Chapter 3. Customer replaceable units

This chapter provides instructions for installing, removing, and connecting optional devices that the server supports.

Installation guidelines

Before you begin installing options, read the following information:

v Read Appendix B, “Safety information,” on page 129 and the guidelines in

“Handling static-sensitive devices” on page 16. This information will help you work safely with the server and options.

v Make sure that you have an adequate number of properly grounded electrical

outlets for the server, monitor, and other devices.

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

supplies or hot-swap fans.

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

to remove it from or install it in the server, open or close a latch, and so on.

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 if the server and operating system support hot-swap capability, you can remove or install the component while the server 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 For a list of supported options for the server, go to http://www.ibm.com/servers/

eserver/serverproven/compat/us/.

System reliability considerations

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

v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed in it.

v If the server has redundant power, each of the power-supply bays has a power

supply installed in it.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the server cover before turning on the server. Operating the server for extended periods of time (more than 30 minutes) with the server cover removed might damage server components.

v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan within 48 hours. v When replacing a hot plug fan, you have 5 minutes to install the new fan or the

server will shut down.

v You have replaced a hot-swap drive within 2 minutes of removal.

Working inside the server with the power on

The server supports hot-swap devices and is designed to operate safely while it is turned on and the cover is removed. Follow these guidelines when you work inside a server that is turned on:

v Avoid wearing 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 let your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that could fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.

Handling static-sensitive devices

Attention: Static electricity can damage the 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 Wear an electrostatic-discharge wrist strap, if one is available. 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 server 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 server without

setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the server cover or on a metal surface.

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

indoor humidity and increases static electricity.

Hard disk drives

This section describes how to install a hard disk drive in the server. Before you continue with the hard disk drive installation procedures, review “Hard disk drive considerations.”

Hard disk drive considerations

The following notes describe the types of hard disk drives that the server supports and other information that you must consider when installing a hard disk drive:

v The server supports the following three configurations:

– Configuration 1

- Four 2.5-inch hot-swap SCSI hard disk drives

– Configuration 2

- Two 3.5-inch slim hot-swap SCSI hard disk drives

- One 9.5-mm-high DVD-ROM drive (optional)

– Configuration 3

- Two 3.5-inch non-hot-swap (simple swap) Serial ATA (SATA) hard disk drives

- One 9.5-mm-high DVD-ROM drive (optional)

Both SCSI configuration models of the server come with a hot-swap SCSI

backplane.

v The SCSI server models support low voltage differential (LVD) hot-swap drives.

Each hot-swap drive is in a tray, which has a green activity LED and an amber status LED in the upper-right corner. These LEDs are lit if the drive is active and, in some cases, if the drive fails.

26 xSeries 336 Type 1879 and Type 8837: Hardware Maintenance Manual and Troubleshooting Guide

v Each hot-swap drive has a single-connector-attached (SCA) connector, which

connects directly to the hot-swap SCSI backplane. The backplane attaches to connector J-35 on the system board and controls the SCSI IDs for the hot-swap drives.

v A simple swap disk drive does not have a backplane, and it does not have

indicator LEDs. Simple swap disk drives have a panel-mount connection at the rear of the hard disk drive cage, which enables the simple swap disk drives to easily connect to both the signal and power connections.

v Before you install any type of hard disk drive, read the following information:

– Inspect the drive tray for signs of damage before inserting the hard disk drive. – Read Appendix B, “Safety information,” on page 129 and “Installation

Memory modules

This section provides information on the types of memory modules the server supports, and describes how to install memory modules.

Memory module considerations

This section contains information that you must consider when installing DIMMs:

v The server supports up to eight PC3200 DDR II ECC Registered SDRAM DIMMs

in sizes ranging from 256 MB to 2 GB. The minimum memory size is 512 MB. The maximum supported memory size is 16 GB.

v The server supports 256 MB, 512 MB, 1 GB, and 2 GB DIMMs. See the

ServerProven® list at http://www.ibm.com/servers/eserver/serverproven/compat/ us/ for a list of memory modules that the server supports.

v The server comes with one pair of DIMMs installed in DIMM slots 1 and 2 on the

system board. The server comes with either 512 MB (two 256 MB DIMM) for the

2.8GHz models or 1GB (two 512MB DIMM) for all other models.

v The server uses interleaved DIMMs; you must add, remove, or replace DIMMs in

pairs. Each pair must be of the same type, capacity, and speed.

32 xSeries 336 Type 1879 and Type 8837: Hardware Maintenance Manual and Troubleshooting Guide

v You can increase the amount of memory in the server by replacing them with

higher-capacity DIMMs or installing an additional pair of DIMMs into the remaining slots. Figure 25 shows the memory slots on the system board.

Slot 8

Slot 1

Figure 25. Memory module installation

Note: When installing additional DIMMs, always install in pairs starting with slots

1 and 2.

v The server supports Chipkill™ memory technology, which enables the server to

function with one bad chip on a DIMM. The bad memory module must be on an x4 DIMM. The 256 MB and 512 MB DIMMs that are x8 DIMMs do not support Chipkill memory (see Table 1).

Table 1. Supported Chipkill memory configurations

v You can configure the server to use memory mirroring. Memory mirroring stores

data in two pairs of DIMMs simultaneously. When using memory mirroring, you must install two pairs of DIMMs at a time. All the DIMMs you use in memory mirroring must be identical. See Table 2 for the DIMM pairs that are in each pair.

Note: The use of memory mirroring decreases the amount of available memory

by half.

Table 2. Memory mirroring DIMM installation sequence

Table 2. Memory mirroring DIMM installation sequence (continued)

Pair DIMM pairs

3 Slots 5 and 6 4 Slots 7 and 8

v The server also supports memory sparing; however, the sparing feature is

mutually exclusive with mirroring. The sparing feature disables the failed memory from the system configuration and activates a memory sparing pair of DIMMs to replace the failed active DIMM pair.

Before you can enable the memory sparing feature, you must install one additional pair of DIMMs. The memory sparing DIMM pair must be the same speed, type, and the same size as or larger than the active DIMM pair.

To enable memory mirroring or sparing 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 the User’s Guide on the IBM Documentation CD. See Table 3 for memory-sparing DIMM connector assignments.

v If you install a second microprocessor in the server, microprocessor 1 is installed

in microprocessor socket 1 (U16), and microprocessor 2 is installed in socket 2 (U32).

You must also install the following items that come with the second microprocessor:

– Voltage regulator module (VRM), which you plug into VRM connector J25 – Cooling fan, which you plug into fan position 4

Notes:

1. Read the documentation that comes with the microprocessor to determine whether you must update the basic input/output system (BIOS) code. The most current level of BIOS code for the server is available at http://www.ibm.com/ support/.

2. A new microprocessor comes in a kit with a VRM, cooling fan, and a heat sink.

36 xSeries 336 Type 1879 and Type 8837: Hardware Maintenance Manual and Troubleshooting Guide

3. To use SMP, obtain an SMP-capable operating system (optional). For a list of supported operating systems, go to http://www.ibm.com/servers/eserver/ serverproven/compat/us/.

Attention: To avoid damage and to ensure proper server operation, review the

following information before you install a microprocessor:

v Make sure that the microprocessors are the same type, have the same cache

size, and have the same clock speed.

v Make sure that the microprocessor internal and external clock frequencies are

identical.

v See the ServerProven list at http://www.ibm.com/servers/eserver/serverproven/

compat/us/

for a list of microprocessors that the server supports.

Installing a microprocessor

Complete the following steps to install a microprocessor:

1. Read Appendix B, “Safety information,” on page 129 and “Installation guidelines” on page 15.

2. Turn off the server and peripheral devices (see “Turning off the server” on page 10); then, and disconnect all power cords and external cables.

3. Remove the server cover.
