Active Memory

Active Memory is an IBM feature that improves the reliability of memory through hot-swap memory, memory mirroring, memory scrubbing, and the Memory ProteXion feature.

Memory scrubbing and Memory ProteXion

Memory scrubbing tests the memory at regular intervals to detect and report recoverable memory ECC errors before they can cause server outages.

If the recoverable ECC error rate exceeds the system-defined threshold, the Memory ProteXion feature replaces the failing bit positions, maintaining reliable operation. If the recoverable ECC error rate exceeds the threshold again, light path diagnostics LEDs are lit to indicate the failing DIMM.

You do not have to enable memory mirroring to use memory scrubbing and the Memory ProteXion feature.

Memory mirroring

Memory mirroring stores data in memory port 1 and memory port 2 simultaneously. To support memory mirroring, you must install identical dual inline memory modules (DIMMs) in memory port 1 and memory port 2. For more information, see the section about installing memory modules in the Option Installation Guide on the IBM

xSeries Documentation CD.

To enable memory mirroring through the Configuration/Setup Utility program, select Advanced Setup from the main menu, and select Memory Configuration. For more information about using the Configuration/Setup Utility program, see Chapter 2, “Configuring the server,” on page 11.

Hot-swap memory

You can replace a failed DIMM while the server is turned on, provided that you have enabled memory mirroring and that you have installed all DIMMs in the sequence to support memory mirroring.

If a problem with a DIMM is detected, light path diagnostics LEDs are lit to indicate the failing DIMM. When this occurs, identify the defective DIMM, and then remove and replace the DIMM. For more information, see the information about installing memory modules in the Option Installation Guide on the IBM xSeries

Documentation CD.

If continue with “Using the ASM interconnect network.” If you do not want to set up an ASM interconnect network, Remote Supervisor Adapter configuration is now complete. To start managing the server remotely, see the Remote Supervisor

Adapter User’s Guide on the IBM xSeries Documentation CD.

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 requiring additional communications hardware or network interface adapters.

An 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 on the network are. 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 an alert and must forward the information to another one of these devices to send the alert.

Planning and cabling the interconnect network

To 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.

Chapter 2. Configuring the server 29

Note: To ensure the stability of the system, the most current level of firmware must

be 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 from http://www.ibm.com/pc/support. For more information about updating firmware, see 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 455 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 connect the ASM Interconnect module to the Remote Supervisor Adapter Ethernet connector.

To connect the servers, note the following setup and configuration information:

v Make sure 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.

v Make sure that the total combined length of all Ethernet cables connecting the

server in the ASM interconnect network does not exceed 91 m (300 ft).

v Each Remote Supervisor Adapter, ASM PCI adapter, or ASM processor that is

connected to the ASM interconnect network bus counts as one connection. For 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 systems-management information. This section provides information about 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 modems or Ethernet connections 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.

If there are multiple modems or network connections 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

30 IBM xSeries 455 Type 8855: Hardware Maintenance Manual and Troubleshooting Guide

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 only once (per connection type), but an alert is forwarded to another interconnect device if the resources are 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 scenario might occur:

If ASM processor 1 generates an alert and the modem is disconnected from ASM processor 2 within 45 seconds before ASM processor 1 generates 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 upon 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 455 server

The ASM Interconnect module connects the Remote Supervisor Adapter to the ASM interconnect network. Yo u must purchase this module separately. To connect the ASM interconnect module to the Remote Supervisor Adapter, complete the following steps.

Attention: To avoid damage to the Ethernet connector, do not connect the ASM

interconnect module into the Remote Supervisor Adapter Ethernet connector.

1. Connect the ASM Interconnect module 1 to the Remote Supervisor Adapter ASM interconnect (peer-to-peer) connector 2 as shown in the following illustration. This connector is on the edge of the Remote Supervisor Adapter that is accessible from the rear of the server and is labeled “RS485”.

Chapter 2. Configuring the server 31

2. Connect one or two Category 3 or Category 5 Ethernet cables to the other end of the ASM Interconnect module.

Configuring the Gigabit Ethernet controller

The Ethernet controller is integrated on the system board. It provides an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provides 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 controller detects the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operates at that rate and mode.

Chapter 3. Diagnostics

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

If you cannot locate and correct the problem using the information in this section, see Appendix A, “Getting help and technical assistance,” on page 213 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.

If 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.

A 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.

A server might be part of a cluster if:

v The server is identified as part of a cluster. v 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.

v One or more servers are located near the failing server.

If 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:

1. 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.

2. If multiple error codes are displayed, diagnose the first error code that is displayed.

3. If the server stops with a POST error, see “SAL/EFI messages” on page 163.

4. If the server stops and no error is displayed, see “Undetermined problems” on page 205.

5. For power supply problems, see “Power checkout” on page 74.

6. For safety information, see “Safety information” on page 215.

7. For intermittent problems, check the system-error log.

Follow the steps in this procedure to identify system problems.

Diagnostic tools overview

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

v POST error messages

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

v System-error logs

The system-error log contains all the error messages that were issued during POST. See “System-error logs” on page 40.

v Light Path Diagnostics feature

Use the Light Path Diagnostics feature to identify system errors quickly (see “Light Path Diagnostics feature” on page 40).

v Diagnostic display

If a problem is detected with system power on or during initialization, an error code might be present in the two-hex character diagnostic display on the midplane board. See “Diagnostic display error codes” on page 201 for more information.

v Diagnostic programs and error messages

The AMIDiag program is the primary method of testing the major components of the server. The AMIDiag program is stored in the EEPROM on the I/O board. Yo u 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 42 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.

v 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:

1. This server does not produce beep codes.

2. 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 163 for more information.

Chapter 3. Diagnostics 39

System-error logs

The system-error log contains all messages issued during system initialization or normal system operation.

You can view the contents of the system-error log from the Configuration/Setup Utility program or from the service processor. To view error logs from the Configuration/Setup Utility program, start the Configuration/Setup Utility program; then, select Error Logs from the main menu. See “Starting the Configuration/Setup Utility program” on page 12 for more information.

You can also use the error-log viewer in the AMIDiag program. For information about viewing diagnostic program error logs from the AMIDiag program, see “Error-log viewer” on page 46.

Light Path Diagnostics feature

The Light Path Diagnostics panel is inside the Light Path Diagnostics drawer on the front right of the server. To access the light path diagnostics panel, press on the front of the panel.

The following illustration shows the location of the diagnostics panel. See “The diagnostics panel” on page 41 for information about identifying problems using the Light Path Diagnostic LEDs.

40 IBM xSeries 455 Type 8855: Hardware Maintenance Manual and Troubleshooting Guide

The system-error LED on the operator information panel is lit when certain system errors occur. If the system-error LED on the server is lit, one or more LEDs inside the server might be lit. Use the Light Path Diagnostics panel to identify the type of error that occurred, and see “Light Path LED errors” on page 159 to help determine the cause of the error and the action you should take.

To view the LEDs on the various main boards, look at the board indicated by the diagnostic panel.

To acknowledge a system error but not take immediate action, press the REMIND button, and place the Light Path Diagnostics feature in Remind mode. The system-error LED flashes in Remind mode. If a new failure occurs, the system-error LED is lit again.

The diagnostics panel

The diagnostics panel should be the first place you look for help with identifying problems. If a system error occurs, the system-error LED on the front of this panel is lit. Press the front of the panel to open the diagnostics panel, and look for any lit LEDs. These lit LEDs can help you identify the possible cause of the error. Make a note of any LEDs that are lit, and then close the panel.

LEDs on the top of the server

You can also use the LEDs on the top of the server to find an error. If the BOARD LED on the diagnostics panel is lit, pull the server out, and view the top cover. In the center of the top cover is a set of six LEDs and the system service labels. The numbers next to the LEDs correspond to the numbers on the system service label. Note the lit LED, and see the numbered block on the system service label that corresponds to the lit LED. Then, follow the instructions, if any, in the numbered block.

LEDs on the system boards

To locate the actual component that caused the error, locate the lit LED next to that component.

For example:

A 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 129. 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 131 and “Installing and replacing a microprocessor and power module” on page 99 to remove and replace the microprocessor.

For more information about LEDs and connectors, see “Major components of the xSeries 455 server” on page 79.

Chapter 3. Diagnostics 41

Diagnostic display

If a problem is detected with system power on or during initialization, the two-hex character diagnostic display on the midplane board might show an error code. See “Midplane board LEDs” on page 80 and “Diagnostic display error codes” on page 201 for more information.

Diagnostic programs, error codes, and messages

Diagnostic error messages indicate that a problem exists. They are not intended to be 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 159 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

is 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:

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:

1. Turn off the server, and disconnect all ac power cords.

2. 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.

74 IBM xSeries 455 Type 8855: Hardware Maintenance Manual and Troubleshooting Guide

3. 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 on page 200).

4. 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.

To 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 205).

Troubleshooting the Ethernet controller

If a 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 71. For information about the Ethernet error codes and actions to take, see the documentation on the Resource CD.

Network connection problems

If the Ethernet controller cannot connect to the network, check the following conditions:

v 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.

If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps, you must use Category 5 or higher cabling.

v 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.

v 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 a defective connector or cable or a problem with the hub.

v Make sure that you are using the correct device drivers, which are supplied with

your server.

v Check for operating-system-specific causes for the problem. v Make sure that the device drivers on the client and server are using the same

protocol.

v 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).

controller to match the hub.

v If you manually configured the Duplex mode, make sure that you also

manually configure the speed.

v Reseat or replace the adapter.

Check the following:

v Make sure that you have loaded the network device drivers. v The network might be idle. Try sending data from this server.

v Make sure that you are using Category 5 or higher cabling when operating the

server at 100 Mbps or at 1000 Mbps.

v Make sure that the cables do not run close to noise-inducing sources like

fluorescent lights.

Ethernet controller messages

The integrated Ethernet controller might display messages from certain device drivers. The latest information available concerning these messages will be made available at the IBM Support Web site at http://www.ibm.com/eserver/xseries.

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:

v Read the safety information beginning on page 215 and the guidelines in

“Handling static-sensitive devices” on page 78. This information will help you work safely with your server or options.

v 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.

v Back up all important data before you make changes to disk drives. v You do not need to turn off the server to install or replace hot-swap or hot-plug

components, or hot-plug Universal Serial Bus (USB) devices.

v The orange color on components and labels identifies hot-swap or hot-plug

components. You can install or remove hot-swap and hot-plug components while the server is running, provided that the server is configured to support this capability. See the instructions in this chapter for more information about removing and installing hot-swap and hot-plug components.

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

http://www.ibm.com/pc/us/compat/.

Some preconfigured servers have a unique list of supported options. See the

Note:

software documentation provided with those servers for more information.

System reliability considerations

To help ensure proper cooling and system reliability, make sure that:

v The top cover is closed during normal operation. v Each of the drive bays has either a drive or a filler panel installed. v There is space around the server to allow the cooling system to work properly. v Cables for optional adapters are routed according to the instructions that are

provided with the adapters.

v All microprocessors have the same cache size and type and the same clock

speed.

v For proper cooling, do not leave the cover open for more than 15 minutes. v A failed fan is replaced within 48 hours. v The top cover is closed during normal operation. v Do not remove a defective power supply until a replacement is available. v For redundant and hot-swappable operation, the power supplies are connected to

200-240 V ac.

v If you replace a hot-swap drive, remove the defective drive and wait 15 seconds

before you install a new drive.

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:

v 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.

v Do not allow your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, rings, necklaces, and loose-fitting wrist

watches.

v Remove items from your shirt pocket (such as pens or pencils) that could fall into

the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hair pins, or screws,

into the server.

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.

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 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.

v 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 in to its static-protective package. Do not place the device on your system unit cover or on a metal surface.

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

indoor humidity and increases static electricity.

v Wear a properly grounded wrist strap against your skin to help eliminate static

electricity from your body.

Installing an adapter

The following notes describe the types of adapters that your server supports and other information that you must consider when installing an adapter:

v The following illustration shows the location and bus speeds of the PCI-X

expansion slots on the PCI-X board.

PCI-X slot 6 (133 MHz)

PCI-X slot 5 (133 )MHz

PCI-X slot 4 (100 )MHz

PCI-X slot 3 (100 )MHz

PCI-X slot 2 (66 )MHz

Attention LED Power LED

PCI-X slot 1 (66 )MHz

v Locate the documentation that comes with the adapter, and follow those

instructions in addition to the instructions in this section. If you need to change the switch settings or jumper settings on your adapter, follow the instructions that come with the adapter.

v Video adapters are not supported. v Some full-length adapters have extension handles or brackets installed. Before

installing the adapter, you must remove the extension handle or bracket.

v Your server supports six hot-plug 64-bit adapters in the expansion slots on the

PCI-X board. The PCI device mapping for the xSeries 455, including attached RXE-100s, is

shown in the following tables. Actual bus numbers are obtained by adding the bus number offset associated with each node to the bus number indicated in the device mapping table.

RXE-100 PCI slot 12 (100 MHz*) 2 AD18 * 133 MHz operation with only one adapter installed on this PCI bus at system power on.

v You can install both PCI and PCI-X adapters on the same bus. However, if you

install a PCI adapter and a PCI-X adapter on the same bus, the PCI-X features of the PCI-X adapter will be disabled, and the adapter will function as a PCI adapter.

v You can install PCI or PCI-X adapters of speeds faster than what is labeled for a

particular PCI-X bus. For example, if you install two 133 MHz adapters into slots that are labeled as 100 MHz slots, the adapters will operate at 100 MHz.

v If you install a 33 MHz and a 66 MHz adapter on the same bus, the bus speed

will match that of the slowest adapter.

v If a single 133 MHz adapter is installed on PCI-X bus B (slots 3 and 4) and the

other slot on PCI-X bus B is empty, the adapter will operate at 133 MHz.

v The server scans PCI-X slots in the following order: the xSeries 455 integrated

devices are scanned first; then, PCI-X slots 1, 2, 3, 4, 5, and 6. If an RXE-100 enclosure is attached to an xSeries 455 server, the scan order is as follows: the xSeries 455 integrated devices are scanned first; then, PCI-X slots 1, 2, 3, 4, 5, and 6; then, the RXE-100 slots 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.

v Your server supports 3.3 V and universal adapters; it does not support 5.0 V

adapters.

Chapter 4. Installing options 89

Complete the following steps to install an adapter:

1. Read the safety information beginning on page 215 and “Installation guidelines” on page 77.

Attention: When you handle static-sensitive devices, take precautions to

avoid damage from static electricity. For details about handling these devices, see “Handling static-sensitive devices” on page 78.

2. Disable the PCI-X slot through your operating system before you insert or remove a PCI or PCI-X adapter.

Note: Some operating systems do not support the enabling and disabling of a

PCI-X slot. If your operating system does not support this function, turn off the server and peripheral devices, and disconnect the power cords and all external devices from the back of the server before proceeding.

3. Open the top cover.

4. Follow the cabling instructions, if any, that come with the adapter. Route the adapter cables before you install the adapter.

5. Follow the instructions that come with the adapter to set jumpers or switches, if any.

6. Install the adapter:
