KVM select button: Press this button to associate the shared BladeCenter unit keyboard, video, and mouse port (KVM) with the blade server. The LED on this button flashes while the request is being processed and then is lit when the ownership of the keyboard, video, and mouse has been transferred to the blade server. It can take approximately 20 seconds to switch the keyboard, video, and mouse control to the blade server.

Using a keyboard that is directly attached to the management-module, you can press keyboard keys in the following sequence to switch KVM control between blade servers:

NumLock NumLock bay_number Enter

Where bay_number is the two-digit number of the blade bay in which the blade server is installed. A blade server that occupies more than one blade bay is identified by the lowest bay number that it occupies.

If there is no response when you press the KVM select button, you can use the management-module Web interface to determine whether local control has been disabled on the blade server.

Notes:

1. The operating system in the blade server must provide USB support for the

blade server to recognize and use the keyboard and mouse, even if the keyboard and mouse have PS/2-style connectors.

2. If you install a supported Microsoft Windows operating system on the blade

server while it is not the current owner of the KVM, a delay of up to 1 minute occurs the first time that you switch the KVM to the blade server. During this one-time-only delay, the blade server device manager enumerates the keyboard, video, and mouse and loads the device drivers. All subsequent switching happens in the normal KVM switching time frame (up to 20 seconds).

Media-tray select button: Press this button to associate the shared BladeCenter unit media tray (removable-media drives and front-panel USB ports) with the blade server. The LED on the button flashes while the request is being processed,

Firmware updates

IBM periodically makes BIOS, service processor (BMC), diagnostic firmware, and other firmware updates available for the blade server. Go to http:// www.ibm.com/bladecenter/ to download the latest firmware for the blade server; then, install any updates using the instructions that are included with the downloaded file.

Important: To avoid problems and to maintain system performance, always make sure that the BIOS, service processor (BMC), and diagnostic firmware levels are consistent for the blade servers within the BladeCenter unit.

Configuring the Gigabit Ethernet controller

One Ethernet controller is integrated on the blade server system board. A controller provides a 1000 Mbps full-duplex interface for connecting to one of the Ethernet-compatible I/O modules in I/O-module bays 1 and 2, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). The Ethernet controller on the system board is routed to a different I/O module in I/O-module bay 1 or bay 2. The routing from an Ethernet controller to an I/O-module bay varies according to the blade server type and the operating system that is installed.

You do not have to set any jumpers or configure the controller for the blade server operating system. However, you must install a device driver to enable the blade server operating system to address the Ethernet controller. For device drivers and information about configuring the Ethernet controller, see the Broadcom NetXtreme Gigabit Ethernet Software CD that comes with the blade server. To find updated information about configuring the controller, complete the following steps.

Note: Changes are made periodically to the IBM Web site. The actual procedure might vary slightly from what is described in this document.

1. Go to http://www.ibm.com/systems/support/.

2. Click Support.

3. Under Support information, click Product support and information.

4. Under Popular links, click Publications lookup.

5. From the Product family menu, select BladeCenter LS22 or BladeCenter LS42

and click Go.

Note: If an 1801 error code is displayed during startup and the startup process

stops, the BIOS is trying to copy too much data from the device boot ROM into write-protected RAM. To correct an 1801 error that halts the boot process, restart the blade server, start the Setup Utility program (see “Using the Setup Utility program” on page 11), and disable unnecessary ROM shadowing. Only the device boot ROMs that enable the following components must be shadowed during startup:

v Video

v Hard disk drive (if you are using this as a primary or secondary boot device)

v PXE (if you are using PXE as a primary or secondary boot device)

v One Ethernet controller (if you are using PXE as a primary or secondary boot

device)

Chapter 2. Configuring the blade server 17

The remaining options and components will be enabled by device drivers in the operating system.

Configuring a SAS RAID array

Two SAS drives can be used to implement and manage RAID level-0 (striping) or RAID level-1 (mirror) arrays in operating systems that are listed at http://www.ibm.com/servers/eserver/serverproven/compat/us/. For more information, see the Installation and User’s Guide.

Important: You must create the RAID array before you install the operating system on the blade server.

Use the LSI Configuration Utility program to configure the SAS RAID (see “Using the LSI Logic Configuration Utility program”).

Using the LSI Logic Configuration Utility program

You can use the LSI Logic Configuration Utility program to perform the following tasks:

v Set the SAS device scan order

v Set the SAS ID for the controller

v Manage the SAS RAID configuration

To start the LSI Logic Configuration Utility program, complete the following steps:

1. Turn on the blade server, and make sure that the blade server is the owner of

the keyboard, video, and mouse (see “Turning on the blade server” on page 5).

2. When the <<<Press Ctrl-C to start LSI Logic Configuration Utility>>>

prompt is displayed, press Ctrl+C.

3. Use the arrow keys to select the controller from the list of adapters; then, press

Enter.

4. Follow the instructions on the screen to change the settings of the selected

items; then, press Enter. If you select SAS Topology or Advanced Adapter

Properties, additional screens are displayed.

For information about the terms of the warranty and getting service and assistance, see the Warranty and Support Information document.

Installation guidelines

Before you remove or replace a component, read the following information:

v Read the safety information that begins on page “Safety statements” on page viii

and the guidelines in “Handling static-sensitive devices” on page 26. This information will help you work safely.

v When you install your new blade server, take the opportunity to download and

apply the most recent firmware updates. This step will help to make sure that any known issues are addressed and that your blade server is ready to function at maximum levels of performance. To download firmware updates for your blade server:

Note: Changes are made periodically to the IBM Web site. The actual procedure might vary slightly from what is described in this document.

1. Go to http://www.ibm.com/bladecenter/.

2. Click Support.

3. Under Support information, click Product support and information.

4. Under Popular links, click Publications lookup.

5. From the Product family menu, select BladeCenter LS22 or BladeCenter

LS42 and click Go.

Download and install the latest firmware for the management module installed in your BladeCenter unit (see the documentation for your management module).

v Observe good housekeeping in the area where you are working. Put removed

covers and other parts in a safe place.

v Back up all important data before you make changes to disk drives.

v 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.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the blade server, or open or close a latch.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that you can remove or install the component while the BladeCenter unit is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

v When you are finished working on the blade server, reinstall all safety shields,

guards, labels, and ground wires.

v For a list of supported optional devices for the blade server, see

http://www.ibm.com/servers/eserver/serverproven/compat/us/.

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that the following requirements are met:

v Each microprocessor socket always contains either a microprocessor dust cover

and heat sink filler or a microprocessor and heat sink. If the blade server has only one microprocessor, it must be installed in microprocessor socket 1.

v Do not operate the BladeCenter unit without a blade server, expansion unit, or

filler installed in each blade bay. See the documentation for your BladeCenter unit for additional information.

v Make sure that the ventilation holes on the blade server are not blocked.

v The blade server battery must be operational. If the battery becomes defective,

replace it immediately. For instructions, see the Problem Determination and Service Guide.

Handling static-sensitive devices

Attention: Static electricity can damage the blade server and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from 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 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 any unpainted metal surface on any other grounded rack component in the rack in which you are installing the device for at least 2 seconds. This drains static electricity from the package and from your body.

26 BladeCenter LS22 Type 7901 and LS42 Type 7902: Problem Determination and Service Guide

v Remove the device from its package and install it directly into the blade server

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

v Take additional care when you handle devices during cold weather. Heating

reduces indoor humidity and increases static electricity.

Returning a device or component

If you are instructed to return a device or component, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.

Removing the blade server from a BladeCenter unit

The following illustration shows how to remove an LS22 Type 7901 blade server from a Type 8677 BladeCenter unit. The procedure for removing the LS42 Type 7902 blade server and MPE is the same. The appearance of your BladeCenter unit might be different. See the documentation for your BladeCenter unit for additional information.

Release handles (open)

Attention:

v To maintain proper system cooling, do not operate the BladeCenter unit without

a blade server, expansion unit, or filler installed in each blade bay.

v When you remove the blade server, note the bay number. Reinstalling a blade

server into a different bay from the one it was removed from might have unintended consequences. Some configuration information and update options are established according to bay number; if you reinstall the blade server into a different bay, you might have to reconfigure the blade server.

To remove the blade server, complete the following steps:

1. Read the safety information that begins on page “Safety statements” on page

viii and “Installation guidelines” on page 25.

2. If the blade server is operating, shut down the operating system.

3. Press the power-control button (behind the blade server control panel door) to

turn off the blade server (see “Turning off the blade server” on page 6 for more information).

Chapter 4. Removing and replacing blade server components 27

Chapter 5. Diagnostics

This chapter describes the diagnostic tools that are available to help you solve problems that might occur in the blade server.

Note: The blade server uses shared resources that are installed in the BladeCenter unit. Problems with these shared resources might appear to be in the blade server (see “Solving shared BladeCenter resource problems” on page 160 for information about isolating problems with these resources). See the Problem Determination and Service Guide or the Hardware Maintenance Manual and Troubleshooting Guide for your BladeCenter unit and other BladeCenter component documentation for diagnostic procedures for shared BladeCenter components.

If you cannot diagnose and correct a problem by using the information in this chapter, see “Getting help and technical assistance,” on page 167 for more information.

Diagnostic tools

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

v POST beep codes, error messages, and error logs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem. See “POST” for more information.

v Troubleshooting tables

These tables list problem symptoms and actions to correct the problems. See “Troubleshooting tables” on page 89 for more information.

v Light path diagnostics

Use the light path diagnostics to diagnose system errors quickly. See “Light path diagnostics” on page 103 for more information.

v Diagnostic programs, messages, and error codes

The diagnostic programs are the primary method of testing the major components of the blade server. These programs are stored in read-only memory (ROM) on the blade server. See “Dynamic System Analysis diagnostic programs and messages” on page 108 for more information.

POST

When you turn on the blade server, it performs a series of tests to check the operation of the blade server components and some optional devices in the blade server. This series of tests is called the power-on self-test, or POST.

If a power-on password is set, you must type the password and press Enter, when you are prompted, for POST to run.

If POST is completed without detecting any problems, a single beep sounds, and the blade server startup is completed.

If POST detects a problem, more than one beep might sound, or an error message is displayed. See “Beep code descriptions” and “Dynamic System Analysis diagnostic programs and messages” on page 108 for more information.

POST beep codes

A beep code is a combination of short or long beeps or a series of short beeps that are separated by pauses. For example, a “1-2-3” beep code is one short beep, a pause, two short beeps, a pause, and three short beeps. A beep code other than one beep indicates that POST has detected a problem. To determine the meaning of a beep code, see “Beep code descriptions.” If no beep code sounds, see “No-beep symptoms” on page 71.

Beep code descriptions

The following table describes the beep codes and suggested actions to correct the detected problems.

A single problem might cause more than one error message or beep code. When this occurs, correct the cause of the first error message or beep code. The other error messages and beep codes usually will not occur the next time POST runs.

Exception: If multiple error codes or light path diagnostics LEDs indicate a microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See “Microprocessor problems” on page 93 for information about diagnosing microprocessor problems.

v Follow the suggested actions in the order in which they are listed in the Action column until the problem is

solved.

Chapter 5. Diagnostics 71

Error logs

The BMC log contains all system status messages from the blade server service processor. The management-module event log in your BladeCenter unit contains messages that were generated on each blade server during POST and status messages from the BladeCenter service processor. (See the Management Module User’s Guide for more information.)

The following illustration shows an example of a BMC log entry.

---------------------------------------------------------Get Next Entry Get Previous Entry Clear BMC SEL

Entry Number= 00005 / 00011 Record ID= 0005 Record Type= 02 Timestamp= 2005/01/25 16:15:17 Entry Details: Generator ID= 0020

BMC System Event Log

Sensor Type= 04 Assertion Event Fan Threshold Lower Non-critical - going high

Sensor Number= 40 Event Direction/Type= 01

Event Data= 52 00 1A

Important:

v A single problem might cause several error messages. When this occurs, work to

correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the test.

v The management-module event log in your BladeCenter unit lists messages

according to the position of the blade server in the blade server bays. If a blade server is moved from one bay to another, the management-module event log reports messages for that blade server according to the new bay number; messages for that blade server that were generated before the move will still be listed according to the previous bay number.

Attention: Some blade server configuration information and update options are established according to bay number. Reinstalling a blade server into a different blade bay from the one from which it was removed might have unintended consequences, and you might have to reconfigure the blade server. For more information about viewing the management-module event log, see the

Management Module User’s Guide or the Management Module Command-Line Interface Reference Guide. The most recent versions of all BladeCenter

documentation are at http://www.ibm.com/bladecenter/.

The BMC log is limited in size. When the log is full, new entries will not overwrite existing entries; therefore, you must periodically clear the BMC log through the Setup Utility program (the menu choices are described in the Installation and User’s Guide) or through the management-module user interface. When you are troubleshooting an error, be sure to clear the BMC log so that you can find current errors more easily.

72 BladeCenter LS22 Type 7901 and LS42 Type 7902: Problem Determination and Service Guide

Entries that are written to the BMC log during the early phase of POST show an incorrect date and time as the default time stamp; however, the date and time are corrected as POST continues.

Each BMC log entry is displayed on its own page. To display all the data for an entry, use the Up Arrow (↑) and Down Arrow (↓) keys or the Page Up and Page Down keys. To move from one entry to the next, select Get Next Entry or Get Previous Entry.

The BMC log indicates an assertion event when an event has occurred. It indicates a deassertion event when the event is no longer occurring.

Some of the error codes and messages in the BMC log are abbreviated.

You can view the contents of the BMC log from the Setup Utility program and from the diagnostic programs.

When you are troubleshooting PCI-X slots (I/O slots), note that the error logs report the PCI-X buses numerically. The numerical assignments vary depending on the configuration. You can check the assignments by running the Setup Utility program (see the Installation and User’s Guide for more information).

Viewing the BMC log from the Setup Utility program

For more information about using the Setup Utility program, see the Installation and User’s Guide.

To view the BMC log, complete the following steps:

1. Turn on the blade server (see “Turning on the blade server” on page 5).

2. When the prompt Press F1 for Setup is displayed, press F1. If you have set a

power-on password, you must type the password and press Enter to start the Setup Utility program.

3. Select Advanced Settings, select Baseboard Management Controller (BMC)

settings, and then select BMC System Event Log.
