://www.ibm.com/systems/support/

Important:

1. Do not switch control of a shared removable media drive to another blade server until the activity lights on the drive is off, indicating that no read or write operations are in progress. Before you remove a hot-swap blade server from the BladeCenter unit, you must shut down the operating system and turn off the blade server. You do not have to shut down the BladeCenter unit itself.

2. It can take approximately 20 seconds for the operating system in the switched-to blade server to recognize the removable media drives and USB port or the keyboard, video, and mouse.

a. The system-error LED might light, and a KVM allocation error might be

logged if the change in ownership for the removable media drives and USB port or the keyboard, video, and mouse takes more than 8 seconds. The system-error LED will go off after the ownership change is complete.

b. It can take up to 48 seconds after a blade server is initially turned on before

you can attempt to switch KVM control to that blade server.

Chapter 2. Configuring your BladeCenter unit

The BladeCenter unit automatically detects the modules and blade servers that are installed and stores the vital product data (VPD) information. When the BladeCenter unit is started, it automatically configures the remote-management port on the management module, so that you can configure and manage the BladeCenter unit and blade servers. You configure and manage the BladeCenter unit remotely through the management module using the Web-based user interface.

Note: You can also configure the I/O modules directly through an external I/O-module port using a Telnet interface or a Web browser. See the documentation that comes with the I/O module for more information.

For the management module to communicate with the blade servers in the BladeCenter unit, you will need to configure the IP addresses for the following internal and external ports:

v The external Ethernet (remote management) port on the management module

(see the User's Guide or Command-Line Interface Reference Guide for your management module type for instructions). The initial management-module autoconfiguration enables the network-management station to connect to the management module to configure the port completely and to configure the rest of the BladeCenter unit.

v The internal Ethernet port on the management module for communication with

the I/O modules (see the User's Guide or Command-Line Interface Reference Guide for your management module type for instructions).

v The internal Ethernet management port on each I/O module for communication

with the management module. You configure this port by configuring the IP address for the I/O module (see the User's Guide or Command-Line Interface Reference Guide for your management module type for instructions).

Note: Pass-thru modules have no internal Ethernet port.

To communicate with the blade servers for functions such as deploying an operating system or application program, you also will need to configure at least one external (in-band) port on an Ethernet switch module. See the BladeCenter Management

Module User’s Guide or the BladeCenter Management Module Command-Line Interface Reference Guide for information about configuring external ports on I/O

modules.

Note: If a pass-thru module is installed in I/O-module bay 1 or 2 (instead of an Ethernet switch module), you will need to configure a port on the network switch to which the pass-thru module is connected.

Management module and advanced management modules support different types of remote access. See the documentation for your management module type for information and instructions.

The Web-based user interface and command-line interface communicate with the management and configuration programs that are part of the firmware that comes with the management module. You can use these programs to perform tasks such as:

v Defining the login IDs and passwords v Selecting recipients for alert notification of specific events

v Monitoring the status of the BladeCenter unit and blade servers v Controlling the BladeCenter unit and blade servers v Accessing the I/O modules to configure them v Changing the drive startup sequence in a blade server v Setting the date and time v Using a remote console for the blade servers v Changing ownership of the keyboard, video, and mouse v Changing ownership of the optical drive, and USB port. (The optical drive in the

BladeCenter unit is viewed as a USB device by the blade server operating system.)

Note: The IBM Director program is a system-management tool that comes with the BladeCenter unit. To configure the remote alert recipients for IBM Director over LAN, the remote alert recipient must be an IBM Director-enabled server.

You also can use the management and configuration programs to view some of the blade server configuration settings. See the User's Guide or Command-Line Interface Reference Guide for your management module type for more information.

BladeCenter unit power requirement

The power supply modules in the BladeCenter unit must be connected to 220 V ac power only. The BladeCenter unit comes with two power cords to connect the BladeCenter unit to the power distribution unit (PDU).

BladeCenter power configuration

The power modules in power bays 1 and 2 provide power to blade bays 1 through 6 and to common components in the BladeCenter unit. The power modules in power bays 3 and 4 provide power to blade bays 7 through 14. Power modules must always be present in power bays 1 and 2.

Attention:

Non-redundant power is not supported by the BladeCenter E unit. Power modules must always be present in power bays 1 and 2. When any blade server or option is in blade bay 7 through 14, power modules must be present in power bays 1 and 2, and power modules must be present in power bays 3 and 4.

If a power module fails or an ac power failure occurs, a BladeCenter unit configured for redundant power operation will operate in a nonredundant mode, and the blower modules will run at full speed. You must replace the failing power module or restore ac power as soon as possible to regain redundant power operation and to reset the blower modules to their normal operating speed.

See the IBM BladeCenter Power Supply Modules option documentation and the BladeCenter Type 8677 Installation and User’s Guide for more information.

Firmware updates

The firmware for the management module and other BladeCenter components is periodically updated and is available for download on the Web. Go to http://www.ibm.com/support/ to get the latest level of firmware, such as BIOS code and device drivers.

22 BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide

Important: Some cluster solutions require specific code levels or coordinated code

updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code.

Note: When replacing BladeCenter components, you might have to update the management module or other components with the latest version of firmware.

Configuring the BladeCenter unit

General configuration of the BladeCenter unit and installed components is performed through the management module. See the BladeCenter Management

Module User’s Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for information and instructions. Some devices in the

BladeCenter unit, such as I/O modules and blade servers, might also require additional configuration. See the documentation that comes with each device for information and instructions.

Configuring the management module

All management modules are preconfigured with the same static IP address. You can use the management module to assign a new static IP address. To establish connectivity, the management module attempts to use Dynamic Host Control Protocol (DHCP) to acquire its initial IP address for the management-module Ethernet port. If DHCP is not installed or is enabled and fails, the management module uses the static IP address. Use the management module to configure other BladeCenter component settings such as user accounts, DHCP, or Wake on LAN. See the BladeCenter Management Module User’s Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for instructions.

Communicating with the IBM Director software

Notes:

1. See the illustration on page 27 for an example of a typical network configuration. See the IBM BladeCenter Planning and Installation Guide for more examples of network configurations. You can obtain the planning guide from http://www.ibm.com/systems/support/.

2. The IBM Director CD comes with the BladeCenter unit.

To communicate with the BladeCenter unit, the IBM Director software needs a managed object (in the Group Contents pane of the IBM Director Management Console main window) that represents the BladeCenter unit. If the BladeCenter management module IP address is known, the network administrator can create an IBM Director managed object for the unit. If the IP address is not known, the IBM Director software can automatically discover the BladeCenter unit (out-of-band, using the Ethernet port on the BladeCenter management module) and create a managed object for the unit.

For the IBM Director software to discover the BladeCenter unit, your network must initially provide connectivity from the IBM Director server to the BladeCenter management-module Ethernet port. To establish connectivity, the management module attempts to use DHCP to acquire its initial IP address for the Ethernet port. If the DHCP request fails, the management module uses a static IP address. Therefore, the DHCP server (if used) must be on the management LAN for your BladeCenter unit.

Chapter 2. Configuring your BladeCenter unit 23

Notes:

1. All management modules are preconfigured with the same static IP address. You can use the management-module Web interface or command-line interface to assign a new static IP address for each BladeCenter unit. If DHCP is not used and you do not assign a new static IP address for each BladeCenter unit before attempting to communicate with the IBM Director software, only one BladeCenter unit at a time can be added to the network for discovery. Adding multiple units to the network without a unique IP address assignment for each BladeCenter unit results in IP address conflicts.

2. For I/O-module communication with the IBM Director server through the management-module external Ethernet port, the I/O module internal network interface and the management-module internal and external interfaces must be on the same subnet.

Configuring I/O modules

You must install and configure at least one external (in-band) port on an Ethernet switch module in I/O-module bay 1 to communicate with the Ethernet controllers that are integrated in each blade server. See the BladeCenter Management Module

User’s Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for information about configuring external ports on I/O modules.

For I/O-device settings, see the documentation that comes with your I/O device. See “I/O (switch) modules” on page 34 for information about the location and purpose of each I/O module.

Notes:

1. If a pass-thru module is installed in I/O-module bay 1, you must configure the network switch that the pass-thru module is connected to; see the documentation that comes with the network switch.

2. You can set up Ethernet failover by installing an Ethernet switch module in I/O-module bay 2.

Configuring blade servers

To achieve communication redundancy on a blade server, you must configure the Ethernet controllers on the blade servers for failover. When failover occurs on a blade server, the secondary Ethernet controller takes over network communications, using the I/O module that is associated with that controller. Install a pair of Ethernet switches in I/O-module bays 1 and 2; then, configure them and your network infrastructure so that they can direct traffic to the same destinations. You can also install a pass-thru module that is connected to an external Ethernet switch in either or both of these I/O-module bays. See the documentation that comes with your blade server and operating system for instructions.

Using IBM Director

The IBM Director program is a system-management product that comes with the BladeCenter unit. Through the remote connection on the management module, you can use the IBM Director software at the IBM Director console to configure the BladeCenter unit, modify the configuration, and set up more advanced features.

Notes:

1. Some tasks, such as software distribution, require an in-band connection from the Director server through a campus (public) LAN to an I/O module port.

2. To manage BladeCenter redundant management modules with the IBM Director software, IBM Director version 4.1.01 or greater is required.

24 BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide

The IBM Director software includes the IBM BladeCenter Deployment Wizard.

About the wizard

The BladeCenter Deployment Wizard is integrated into the IBM Director management software. The wizard walks you through initial startup and configuration of one or more BladeCenter units.

In addition to performing initial configuration on BladeCenter units, you can use the built-in IBM Director tasks in the wizard to modify the configuration and to set up more advanced features.

You can also create a reusable profile in the wizard for configuring or reconfiguring BladeCenter units. The profile is a noninteractive script that can run as scheduled or as part of an Event Action Plan. With this feature you can define policies to reconfigure a BladeCenter unit on demand, responding to hardware failures or other IBM Director events.

Specifically, you can use the BladeCenter Deployment wizard to perform the following tasks:

v Perform all initial network configuration, including configuring IP addresses for the

v Set up the initial security profile for the BladeCenter unit, including user names,

v Optionally configure external switch module ports for multi-port link aggregation

(trunking).

Starting the wizard

Start the wizard from the IBM Director Management Console on the Director server.

1. Select one or more BladeCenter units from the middle (contents) pane of the console window.

Note: A lock icon beside a newly discovered BladeCenter unit indicates that the Director server cannot log into the management module for that BladeCenter unit, which can mean that the management module has not been configured yet. You might want to select that BladeCenter unit for initial configuration through the wizard.

2. Perform either of the following actions:

v Right-click the selected BladeCenter units (managed objects). v Drag the wizard task from the right-most pane (under BladeCenter in the task

BladeCenter networking guidelines

Your networking administrator should assist in the configuration of the network infrastructure prior to connecting the BladeCenter unit to the LAN switch or similar network device. This section provides additional guidelines that might be useful in setting up your system.

A BladeCenter chassis with two Ethernet switch modules and one management module has the following internal configuration:

100 Mbps links

Each blade server has two independent Ethernet controllers, each with its own MAC address and a dedicated 1000-Mbps link to one of the I/O modules (Controller 1 to Switch A and Controller 2 to Switch B in this diagram). In this configuration (the default), the blade servers share access to four external ports on each I/O module. There is no internal data path between the two switches within the BladeCenter chassis; an external network device is required for data packets to flow from one internal switch to the other.

The management module has a separate internal 100-Mbps link to each switch. These links are for internal management and control only. No data packets are allowed to flow from application programs on the blade servers to the management module over this path. A separate, nonswitched path (not shown) is used for communication between the management module and a service processor on each blade server.

A typical, preferred BladeCenter network topology is shown in the following illustration. See the IBM BladeCenter Planning and Installation Guide for more information and other topologies and guidelines.

In this configuration, each BladeCenter unit contains two Ethernet switch modules and one management module. The external ports on the switch modules are configured for multi-port link aggregation groups, or trunks, as are the corresponding ports on the attaching external LAN switches. Additionally, every port in the switch module in I/O-module bay 1 (switch A in this illustration) in the BladeCenter units is connected to the same external LAN switch and every port in the switch module in I/O-module bay 2 (switch B in this illustration) in the BladeCenter units is connected to the second external LAN switch.

Observe the following guidelines when creating this topology:

1. The external ports on the BladeCenter switch modules are designed for point-to-point, full-duplex operation to a compatible LAN switch or router. Configure a corresponding multi-port link aggregation group, or trunk, in both the switch module and the attaching LAN switch prior to installing the cables. The connection options are as follows, in order of preference:

v Multi-port Link Aggregation Group or Trunk, 1 Gbps (1000 Mbps) per port v Single-uplink port, 1 Gbps v Multi-port Link Aggregation Group or Trunk, 100 Mbps per port

2. Connect the management module 10/100 Mbps Ethernet port to a separate Layer 2 network if possible, for the best security. If a separate network is not available, you can attach the Ethernet ports of the management module and switch modules to the same Layer 2 network.

3. Avoid network configurations that could lead to data loops, if possible. Loops will be created if you connect multiple ports from the same switch module to the same Layer 2 network device without first enabling link aggregation. If you implement configurations that include data loops, it is essential that you enable Spanning Tree Protocol on the I/O module external ports.

Chapter 3. Diagnostics

This section provides basic troubleshooting information to help you resolve some common problems that might occur with your BladeCenter unit.

If you cannot locate and correct the problem using the information in this section, see Appendix A, “Getting help and technical assistance,” on page 85 for more information.

Diagnostic tools overview

The following tools are available to help you identify and solve hardware-related problems:

v Troubleshooting charts

These charts list problem symptoms and steps to correct the problems. See the Chapter 6, “Symptom-to-FRU index,” on page 59 for more information.

v Diagnostic programs and error messages

The built-in self-test (BIST) program checks the BladeCenter unit during startup and generates error messages if problems are found.

The system diagnostic program, Real Time Diagnostics Version 1.3, tests the major components of your BladeCenter unit. The Real Time Diagnostics software is available from the IBM Support Web site at http://www.ibm.com/systems/ support. It is run from the IBM Director Management Console window (under the BladeCenter task in the Task panel).

To obtain the Real Time Diagnostics program, go to the following Web site: http://www.ibm.com/systems/support.

1. Select Servers from the list at the left of the window.

2. Select Downloadable files from the list at the left of the window.

3. In the Downloadable files by category list, select Diagnostic.

4. Click the entry for Real Time Diagnostics and follow the instructions on that page.

v Light Path Diagnostics feature

Use the Light Path Diagnostics feature to identify system errors quickly. On the BladeCenter unit, the Light Path Diagnostics feature consists of the LEDs on the front and rear of the BladeCenter unit and on the front of the modules and blade servers.

Identifying problems using the Light Path Diagnostics feature

If the system-error LED on the system LED panel on the front or rear of the BladeCenter unit is lit, one or more error LEDs on the BladeCenter components also might be on. These LEDs help identify the cause of the problem.

This section provides the information to identify problems that might arise during installation using the Light Path Diagnostics feature.

To locate the actual component that caused the error, you must locate the lit error LED on that component.

For example:

A system error has occurred, and you have noted that the BladeCenter system-error LED is lit on the system LED panel. You then locate the module or blade server that also has an error LED lit (see “BladeCenter unit power, controls, and indicators” on page 11 for the location of error LEDs; see the documentation that comes with your blade server for the location of error LEDs on the blade). If the component is a module, replace the module. If the component is a blade server with its system-error LED lit, follow the instructions in the documentation that comes with the blade server to isolate and correct the problem.

Chapter 4. Installing options

This chapter provides instructions for adding options to your BladeCenter unit. Some option-removal instructions are provided in case you need to remove one option to install another.

Installing the BladeCenter unit in a rack

Statement 20:

CAUTION: To avoid personal injury, before lifting the unit, remove all the blades to reduce the weight.

Statement 4:

≥ 18 kg (39.7 lb) ≥ 32 kg (70.5 lb) ≥ 55 kg (121.2 lb)

CAUTION: Use safe practices when lifting.

Install the BladeCenter unit in a rack before installing any blade servers in the BladeCenter unit. If your BladeCenter unit has blade servers already installed, remove them first. Blade servers are installed from the front of the BladeCenter unit, without sliding the BladeCenter unit into or out of the rack. Detailed instructions for installing a BladeCenter unit in a rack are in the Rack Installation Instructions that come with your BladeCenter unit.

Installation guidelines

Before you begin to install options in your BladeCenter unit, read the following information:

v Read the “Important safety information” on page vii and the guidelines in

“Handling electrostatic discharge-sensitive devices” on page 90. This information will help you work safely with your BladeCenter unit and options.

v The orange color on components and labels in your BladeCenter unit identifies

hot-swap components. You can install or remove hot-swap modules and, with

some restrictions, hot-swap blade servers while the BladeCenter unit is running. For complete details about installing or removing a hot-swap component, see the detailed information in this chapter.

v The blue color on components and labels identifies touch points where you can

grip a component, move a latch, and so on.

v You do not need to disconnect the BladeCenter unit from power to install or

replace any of the hot-swap modules on the rear of the BladeCenter unit. You need to shut down the operating system and turn off a hot-swap blade server on the front of the BladeCenter unit before removing the blade server, but you do not need to shut down the BladeCenter unit itself.

v For a list of supported options for your BladeCenter unit, go to

http://www.ibm.com/pc/compat/ on the World Wide Web.

System reliability considerations

To help ensure proper cooling and system reliability, make sure that: v Each of the module bays on the rear of the BladeCenter unit has either a module

or filler module installed.

v Each of the blade bays on the front of the BladeCenter unit has either a blade

server or filler blade installed.

v Each of the drive bays in a blade server storage expansion option has either a

hot-swap drive or a filler panel installed.

v A removed hot-swap module, blade server, or drive is replaced within two

minutes of removal.

v Cables for the option modules are routed according to the illustrations and

instructions in this document.

v A failed blower is replaced as soon as possible, to restore cooling redundancy.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To

avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted

metal part of the BladeCenter unit or rack where the BladeCenter unit is installed for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package, and install it directly into the system unit

without setting the device down. If it is necessary to set down the device, place it back into its static-protective package. Do not place the device on your system unit or on a metal surface.

v Take additional care when handling devices during cold weather. Heating reduces

indoor humidity and increases static electricity.

Installing and removing modules

The procedures for installing or removing a module on the BladeCenter unit are nearly identical for all modules except the blower modules. To install or remove a blower module, see “Replacing a blower module” on page 47. To install or remove all other modules, follow the instructions in this section.

Every module is keyed so that it can be inserted only in an appropriate bay. You can insert an I/O module only in an I/O-module bay, for example. In addition, most modules must be installed in a specific sequence or under specific circumstances.

The BladeCenter modules

Your BladeCenter unit contains the following hot-swap modules: power modules, I/O modules, management module, and blower modules. See “Rear view” on page 10 for the location of each module. These modules supply common functions to the blade servers that are installed in the blade bays in the front of the BladeCenter unit.

The chassis and the management module supply I/O (optical drive, USB port, keyboard, video, and mouse) that is available to all the blade servers, selected by any one blade server at a time. The chassis can contain up to 14 blade servers.

Attention: To help ensure proper cooling, performance, and system reliability, make sure that each of the module bays on the rear of the BladeCenter unit has a module or filler module installed. When replacing a module, do not operate the BladeCenter unit for more than one minute without either a module or a filler module installed in each module bay.

Management module

Your BladeCenter unit comes with one hot-swap management module in the management bay. You can add a management module in management bay 2.

Note: Only one management module will be active; the second management module, if present, provides redundancy.

The management module functions as a service processor and a keyboard/video/mouse (KVM) multiplexor for the multiple blade servers. The management module also configures the BladeCenter unit and modules, configuring information such as the I/O module IP addresses. The management module provides the following external connections: keyboard, mouse, and video for use by a local console, and one RJ-45 connector for a 10/100 Mbps Ethernet remote management connection. Advanced management modules also provide an RJ-45 connector for serial management connection.

The service processor in the management module communicates with the service processor in each blade server for functions such as:

v Blade server power-on requests v Blade server error and event reporting v Blade server requests for keyboard, mouse, and video v Blade server requests for removable media drives

The management module also communicates with the I/O modules, power modules, blower modules, and blade servers to detect presence or absence and any error conditions, sending alerts when required.

Chapter 4. Installing options 33

I/O (switch) modules

For blade server communication with the network, your BladeCenter unit supports from one to four hot-swap I/O modules. Table 1 on page 35 identifies the type of I/O module you can install in each I/O-module bay. Go to the IBM Support Web site at http://www.ibm.com/systems/support to see the list of supported I/O modules. Your BladeCenter unit supports a minimum of one hot-swap Ethernet switch module or pass-thru module, in I/O-module bay 1. This I/O module provides an internal connection to Ethernet Link 1 in all the blade servers in the BladeCenter unit, up to 14 internal connections per I/O module. To provide an internal connection for Ethernet Link 2 in each blade server, install an Ethernet switch module or pass-thru module in I/O-module bay 2.

The BladeCenter unit also supports two additional I/O modules, for a total of four I/O modules. The two additional I/O modules support the network interface on the I/O expansion option installed on one or more blade servers in the BladeCenter unit.

Note: The BladeCenter unit supports either four Ethernet switch modules or two Ethernet switch modules and up to two fibre channel switch modules. No more than two fibre channel switch modules can be connected to the BladeCenter unit.

If you install an I/O expansion option on any blade server, you must install a hot-swap I/O module of the same network interface (or an optical pass-thru module) in I/O-module bay 3 to obtain network connection 3 for the option; to provide network connection 4 for the option, install the same type of I/O module in I/O-module bay 4 as you installed in I/O-module bay 3. For example, if you install a Fibre Channel I/O expansion option on a blade server, the I/O modules you install in I/O-module bays 3 and 4 must both be Fibre Channel or both be optical pass-thru, and all other I/O expansion options in the BladeCenter unit must also be Fibre Channel I/O expansion options.

Notes:

1. All blade server I/O expansion options in the BladeCenter unit must use the same type of network interface.

2. You can mix four-port 1-Gb Ethernet switch modules with other supported Ethernet switch modules to achieve the total number of Ethernet switch modules you need in the BladeCenter unit.

3. You can use a pass-thru module in any I/O-module bay, provided that the controller in the blade servers or I/O expansion options is compatible with the network switch to which the pass-thru module is connected.

34 BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide

The following table summarizes the types of modules that can be used in each I/O-module bay. See “Rear view” on page 10 for the location of the I/O-module bays on the BladeCenter unit.

Table 1. Hot-swap I/O module types by location

Bays I/O-module function Permissible I/O module

1 and 2 Network connections 1 and 2

(Ethernet) for all blade servers in the BladeCenter unit

3 and 4 Network connections 3 and 4 (from all

blade server I/O expansion options on blade servers in the BladeCenter unit)

One of the following combinations:

v Two Ethernet switch modules v Two pass-thru modules v One Ethernet module and one

pass-thru module

One of the following combinations:

v Two Ethernet switch modules v Two Fibre Channel switch modules v Two pass-thru modules v One pass-thru module and one

Ethernet switch module

v One pass-thru module and one Fibre

Channel switch module

Important:

v The modules used must support the

network interface used on the I/O expansion options.

v You cannot combine Ethernet and

Fibre Channel switch modules in bays 3 and 4.

Notes:

1. The enumeration of the Ethernet controllers in a blade server is operating-system dependent. You can verify the Ethernet controller designations a blade server uses through your operating system settings.

2. The routing of an Ethernet controller to a particular I/O-module bay depends on the type of blade server. You can verify which Ethernet controller is routed to which I/O-module bay by using the following test:

a. Install only one Ethernet switch module or pass-thru module, in I/O-module

bay 1.

b. Make sure the ports on the switch module or pass-thru module are enabled

(see the User's Guide or Command-Line Interface Reference Guide for your management module type for instructions).

c. Enable only one of the Ethernet controllers on the blade server. Note the

designation the blade server operating system has for the controller. d. Ping an external computer on the network connected to the switch module. If you can ping the external computer, the Ethernet controller you enabled is

associated with the switch module in I/O-module bay 1. The other Ethernet controller in the blade server is associated with the switch module in I/O-module bay 2.

3. If you have installed an I/O expansion option on a blade server, communications from the option are routed to I/O-module bays 3 and 4. You can verify which controller on the option is routed to which I/O-module bay by performing the test in note 2, using a controller on the I/O expansion option and a compatible switch module or pass-thru module in I/O-module bay 3 or 4.

Chapter 4. Installing options 35

Power modules

Note: The IBM BladeCenter E type 8677 and 1881 chassis must be configured to

support 2320-watt power modules. See the IBM BladeCenter E 2320 Watt Power Modules Installation Guide for specific information and instructions.

Your BladeCenter unit comes with one pair of 220-volt hot-swap power modules in power bays 1 and 2 that provides power to all the BladeCenter modules and to blade bays 1 through 6. The BladeCenter unit supports a second pair of power modules in power bays 3 and 4 that provides power to blade bays 7 through 14.

Each pair of power modules is redundant. If either power module fails, the remaining power module continues to supply power, but there is no redundancy; the failed power module must be replaced as soon as possible.

To provide true redundant power, BladeCenter power modules 1 and 3 must connect to a different ac power source than power modules 2 and 4. Connect BladeCenter power modules 1 and 3 to a different PDU than power modules 2 and 4; then, connect each PDU to an ac power source (building power source or service entrance) that is controlled by a separate circuit breaker.

The following table summarizes the application for each power module

Bays Power module function

1 and 2 Provides power to all the BladeCenter modules and to blade bays 1 through 6 3 and 4 Provides power to blade bays 7 through 14

Power modules are not needed in bays 3 and 4 until you begin installing blade servers and options in blade bays 7 through 14.

Note: If you install a blade server that has a storage expansion unit option attached in blade bay 6, the option will use blade bay 7; power modules will be required in power bays 1, 2, 3 and 4.

Each active power module supplies 12 volts of power to the blade bays it services.

Important: Plug one end of each power-module power cord into the power module; plug the other end of the power cord into a 220-volt power distribution unit (PDU).

Blower modules

Your BladeCenter unit comes with two hot-swap blowers for cooling redundancy. The blower speeds vary depending on the ambient air temperature at the front of the BladeCenter. If the ambient temperature is 72°F or below, the BladeCenter blowers will run at 30% of their maximum rotational speed, increasing their speed as required to control internal BladeCenter temperature. If the ambient temperature is above 72°F, the blowers will run at 80% of their maximum rotational speed, increasing their speed as required to control internal BladeCenter temperature. If a blower fails, the remaining blower continues to cool the BladeCenter unit and blade servers.

Important: Replace a failed blower as soon as possible, to restore cooling redundancy.

Chapter 4. Installing options 39

Installing and removing the acoustic module option

For server environments where noise reduction is essential, you might choose to install the BladeCenter acoustic attenuation module option (acoustic module) on the BladeCenter unit. The acoustic module reduces the sound level of the BladeCenter unit to below 7.2 Bel using a T-shaped baffle. The acoustic module is installed on the back of the BladeCenter unit, directly covering the blower modules and partially covering the other modules. The system LED panel is replicated on the acoustic module for visibility. Installing an acoustic module increases the length of a BladeCenter unit and requires use of an enterprise rack.

Installing the acoustic module option

Complete the following steps to install an acoustic module option on the BladeCenter unit:

1. Place the acoustic module over the blower modules, aligning the corners of the acoustic module back with the guides on the chassis, and pushing the shaft into the hole between the blower modules.

2. Rotate the acoustic module handle approximately 2 turns clockwise until it tightens the acoustic module firmly into place.

Installing and removing blade servers

Your BladeCenter unit supports up to 14 high-performance blade servers. Each blade server is an enclosure that contains microprocessors, memory, a control chip set, an I/O bus, Ethernet controllers, hard disk drives, customer interface controls, and connectors for expansion options. The blade server receives its power, network connection, and I/O devices (removable media drives, keyboard, mouse, and video ports, USB port, remote monitoring port) from the BladeCenter unit, reducing the server physical size and reducing the number of cables needed.

Blade server expansion options

Some blade servers contain connectors for options that add capabilities to the blade server. You can add these options before installing the blade server in the BladeCenter unit.

Go to http://www.ibm.com/pc/compat/ on the World Wide Web for a list of available options for your IBM blade server.

I/O expansion option

Some blade servers have connectors for adding an I/O expansion option, such as the IBM HS20 Fibre Channel Expansion Card. The BladeCenter unit routes network communication signals from the I/O expansion option to I/O modules 3 and 4 on the BladeCenter unit. The I/O expansion option is attached directly to the blade server but does not occupy an additional blade bay.

Chapter 4. Installing options 41

Note: If an I/O expansion option is installed on any blade server, I/O modules for that network interface must be installed in I/O-module bays 3 and 4 on the BladeCenter unit. See “I/O (switch) modules” on page 34 for more information.

Storage-expansion option

Some blade servers have a connector for adding a SCSI expansion unit, such as the IBM HS20 SCSI Storage Expansion Unit. The storage expansion unit supports up to two hot-swap SCSI hard disk drives. The expansion option is attached directly to the blade server.

Note: The SCSI controller in the SCSI storage expansion unit supports RAID level-1 (embedded mirroring).

Important:

1. To ensure proper cooling and system reliability, make sure that each of the SCSI hard disk drive bays on the SCSI storage expansion unit contains either a hot-swap SCSI hard disk drive or a filler panel.

2. Do not install a drive into IDE connector 2 on the blade server if you intend to also install an I/O expansion option. The I/O expansion option occupies the same area as the second IDE drive.

3. Two IDE drives can be used to implement and manage RAID level-1 under both the Linux and Microsoft Windows 2000 operating systems. Details of the implementation for Microsoft Windows 2000 can be found at http://support.microsoft.com/default.aspx?scid=kb;EN-US;q302969 on the World Wide Web.

Completing the installation

After you connect the cables to the modules and route the cables (if necessary, see the Rack Installation Instructions for information about routing the cables), start the BladeCenter unit (if it is not already started), and verify that it is working properly, as follows:

1. Start the BladeCenter unit by connecting the power-module power cords to a 220-volt power source (a 220-volt power distribution unit (PDU) that is connected to a 220-volt ac power outlet or directly to a 220-volt ac power outlet).

2. Make sure the LEDs on the modules indicate that they are operating properly. Verify that:

v The dc power LED and the ac power LED on each power module are lit and

that the power module error LED (2320-watt power modules only) on each power module is not lit.

v The OK LED on each management module is lit. v The OK LED on each I/O module is lit.

3. Make sure the Power-on LED on each blade server is lit, either steady or blinking.

See “BladeCenter unit power, controls, and indicators” on page 11 for information about starting the BladeCenter unit and the location of the LEDs on the modules. See the Installation and User’s Guide for your blade server for the location of the LEDs on the blade servers.

Input/output connectors

Your BladeCenter has one Universal Serial Bus (USB) version 1.1 or 2.0 connector, depending on BladeCenter unit type, on the front of the BladeCenter unit. All other input/output connectors are provided by devices installed in the BladeCenter unit, such as management modules or I/O modules. See the documentation for these devices for information about the input/output connectors and their function.

Use the USB connector to connect a USB device other than a mouse or keyboard to the BladeCenter unit. Using Plug and Play technology, USB devices are configured automatically.

Device Suggested action Blade server problem

Blade servers turn off for no apparent reason.

Blade server does not turn off during Red Hat Linux 7.3 shutdown.

Blade server does not turn off during SuSE Linux 8.0 shutdown.

All blade bays must have a blade server, expansion unit, or filler blade in them. Blade bays that do not have these items installed or have them installed improperly disturb airflow in the BladeCenter unit with an adverse effect on BladeCenter unit cooling. If the BladeCenter unit begins to overheat, blade server processors will begin to slow down and will eventually turn off the system.

Issuing any of the Linux shutdown commands shuts down the operating system, but does not turn off the blade server. The blade server shuts down to the point where a message is displayed on the management module saying that the blade server is off, but the blade server power-on LED remains lit.

Complete the instructions provided for Red Hat Linux in the User's Guide or the Command-Line Interface Reference Guide for your management module type to enable Wake On LAN for both onboard Broadcom integrated Ethernet controllers. This will allow the blade server to restart using Wake on LAN even if the Linux shutdown is incomplete and the blade server does not turn off.

Forcing a blade server to turn off

Complete the following steps to turn off a blade server after an incomplete Linux shutdown:

1. Manually press the power-control button on the front of the blade server (behind

the control panel door) to turn off the blade server. Turning off the blade server in this way is considered an improper shutdown by the Wake on LAN feature, and the Wake on LAN feature will not restart the blade server.

2. Unlatch and slide the blade server partially out of the BladeCenter; then, reinstall

it to reset the blade server power state and re-enable its previously programmed Wake on LAN capability.

Issuing any of the Linux shutdown commands shuts down the operating system but does not turn off the blade server. The blade server shuts down to the point where a message is displayed on the management module saying that the blade server is off, but the blade server power-on LED remains lit.

A blade server running SuSE Linux 8.0 will not turn off during shutdown if ACPI is not enabled. Complete the following steps to enable ACPI:

1. Type the following command: modprobe ospm_system

2. Type the following command to save this setting upon subsequent reboots: echo

"/sbin/modprobe ospm_system" >> /etc/init.d/boot.local

Blade server does not turn on, the amber system-error LED on the BladeCenter system-LED panel is lit, the amber blade error LED on the blade server LED panel is lit, and the system-error log contains the following message: "CRUs MisMatched".

The problem occurs after installing the second microprocessor option or after replacing a failed microprocessor in a two-way Blade server.

The processor with the lowest feature set and stepping level must be used as the Bootstrap Processor (BSP). This is Microprocessor 1 in location U66. Move the microprocessor in location U66 to location U70, and move the microprocessor in location U70 to location U66.

CD-ROM cannot be configured with a JS20 blade server but works with a HSxx blade server.

The customer interface card (FRU number 59P6629) is not compatible with the JS20 blade server and must be replaced with the latest level FRU. Note: The customer interface card installed in the BladeCenter is listed as the "media tray" instead of the "customer interface card" on the Hardware VPD view of the management-module web interface. The FRU number is also printed on the customer interface card. Replace the customer interface card with the latest level, see Chapter 7, “Parts listing, BladeCenter Type 8677 and 1881,” on page 79for the correct FRU number.

Some components do not report environmental status (temperature, voltage).

The green status dot for a component is not automatically a link to environmental information (temperature and voltage) for the component. Only the management module and blade servers have environmental information, and only the green dot for those components contains a link to environmental information.

Switching KVM control between blade servers gives USB device error.

If a blade server is under heavy load, it can take several minutes before it enumerates the USB devices connected to it. If control of the KVM and media tray is switched away from the blade server before this enumeration is complete, a USB device installation error might be displayed. Do not switch KVM control between blade servers until the mouse and keyboard are both working on the blade server that has control of the KVM and media tray.

“Unsafe Removal of Device” error message appears on blade server running Microsoft Windows 2000.

Before switching ownership of the media tray to another blade server, safely stop the media tray devices on the blade server that currently owns the media tray, similar to the following:

1. Double-click the Unplug or Eject Hardware icon in the Windows taskbar at the

bottom right of the screen.

2. Select USB Floppy, and click Stop.

3. Select USB Mass Storage Device, and click Stop.

4. Click Close.

You can now safely switch ownership of the media tray to another blade server.

“Media not found” error message and other file system error occur on a blade server running Linux or DOS.

Attempting to access the mounted optical drive or diskette drive (media tray) after it has been switched to another blade server results in I/O errors, even if the media tray has been switched back. Note: Because the BladeCenter unit uses a USB bus to communicate with the media tray devices, switching ownership of the media tray to another blade server is the same as unplugging a USB device.

v If a blade server tries to access the optical drive after it has been switched to

another blade server, a “Media not found” error occurs.

v If a blade server is running a DOS environment, such as when updating firmware

on the blade server, the firmware can be interrupted or corrupted when the media tray is switched away; you might need to call for service on the blade server.

v If a file handle was left open by switching the media tray away, the system

administrator will not be able to do a clean unmount (umount command) unless the unmount is forced by umount command parameters (“lazy umount”).

v If the system administrator is sharing out the optical drive for multiple users, that

network share is broken.

Before switching ownership of the media tray to another blade server, ensure that the optical drive and diskette drive are not mounted for the current blade server owner (check for open file handles and sharing out). If a firmware update is taking place on the blade server, do not switch the media tray to another blade server.

Remote control does not work with default SuSE Linux, version 8.0, display settings.

The remote console requires a display setting of 1024x768@60Hz in the blade server operating system. The default resolution in SuSE is 1024x768, but the default refresh rate falls somewhere between 50Hz and 60Hz. The remote console does not work for a blade server running SuSE with a display refresh rate other than exactly 60Hz. The message “eServer/No video available” displays.

Other operating systems do not exhibit the problem.

Set the refresh rate in the XF86Config file to exactly 60Hz.

There are two methods. v Method 1 (unattended network install, prevent the problem): Modify the

AutoYaST control file to specify 1024x768@60Hz.

1. Run the graphical interface to the AutoYaST control file to set the VESA video mode to 1040x768@60Hz. The graphical interface creates the AutoYaST control file.

2. Edit the resulting AutoYaST control file to set the value for min_vsync to 60.

During an unattended network install, the YaST program uses the AutoYaST control file to modify the XF86Config file (/etc/X11/XF86Config); these changes will cause XF86Config to set the display resolution to 1040x768 with a refresh rate of 60Hz.

This happens when you have not safely stopped the drives before switching ownership of the optical drive, diskette drive, and USB port (media tray). Note: Because the BladeCenter unit uses a USB bus to communicate with the media tray devices, switching ownership of the media tray to another blade server is the same as unplugging a USB device.

Ethernet controller problems

Operating systems number Ethernet controllers differently.

Enumeration of the Ethernet controllers in a blade server is operating-system dependent. In the blade server Configuration/Setup Utility program, the Ethernet port designated as Planar Ethernet 1 is routed to Ethernet switch module 2 and the Ethernet port designated as Planar Ethernet 2 is routed to Ethernet switch module 1.

Verify the designations through your operating system settings or by testing:

1. Install only one switch module, in I/O-module bay 1.

2. Enable only one of the Ethernet controllers on the blade server. Make note of the

3. Ping an external computer on the network connected to the switch module.

If you can ping the external computer, the Ethernet controller you enabled is the upper controller in the blade server and is associated with Ethernet switch 1.

Ethernet switch module problems

First ping from Ethernet switch module through Telnet reports failure.

When you use the Ethernet switch module Telnet interface to request the switch module to ping something, the first ping response reports a failure, although the other repetitions might report success. This occurs regardless of whether the switch module port the pinged object is connected to is internal or external, and applies to pinging blade servers but not to pinging the management module or objects connected to its external Ethernet port, such as the network management station. To get accurate results, always specify multiple repetitions (>1) in the ping request, and ignore the first ping response from that request. See the IBM 4-Port Gb Ethernet Switch Module for BladeCenter Installation Guide for instructions on how to ping through the Telnet interface.

The default IP address set by the Ethernet switch module does not match the one assigned by the management module.

Updating the Ethernet switch module configuration through the management module does not save the switch NVRAM.

If the Wake-on-LAN (WOL) feature is disabled on a blade server, and the blade server is turned off, the switch module internal port link to that blade is down. This is not an error, but the graphic of the BladeCenter unit might show a blank panel instead of a blade server in that bay. Note: You can enable or disable the WOL feature on a blade server through the management-module Web interface or through the IBM Director console. Do not rely on the BladeCenter graphic in the Ethernet switch-module firmware Web interface to determine the presence or absence of blade servers in the BladeCenter unit.

The timestamp on entries in the Ethernet switch module log uses elapsed time (since last switch restart). The timestamp on entries restarts from 0 each time the switch is restarted, although the entries do remain in order of occurrence.

If an Ethernet cable is accidentally removed from the back of the BladeCenter unit, the small red X (disconnect notice) that normally would appear to indicate that the cable was disconnected will not appear in the bottom right of the screen. The disconnect notice does not appear because the blade server Ethernet controller connects to the Ethernet switch module through integrated circuitry inside the BladeCenter unit.

When troubleshooting Ethernet-related problems, ensure that the Ethernet cables on the back of the BladeCenter unit are connected properly.

When you use the management-module Web interface to update the Ethernet switch module configuration, the management module firmware writes its settings for the switch module only to the management module NVRAM; it does not write its settings for the switch module to the switch-module NVRAM.

If the switch module restarts when the management module is not able to apply the IP address it has in NVRAM for the switch module, the switch module will use whatever IP address it has in its own NVRAM. If the two IP addresses are not the same, you might not be able to manage the Ethernet switch module any more.

When you are redirecting the server console (remote console function) of a blade server that is running Microsoft Windows 2000 or Windows XP and using the Sun Java plug-in (Java Virtual Machine), the remote console can have keyboard entry problems.

Management-module problems

The management module password cannot be reset.

Management module does not complete changeover to redundant module on hardware failure.

Media tray problems

Media tray access is lost temporarily during management module restart.

Use the Microsoft Java Virtual Machine (JVM) or Java Runtime Environment (JRE) on the blade server instead of using the Sun Java Virtual Machine. The Microsoft JVM comes with the Windows XP Service Pack 1. You can obtain the Microsoft JVM for Windows 2000 from the Microsoft corporation. If you are using the Internet Explorer browser, version 6.0 or later, to log into the management module and use the remote control function, you must also adjust the browser settings:

1. Click Tools → Internet Options → Advanced tab.

2. Under the Java (Sun) section, uncheck the checkbox next to ’Use Java 2 v1.4. for <applet> (requires restart)’

If you forget the management-module password, you will not be able to access the BladeCenter management module. The management-module password cannot be overridden, and the management module will need to be replaced.

Replace the management module.

When the BladeCenter management module is restarted, use of the media tray (removable media drives) is lost temporarily. If you or a failure condition initiates a management module restart while I/O activity is taking place on the media tray, the disruption can interrupt reads to the optical drive or lose data being written to a diskette or USB device. Note: You can restart the management module through the Web interface to the management module or from a network management station such as the IBM Director console. Some failures on the BladeCenter unit can result in the management module restarting automatically.

Make sure there is no I/O activity on the media tray before you restart the management module.

The monitor attached to the BladeCenter management module normally shows the video output from the blade server that is the current owner of the keyboard, video, and mouse (KVM). When there is no actively selected video from any blade server, the video from blade server 14 is routed to the management module. While the management module is restarting, there is temporarily no current KVM owner. The video from blade server 14 displays on the monitor briefly until the management module uses its NVRAM values to reestablish ownership of the KVM and media tray (optical drive, diskette drive, and USB port). After that, the video from the blade server that is the current KVM owner displays on the monitor.

1. The system power cord is plugged into the BladeCenter power module and a working 220-volt PDU or electrical outlet.

If the monitor self-tests show the monitor is working properly, consider the location of the monitor. Magnetic fields around other devices (such as transformers, appliances, fluorescent lights, and other monitors) can cause screen jitter or wavy, unreadable, rolling, or distorted screen images. If this happens, turn off the monitor. (Moving a color monitor while it is turned on might cause screen discoloration.) Then move the device and the monitor at least 305 mm (12 in.) apart. Turn on the monitor.

1. To prevent diskette drive read/write errors, be sure the distance between monitors and diskette drives is at least 76 mm (3 in.).

2. Non-IBM monitor cables might cause unpredictable problems.

3. An enhanced monitor cable with additional shielding is available for the 9521 and 9527 monitors. For information about the enhanced monitor cable, contact your IBM reseller or IBM marketing representative.

If the problem remains, replace the monitor. If the wrong language is displayed, update the firmware in the management module

with the correct language. If the problem remains, replace the management module.

If, while installing Red Hat Linux 7.3 to a blade server, you or someone else selects a different blade server as owner of the keyboard, video, and monitor (KVM), you might lose mouse function for the installation process.

Do not switch KVM owners until the installation process begins to install the packages (after the ’About to Install’ window).

Device Suggested action

Mouse is not detected during SuSE installation.

The installation of the SuSE Linux version 8.0 operating system does not detect the mouse.

You will need to select the mouse manually. Download the latest operating system installation instructions for your operating system from the IBM Support Web page at http://www.ibm.com/systems/support/. The steps for selecting the mouse are described in the instructions for your operating system.

Mouse offset problems occur when using remote console and running X.

When you are using the remote console on a blade server that is running X Windows in Red Hat Linux 7.3 or SuSE Linux version 8.0, you see two cursor arrows on the screen, widely spaced, one white and one black.

Configure Linux and X Windows for accurate mouse tracking. See the online help information in the management module configuration and management software for instructions (Blade Tasks → Remote Control, click the circled question mark next to

Redirect Server Console, read the section titled Notes on mouse support under Linux).

Power problems

The system does not power on.

Verify that:

1. The power cables are properly connected to the power modules in the BladeCenter unit.

2. The 220-volt PDU functions properly.

3. The ac and dc power LEDs on the power module are on and the power module error LED (2320-watt power modules only) on the power module is off.

4. If you just installed an option, remove it, and restart the BladeCenter unit. If the BladeCenter unit now turns on, you might have installed more options than the power module supports. You might need to install a power module in power bay 3 or 4.

If the problem remains, go to “Undetermined problems” on page 77.

Option problems

An IBM option that was just installed does not work.

Verify that: v The option is designed for the BladeCenter unit. See the “Server Support”

flowchart for information about obtaining ServerProven from the World Wide Web.

v You followed the installation instructions that came with the option. v The option is installed correctly. v You have not loosened any other installed options or cables.

If the problem remains, replace the option.

An IBM option that used to work does not work now.

Verify that all of the option hardware and cable connections are secure. If the option comes with its own test instructions, use those instructions to test the option. If the problem remains, replace the option.

Service processor problems

Service processor in the management module reports a general monitor failure.

Disconnect the BladeCenter unit from all electrical sources, wait for 30 seconds, reconnect the BladeCenter unit to the electrical sources, and restart the server. If a problem remains, replace the management module.

Device Suggested action

Updating the I/O-module configuration through the I/O-module does not save the management-module NVRAM.

If you log in to the Ethernet switch module directly (through the Ethernet switch-module Web interface or Telnet interface instead of through the management module Web interface) and update the I/O module configuration, saving the new configuration saves only to the I/O-module NVRAM, not to the management-module NVRAM. The management module will not be able to communicate with the I/O module.

See the User's Guide or Command-Line Interface Reference Guide for your management module type for information about how to change the New Static IP Configuration values to match the ones in Current IP Configuration, and apply the configuration.

Undetermined problems

Use the information in this section if the diagnostic tests did not identify the failure, the devices list is incorrect, or the system is inoperative.

Notes:

1. When troubleshooting a BladeCenter problem, you must determine if the problem is actually a blade server problem.

v If the BladeCenter unit contains more then one blade server installed and

only one of the blade servers exhibits the symptom, most likely it is a blade server problem.

v If all blade servers exhibit the same symptom, most likely it is a BladeCenter

unit problem.

2. Damaged data in CMOS can cause undetermined problems.

3. Damaged data in BIOS code can cause undetermined problems.

Check the LEDs on all the power supplies. If the LEDs indicate the power modules are working correctly and reseating the BladeCenter components does not correct the problem, remove or disconnect the BladeCenter components one at a time to a minimal configuration or until you locate the problem. You do not need to remove power from the system. Complete the following steps to remove the components.

1. Remove the acoustic attenuation models, if attached.

2. Shut down the operating system on all blade servers.

3. Turn off the blade servers; then, open the release lever on each blade server and slide it out of the bay approximately 1 inch.

4. Disconnect power modules 2, 3, and 4 one at a time. To do this, first remove the power cord; then, pull the release lever all the way down. Slide the power module out of its bay approximately 1 inch.

5. Disconnect the I/O modules one at a time. To do this, remove all cables connected to the I/O module; then, pull the release lever all the way down. Slide the I/O module out of the bay approximately 1 inch.

Note: The minimum configuration is:

v 8677 or 1881 unit (media tray may be connected). v power module in bay 1. v management module.

The BladeCenter unit can be checked with the management module Web interface at each stage as components are removed, and will work in the minimal configuration. If the minimal configuration does not work, do the following.

1. Recheck the management-module network settings.

2. Disconnect the media tray, and slide it out of the bay approximately 1 inch.

Chapter 6. Symptom-to-FRU index 77

Note: The front and rear panel LEDs will not function with the media tray removed.

3. Move the power module to bay 2.

4. Remove and reconnect the power cord to the power module.

5. Replace the management module.

6. Replace the power module.

7. Replace the midplane.

Problem determination tips

Due to the variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. If possible, have this information available when requesting assistance from Service Support and Engineering functions.

v Machine type and model v Microprocessor or hard disk upgrades v Failure symptom

– Do diagnostics fail? – What, when, where, single, or multiple systems? – Is the failure repeatable? – Has this configuration ever worked? – If it has been working, what changes were made prior to it failing? – Is this the original reported failure?

v Diagnostics version — type and version level v Hardware configuration

– Print (print screen) configuration currently in use – BIOS level

v Operating system software — type and version level

Note: To eliminate confusion, identical systems are considered identical only if they:

1. Are the exact machine type and models

2. Have the same BIOS level

3. Have the same adapters/attachments in the same locations

4. Have the same address jumpers/terminators/cabling

5. Have the same software versions and levels

6. Have the same diagnostics code (version)

7. Have the same configuration options set in the system

8. Have the same setup for the operation system control files

Comparing the configuration and software set-up between “working” and “non-working” systems will often lead to problem resolution.

Appendix B. Related service information

Note: The service procedures are designed to help you isolate problems. They are

written with the assumption that you have model-specific training on all computers, or that you are familiar with the computers, functions, terminology, and service information provided in this manual.

Safety information

The following section contains the safety information that you need to be familiar with before servicing an IBM computer.

General safety

Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after

maintenance.

v When lifting any heavy object:

1. Ensure you can stand safely without slipping.

2. Distribute the weight of the object equally between your feet.

3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any objects

that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

v Do not perform any action that causes hazards to the customer, or that makes

the equipment unsafe.

v Before you start the machine, ensure that other service representatives and the

customer's personnel are not in a hazardous position.

v Place removed covers and other parts in a safe place, away from all personnel,

while you are servicing the machine.

v Keep your tool case away from walk areas so that other people will not trip over

it.

v Do not wear loose clothing that can be trapped in the moving parts of a machine.

Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

v Insert the ends of your necktie or scarf inside clothing or fasten it with a

nonconductive clip, approximately 8 centimeters (3 inches) from the end.

v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your

clothing. Remember: Metal objects are good electrical conductors.

v Wear safety glasses when you are: hammering, drilling soldering, cutting wire,

attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

v After service, reinstall all safety shields, guards, labels, and ground wires.

Replace any safety device that is worn or defective.

v Reinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION: Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the server covers, unless instructed otherwise in the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that do not insulate you when working with live electrical currents.

Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

v Find the room emergency power-off (EPO) switch, disconnecting switch, or

electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Disconnect all power before:

– Performing a mechanical inspection – Working near power supplies – Removing or installing main units

v Before you start to work on the machine, unplug the power cord. If you cannot

unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

v If you need to work on a machine that has exposed electrical circuits, observe

the following precautions: – Ensure that another person, familiar with the power-off controls, is near you.

Remember: Another person must be there to switch off the power, if necessary.

– Use only one hand when working with powered-on electrical equipment; keep

the other hand in your pocket or behind your back. Remember: There must be a complete circuit to cause electrical shock. By

observing the above rule, you may prevent a current from passing through your body.

– When using testers, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you

from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

v Regularly inspect and maintain your electrical hand tools for safe operational

condition.

88 BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide

v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit. First, check that

it has been powered-off.

v Always look carefully for possible hazards in your work area. Examples of these

hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.

v Do not touch live electrical circuits with the reflective surface of a plastic dental

mirror. The surface is conductive; such touching can cause personal injury and machine damage.

v Do not service the following parts with the power on when they are removed from

their normal operating places in a machine: – Power supply units – Pumps – Blowers and fans – Motor generators and similar units. (This practice ensures correct grounding of

the units.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present: v Electrical hazards, especially primary power (primary voltage on the frame can

cause serious or fatal electrical shock).

v Explosive hazards, such as a damaged CRT face or bulging capacitor v Mechanical hazards, such as loose or missing hardware

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1. Check exterior covers for damage (loose, broken, or sharp edges).

2. Turn off the computer. Disconnect the power cord.

Appendix B. Related service information 89

3. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure

third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.

b. The power cord should be the appropriate type as specified in the parts

listings.

c. Insulation must not be frayed or worn.

4. Remove the cover.

5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

7. Check for worn, frayed, or pinched cables.

8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits (Is) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the server, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

1. Use product-specific ESD procedures when they exceed the requirements noted here.

2. Make sure that the ESD-protective devices you use have been certified (ISO

9000) as fully effective.

When handling ESD-sensitive parts:

v Keep the parts in protective packages until they are inserted into the product. v Avoid contact with other people. v Wear a grounded wrist strap against your skin to eliminate static on your body. v Prevent the part from touching your clothing. Most clothing is insulative and

retains a charge even when you are wearing a wrist strap.

v Use the black side of a grounded work mat to provide a static-free work surface.

The mat is especially useful when handling ESD-sensitive devices.

v Select a grounding system, such as those in the following list, to provide

protection that meets the specific service requirement.

Note: The use of a grounding system is desirable but not required to protect against ESD damage.

– Attach the ESD ground clip to any frame ground, ground braid, or green-wire

ground.

– Use an ESD common ground or reference point when working on a

double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.

– Use the round ground-prong of the ac plug on ac-operated computers.
