Using the ASM interconnect network

This section explains how to configure and connect the server to function within an ASM interconnect network.
The ASM interconnect network can include as many as 12 individual ASM connections in a single bus. These connections can include Remote Supervisor Adapters, ASM processors, and ASM PCI adapters. When the clients and servers are connected, they use the ASM interconnect network to share ASM resources, information, and alerts among multiple servers without having to add additional communications hardware or network interface adapters.
ASM interconnect network provides two levels of functionality. First, the ASM interconnect network enables you to configure settings and to control the servers where other Remote Supervisor Adapters, ASM processors, and ASM PCI adapters
the network reside. Second, the ASM interconnect network enables other interconnect network devices to use the resources (Ethernet or modem) of other Remote Supervisor Adapters, ASM processors, and ASM PCI adapters in the ASM interconnect network for sending alerts. This interconnect network is used when Remote Supervisor Adapters, ASM processors, or ASM PCI adapters cannot send
alert and must forward the information to another one of these devices to send the alert.
Planning and cabling the interconnect network
support the most recent ASM features, a Remote Supervisor Adapter must be the main gateway interconnect to the ASM interconnect bus if the bus also includes servers with ASM PCI adapters or ASM processors. The Remote Supervisor Adapter forwards the ASM information generated by the servers attached to the ASM interconnect bus to other servers on the Ethernet network. The connected ASM processors and ASM PCI adapters are managed through the new user interface and Web browser access of the Remote Supervisor Adapter.
Note: To ensure the stability of the system, you must have the most current level of
firmware installed on the Remote Supervisor Adapter that is the main interconnect gateway for the ASM interconnect network. The most current level of firmware is available at http://www.ibm.com/pc/support/ on the World Wide Web. For more information about updating firmware, see “Updating the firmware” on page 39 and the Remote Supervisor Adapter User’s Guide on the IBM xSeries Documentation CD.
You must connect an ASM Interconnect module to the Remote Supervisor Adapter and to each xSeries 450 server that you connect to the ASM interconnect network bus.
Attention: To avoid damage to the Ethernet connector on the Remote Supervisor
Adapter, do not plug the ASM Interconnect module into the Remote Supervisor Adapter Ethernet connector.
connect the servers, note the following setup and configuration considerations:
Ensure that the ASM interconnect network is set up as a bus topology. You must connect the servers to the ASM interconnect network in a series, with terminated beginning and end points.
Ensure that the total combined length of all Ethernet cables connecting the server in the ASM interconnect network does not exceed 91 m (300 ft).
Each Remote Supervisor Adapter, ASM PCI adapter, or ASM processor that is connected to the ASM interconnect network bus counts as one connection. For
IBM xSeries 450 Type 8688: Hardware Maintenance Manual and Troubleshooting Guide
If
If
example, if an ASM PCI adapter is installed in a server that has an ASM processor, the processor and the adapter connect to each other using one ASM interconnect connection, but the processor and the adapter count as two connections on the ASM interconnect network bus.
Forwarding alerts
Remote Supervisor Adapters, ASM PCI adapters, and ASM processors that are connected to an ASM interconnect network share resources and system-management information. This section provides information on how alerts are forwarded in the ASM interconnect network.
During normal operation, each Remote Supervisor Adapter, ASM processor, or ASM PCI adapter on the ASM interconnect network communicates with the other processors and adapters on the network. Processors or adapters that have a modem or Ethernet connection notify the other processors and adapters that these communications resources are available for use by other servers on the ASM interconnect network. These resources are then used as ASM interconnect network resources, enabling Remote Supervisor Adapters, ASM processors, or ASM PCI adapters on the ASM interconnect network to send alerts using a modem or the network, even if they do not have a modem or network connection physically attached.
When alerts are generated, they are forwarded to the Remote Supervisor Adapter, ASM processor, or ASM PCI adapter on the ASM interconnect network that has the communication resources to forward the alert. If no system on the ASM interconnect network meets the requirements, the alert is set for transmission if the connection type is configured or becomes available later.
multiple modems or network connections exist in the ASM interconnect network, you cannot specify which system will receive an alert or which will use its modem or network connection to forward the alert. If an alert is forwarded to a Remote Supervisor Adapter, ASM processor, or ASM PCI adapter that is unable to deliver the alert (for example, the modem it is configured to use has failed or the network cannot resolve the destination IP address), the processor or adapter attempts to forward the alert to another system on the ASM interconnect network that has the communication resources to forward the alert.
Alerts are typically sent once per connection type, but an alert is forwarded to another interconnect device if the resources exist on other interconnect devices in the network. For example, on a three ASM processor network where ASM processor 1 generates a modem alert, but does not have a modem and the other ASM processors have modems, the following might occur:
ASM processor 1 generates an alert and the modem is unplugged from ASM processor 2 45 seconds prior to ASM processor 1 generating the alert, ASM processor 1 forwards the alert to ASM processor 2, having previously determined that ASM processor 2 has an available modem. When ASM processor 2 receives the forwarded alert, it determines that a modem is attached to ASM processor 3 and forwards the alert. Therefore, depending on the time frame (45 seconds) within which a resource (modem) fails, the alert might be forwarded multiple times until an interconnect device can send the alert.
Connecting the ASM Interconnect module to the xSeries 450
The ASM Interconnect module connects the Remote Supervisor Adapter to the ASM interconnect network. This module must be purchased separately.

Configuring the Gigabit Ethernet controller

The Ethernet controllers are integrated on the I/O board. They provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in your server support auto-negotiation, the controllers detect the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operate at that rate and mode.
You do not need to set any jumpers or configure the controllers. However, you must install a device driver to enable the operating system to address the controllers. For device drivers and information about configuring the Ethernet controllers, see the
Resource CD that comes with your server. For updated information about
configuring the controllers, go to http://www.ibm.com/pc/support/ on the World Wide Web.

This section provides basic troubleshooting information to help you resolve some common problems that might occur with your server.
you cannot locate and correct the problem using the information in this section, see Appendix A, “Getting help and technical assistance,” on page 195 for more information.

General checkout

The server diagnostic programs are stored in the upgradeable electronically erasable programmable read-only memory (EEPROM) on the I/O board and on the
Resource CD. These programs provide the primary methods of testing the major
components of the server.
you cannot determine whether a problem is caused by the hardware or by the software, run the diagnostic programs to confirm that the hardware is working properly.
Note: 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.
failed server might be part of a shared hard disk drive cluster (two or more servers sharing one or more external storage devices). Before you run diagnostics, verify that the failing server is not part of a shared storage device cluster.
server might be part of a cluster if:
The server is identified as part of a cluster. One or more external storage units are attached to the server and at least one of
the attached storage units is also attached to another server or unidentifiable source.
One or more servers are located near the failing server.
the failing server is suspected to be part of a shared hard disk drive cluster, run all diagnostic tests except those that test the storage unit (storage device residing in the storage unit) or the storage adapter attached to the storage unit.
Notes:
For servers that are part of a shared hard disk drive cluster, run one test at a time in looped mode. Do not run all tests in looped mode, because this could enable the hard disk drive diagnostic tests.
multiple error codes are displayed, diagnose the first error code that is
displayed.

You can download the latest version of this program and copy it to a CD so that you can update the AMIDiag program. See “Starting the AMIDiag program” on page
for more information.
The diagnostic program for the Ethernet controller is on the Resource CD. For instructions about using this CD, see “Troubleshooting the Ethernet controller” on page 75.
Product support page
The IBM Web site has up-to-date information about IBM xSeries products, services, and support at http://www.ibm.com/eserver/xseries/ on the World Wide Web.
You can find service information for your IBM products, including supported options, at http://www.ibm.com/pc/support/.

POST error codes and messages

When you turn on the server, it performs a series of tests to check the operation of server components and some of the options installed in the server. This series of tests is called the power-on self-test, or POST.
Notes:
This server does not produce beep codes. Depending on system configuration, POST might run for several minutes before
the video console is enabled. During this time, POST operation is indicated by the flashing blue locator LED on the front panel. Diagnostic display error codes track the startup progress until video is enabled.
POST finishes without detecting any problems, the EFI Boot Manager screen
If appears. If POST detects a problem, an error message will be sent to either the serial port or the display screen. See “SAL/EFI messages” on page 150 for more information.

For example:
system error has occurred, and you have noted that the CPU LED is lit on the diagnostics panel. Referring to the LEDs on the top cover, you see that LED 2 is lit. You then locate the panel on the system service label with the number 2 on it. In this case, the instructions in the panel tell you that the problem occurred with one of the microprocessors. Follow the instructions to remove the processor-board assembly. See “Processor-board assembly” on page 119. Located on the circuit board is the light-path capacitor switch. Press and hold the switch until you locate the lit LED next to the defective microprocessor. Follow the instructions in “Microprocessor and power module” on page 121 and “Installing and replacing a microprocessor and power module” on page 100 to remove and replace the microprocessor.

Diagnostic programs, error codes, and messages

Diagnostic error messages indicate that a problem exists. They are not intended to
used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.
Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears.
Chapter 6, “Symptom-to-FRU index,” on page 147 contains the error codes that might appear in the detailed test log and summary log when the diagnostic programs are run.

Text messages

The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
the name of the function being tested when the error occurred. This corresponds to the function code (fff) shown in the error code format in the previous section.
Result
can be one of the following:
Passed
Failed
Aborted

Starting the AMIDiag program

The AMIDiag program is stored in the EEPROM of the server. You can download the latest version from http://www.ibm.com/eserver/xseries/ on the World Wide Web.
Starting the AMIDiag program from the server
Complete the following steps to start the AMIDiag program:
Turn on the server, and watch the screen.
This result occurs when the diagnostic test is completed without any errors.
This result occurs when the diagnostic test discovers an error.
This result occurs when you stop the diagnostic test before
complete.
Note: To run the AMIDiag program, you must start the server with the highest

Power checkout

Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition.
Follow this general procedure for troubleshooting power problems:
Turn off the server, and disconnect all ac power cords. Check for loose cables in the power subsystem. Also check for short circuits; for
example, a loose screw might be causing a short circuit on a circuit board. Remove adapters and disconnect the cables and power connectors to all
internal and external devices until the server is at the minimum configuration required to start the server (see the note about minimum operating requirements
page 180).
Reconnect all ac power cords, and turn on the server. If the server starts successfully, replace adapters and devices one at a time until the problem is isolated. If the server does not start up from the minimal configuration, replace FRUs of the minimal configuration one at a time until the problem is isolated.
use this method, it is important to know the minimum configuration required for a system to start (see the minimum configuration requirements at “Undetermined problems” on page 185).

Troubleshooting the Ethernet controller

problem occurs with the 10/100/1000 Mbps Ethernet controller, use the Ethernet diagnostic program on the Resource CD to diagnose the problem. For more information about this CD, see “Ethernet diagnostic tests” on page 70. For information about the Ethernet error codes and actions to take, see the documentation on the Resource CD.

Network connection problems

the Ethernet controller cannot connect to the network, check the following
conditions:
Make sure that the cable is installed correctly. The network cable must be securely attached at all connections. If the cable is
attached but the problem remains, try a different cable.
you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps, you must use Category 5 or higher cabling. Determine whether the hub supports auto-negotiation. If it does not, try configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub. Check the Ethernet controller LEDs on the rear of the server.
These LEDs indicate whether a problem exists with the connector, cable, or hub.
The Ethernet transmit/receive activity LED on the rear of the server is lit when the Ethernet controller sends or receives data over the Ethernet network. If the Ethernet transmit/receive activity LED is off, make sure that the hub and network are operating and that the correct device drivers are installed. The Ethernet link status LED on the rear of the server is lit when the Ethernet controller receives a LINK pulse from the hub. If the LED is off, there might be
defective connector or cable or a problem with the hub.
Make sure that you are using the correct device drivers, which are supplied with
v
your server. Check for operating-system-specific causes for the problem. Make sure that the device drivers on the client and server are using the same protocol. Test the Ethernet controller.
The way the Ethernet controller is tested depends on which operating system you are using (see the Ethernet controller device driver README files).

Chapter 4. Installing options

This chapter provides detailed instructions for installing hardware options in your server.

Installation guidelines

Before you begin to install options in your server, read the following information:
Read the safety information beginning on page 197 and the guidelines in “Handling static-sensitive devices” on page 78. This information will help you work safely with your server or options.
Make sure that you have an adequate number of properly grounded electrical outlets for your server, monitor, and any other devices that you will connect to the server.
Back up all important data before you make changes to disk drives. For a list of supported options for your server, go to
http://www.ibm.com/pc/us/compat/.
Note:
Some preconfigured servers have a unique list of supported options. See the software documentation provided with those servers for more information.

System reliability considerations

help ensure proper cooling and system reliability, make sure that: Each of the drive bays has either a drive or a filler panel installed. There is space around the server to allow the cooling system to work properly. Cables for optional adapters are routed according to the instructions that are
provided with the adapters. All microprocessors have the same cache size and type and the same clock
speed. For proper cooling, do not leave the cover open for more than 15 minutes.
failed fan is replaced within 48 hours.
The top cover is closed during normal operation.
not remove a defective power supply until a replacement is available.
For redundant and hot-swappable operation, the power supplies are connected to 200-240 V ac.

Working inside a server with power on

Your server supports hot-swap devices and is designed to operate safely while turned on with the cover removed. Follow these guidelines when you work inside a server that is turned on:
Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the server; do not wear cuff links while you are working inside the server.
not allow your necktie or scarf to hang inside the server.
Remove jewelry, such as bracelets, rings, necklaces, and loose-fitting wrist watches.

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 package until you are ready to install them.
reduce the possibility of electrostatic discharge, observe the following
precautions:
Limit your movement. Movement can cause static electricity to build up around you.
Handle the device carefully, holding it by its edges or its frame.
not touch solder joints, pins, or exposed printed circuitry. not leave the device where others can handle and damage it.
While the device is still in its anti-static package, touch it to an unpainted metal part of the system unit for at least 2 seconds. This drains static electricity from the package and from your body.
Remove the device from its package, and install it directly into the system unit without setting down the device. If it is necessary to set down the device, place it
its static-protective package. Do not place the device on your system unit
cover or on a metal surface. Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity. Wear a properly grounded wrist strap against your skin to help eliminate static
electricity from your body.

Major components of the xSeries 450 server

The orange color on components and labels in the server indicates hot-swap or hot-plug components. You can install or remove these components while the server
running, provided that the server is configured to support hot-swap and hot-plug
