Chapter 2. Installing options

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

Installation guidelines

Before you begin installing options in your server, read the following information:

v Read the safety information beginning on page v, and the guidelines in “Handling

static-sensitive devices”. This information will help you work safely with your

server and options.

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

outlets for your server, monitor, and other devices that you will connect to the

server.

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

v Have a small Phillips screwdriver available.

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

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

System reliability guidelines

To help ensure proper system 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 Space is available around the server to allow the server cooling system to work

properly. See the documentation that comes with the rack.

v You have followed the cabling instructions that come with optional adapters.

v You have replaced a failed fan as soon as possible.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices, including your server.

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 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, place it back

into its static-protective package. Do not place the device on your 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.

Press in on the USB option tray (below hard disk drive bay 1) to release it and
slide the tray out until it stops; then, press the retention clip at the bottom rear
of the tray and remove the tray from the server.

Note: You need to remove the USB option tray and the bezel only if you are

installing a non-hot-swap hard disk drive. It is not necessary if you are
installing other options in the server.

6. Press on the bezel retention tabs on the top, right side and bottom of the server,
and pull the bezel directly away from the server.

12 IBM xSeries 335 Type 8676: Option Installation Guide

Working with adapters

This section describes how to install an adapter in the server. Before you install an
adapter, review the following information:

v Read the documentation that comes with your operating system.

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

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

v The server comes with two 64-bit 100 MHz peripheral component

interconnect-extended (PCI-X) adapter expansion slots on the system board. The
server is designed specifically for PCI-X adapter support, but it also supports PCI
adapters.

v The expansion slots support both 32-bit and 64-bit adapters. You can install

half-length adapters in slot 1. You can install full-length adapters in slot 2.

v The server supports 3.3 V and universal PCI and PCI-X adapters; it does not

support 5.0 V-only adapters.

v PCI-X slot 2 and the integrated SCSI controller are on PCI-X bus A (bus 1). The

integrated Ethernet controllers are on PCI-X bus B (bus 2). The integrated video
controller is on PCI bus C (bus 0). PCI-X slot 1 is switchable between PCI-X bus
B and PCI bus C by means of the jumper on jumper block J12.

Note: If no jumper is installed on jumper block J12, the server determines

automatically the optimal bus to which to attach PCI-X slot 1. If you install
a jumper between pins 1 and 2 on J12, PCI-X slot 1 is forced to PCI bus
C. If you install the jumper between pins 2 and 3 on J12, PCI-X slot 1 is
forced to PCI-X bus B.

If you force slot 1 to bus B and you install an adapter that runs at less
than 100 MHz in the slot, the integrated Ethernet controllers are forced to
run at the slower speed.

v The server scans PCI-X slots 1 and 2 to assign system resources. By default,

the server starts (boots) devices in the following order: system IDE and SCSI
devices; then, PCI and PCI-X devices.

Note: To change the boot precedence for PCI and PCI-X devices you must

disable the devices through the Configuration/Setup Utility program. Start
the Configuration/Setup Utility program and select Start Options from the
main menu. Then, select the Startup Sequence Options and use the
arrow keys to specify the startup order.

v If you plan to install either an optional SCSI adapter or an optional RAID adapter,

you can install it in either of the PCI-X slots if the size of the adapter permits.
The server supports a variety of RAID adapters for both internal and external
configurations. For the most current list of supported RAID adapters, go to
http://www.ibm.com/pc/us/compat/ on the World Wide Web. For details about
installing a RAID adapter, see the documentation that comes with the adapter.

v If you plan to use a RAID adapter to control internal hot-swap hard disk drives,

disconnect the SCSI cable from the SCSI backplane signal connector (J8) on the
system board and connect it to the RAID adapter. The following illustration shows

Chapter 2. Installing options 13

Note: See the documentation that comes with the RAID adapter for any

additional cabling instructions. That documentation also provides
information about installing the RAID software and configuring the RAID
adapter.

v If you plan to install an optional IBM Remote Supervisor Adapter, install it in

PCI-X slot 1. Use the ribbon cable that comes with the Remote Supervisor
Adapter to connect the 20-pin connector on the rear edge of the adapter to the
Remote Supervisor Adapter connector (J2) on the system board. For details
about installing a Remote Supervisor Adapter, see the documentation that comes
with the adapter. The following illustration shows the cable routing.

manufacturer. If you are installing a full-length adapter, you might have to
remove a plastic bracket secured to the adapter with 2 screws before
installing the adapter.

Attention: When you install an adapter, ensure that the adapter is
correctly seated in the connector before you turn on the server. Improperly
seated adapters might cause damage to the system board, the riser card
for slot 1, or the adapter.

b. Grasp the adapter by its top edge or upper corners, align it with the

connector, and press it firmly into the connector.

9. Slide the expansion-slot clip toward the server until it snaps into place to
secure the adapter in the adapter slot.

10. Connect any internal cables to the adapter. See the instructions that come with
the adapter for details.

Attention: Ensure that the cables do not block the flow of air from the fans.

11. If you removed the power-cord module to install the adapter in PCI-X slot 1,

install the module by reversing the procedure in step 7a on page 15. Ensure
that the alignment tab is fully seated in the slot on the side of the server.

12. If you installed the adapter in PCI-X slot 2, secure the adapter by flexing the
adapter-retention bracket toward the front of the server and inserting the front
corners of the adapter into the recesses in the latch.

13. Perform any configuration tasks required for the adapter.

Note: If you installed a Remote Supervisor Adapter:

a. Refer to the documentation provided with the Remote Supervisor

Adapter for information about installing the Remote Supervisor
Adapter firmware and configuring the adapter.

b. After you initially configure the adapter, you should create a backup

copy of it so that if you need to replace the adapter in the future,
you can restore the configuration and resume normal operation
more quickly.

14. If you have other options to install, install them now. Otherwise, go to
“Completing the installation” on page 27.

Working with a hard disk drive

This section describes how to install a hard disk drive in the server. Before you
install a hard disk drive, review the following information:

v The server supports two 25.4-mm (1-inch), slim, 3.5-inch hard disk drives. SCSI

models of the server come with a hot-swap SCSI backplane.

™

v The

v Non-hot-swap disk drives do not require a backplane or tray and they do not

16 IBM xSeries 335 Type 8676: Option Installation Guide

SCSI server models support low voltage differential (LVD) hot-swap drives.
Each hot-swap drive resides 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. Each hot-swap drive has a
single-connector-attached (SCA) connector, which plugs directly into the
hot-swap SCSI backplane. The backplane attaches to connector J18 on the
system board and controls the SCSI IDs for the hot-swap drives.

Note: The drive in bay 1 is assigned SCSI ID 0; the drive in bay 2 is assigned

SCSI ID 1.

have indicator LEDs. However, you must attach the blue rails that come with the
drive before installing it in the server.

v Non-hot-swap disk drives have a jumper block on the rear. Install a jumper in the

cable-selection position of the jumper block. For details, see the notes under step
4 on page 18, and the documentation that comes with the drive.

v If you install only one hard disk drive, for faster startup, install it in the primary

boot device bay. For hot-swap SCSI drives, the drive in bay 1 is the primary boot
device. For IDE drives, the drive in bay 2 is the primary boot device.

v If you are installing a hot-swap drive, continue with “Installing a hot-swap hard

disk drive”. If you are installing a non-hot-swap drive, go to “Installing a
non-hot-swap hard disk drive” on page 18.

Installing a hot-swap hard disk drive

Before you install a hot-swap hard disk drive, review the following information:

v Inspect the drive tray for any signs of damage.

v Ensure that the drive is installed in the tray correctly.

v If your server has an optional RAID adapter installed, see the documentation

provided with the adapter for information about installing a hard disk drive.

Complete the following steps to install a hot-swap SCSI hard disk drive:

Drive bay 2

Installing memory modules

This section describes how to install memory modules in the server. Before you
install memory modules, review the following information:

v The xSeries 335 Type 8676 server uses interleaved dual inline memory modules

(DIMMs), which requires that you add, remove, or replace DIMMs in pairs. Each
pair must be of the same type, capacity, and speed. Adding memory to the
server is an easy way to improve system performance. The server comes with
one pair of DIMMs installed in DIMM slots 1 and 2 on the system board.

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 in slots 3 and 4.
The server supports 256 MB, 512 MB, and 1 GB DIMMs. See the ServerProven
list at http://www.ibm.com/pc/compat/ on the World Wide Web for a list of
memory modules supported by the server. The following illustration shows the
memory slots on the system board.

Cabling the server

To share one monitor, keyboard, and pointing device (such as a mouse) among
multiple servers, connect the servers using Cable Chain Technology (C2T). In
addition, you can create an Advanced System Management (ASM) interconnect
network of connected servers by installing one or more Remote Supervisor
Adapters.

The following sections describe how to cable a C2T chain and an ASM interconnect
network.

Cabling a C2T chain

Use C2T interconnect cables to connect the servers into a chain. The following
illustration shows a C2T interconnect cable.

Configuration/Setup Utility program to update the server configuration. See
the following section and the User’s Guide for more information.

28 IBM xSeries 335 Type 8676: Option Installation Guide

Use a C2T breakout cable (available in the C2T cable option kit) to connect the first
server in the chain to the monitor, keyboard, and pointing device. The following
illustration shows a C2T breakout cable.

Note: You can connect a USB keyboard to the server using one of the USB ports.

After installing a USB keyboard, you might need to use the
Configuration/Setup Utility program to enable keyboardless operation and
prevent POST error message 301 from being displayed during startup. For
detailed information about this option and how to connect it to your server,
see the documentation that comes with the option.

Chapter 2. Installing options 29

Before cabling the C2T chain, review the following information:

v You can connect a maximum of 42 servers in a C2T chain.

v When connecting servers that are more than 3 U apart or on different racks, you

must use a 2-m (6.5-ft) C2T interconnect cable, which comes in the C2T cable
option kit. You can use only one 2-m (6.5-ft) cable in a chain.

v C2T interconnect cables are hot-swappable.

v Servers are numbered by their positions in the chain (1 through n). If one server

is removed from the chain, the remaining servers are renumbered. For example,
if the 12th server is removed from a chain of 15 servers, servers 13 through 15
are renumbered to 12 through 14.

v C2T numbering is independent of other server references. For example,

changing the position of a server in the C2T chain does not affect its IP address.

v C2T chaining supports a maximum video mode of 1024 x 768.

Complete the following steps to cable a C2T chain:

1. Turn off the servers.

2. Obtain a sufficient number of C2T interconnect cables. The server comes with
one C2T interconnect cable that can span approximately 3 U. A 2-m (6.5-ft) C2T
interconnect cable and a C2T breakout cable come in the C2T cable option kit.

The following illustration shows a C2T chain of four servers.

3. Connect a C2T interconnect cable from the C2T (IN) connector on the first
server in the chain (server 1 in the illustration, typically the bottom server in the
rack) to the C2T (OUT) connector on the second server in the chain (server 2 in
the illustration). The connectors on the ends of the cable are different and have
different colors (black for OUT and white for IN) to prevent you from connecting
them to the wrong connectors on the servers. Repeat this step until all the
servers in the chain are connected. You can connect up to 42 servers in this
manner.

30 IBM xSeries 335 Type 8676: Option Installation Guide

4. Connect a C2T breakout cable to the C2T (OUT) connector on the first server in
the chain (server 1 in the illustration).

5. Connect the monitor, keyboard, and pointing device to the connectors on the
C2T breakout cable. The keyboard and pointing-device connectors on the cable
have icons to help you identify them.

6. Turn on the servers and test the chain, using the procedure in the following
section.

When you add, remove, or replace servers or change cables in the chain, it is
possible for the select LED on more than one server to be lit. Press the select
button on any server in the chain to turn off the select LEDs on all but the selected
server.

If you are using a flat-panel monitor, you might need to adjust the image lock on the
monitor. Press the select button on one of the middle servers in the chain; then,
adjust the image lock on the monitor. For more information about adjusting the
image lock, see the documentation that comes with your monitor.

Testing the C2T chain

After cabling the C2T chain, test the monitor, keyboard, and pointing device to
ensure that they work with each server in the chain. Complete the following steps to
test the chain:

1. With the servers and the monitor turned on, press the select button on server 1
in the chain.

2. Verify that the monitor is working properly.

3. Use the pointing device (mouse) to start an application.

4. Test the keyboard by typing a few words within an application.

5. Repeat steps 1 through 4 for each server in the chain.

If any of the devices do not work with any of the servers, verify that all the cables
are correctly and fully connected; then, test the chain again. If the problem remains,
turn off all the servers and disconnect all the C2T interconnect cables; leave the
C2T breakout cable connected. Turn on server 1 and retry the devices. If the
devices work, one of the C2T interconnect cables is probably defective. Connect
server 2 to the chain and test the devices again. Continue adding servers to the
chain and testing them, one at a time, until you identify the defective cable.

Using the C2T chain

To select the server for which you want the monitor, keyboard, and pointing device
to work, press the select button on the server, or you can select the server by using
the keyboard:

1. Press Num Lock on the keyboard twice. The monitor screen goes blank.

2. Type the number of the server in the chain and press Enter. The monitor now
displays the image for the selected server, and the select LED on the selected
server is lit.

After you have used the keyboard to specify a server number, you can use the
same method (pressing Num Lock twice, then pressing + or -) to select other
servers in sequence.

Note: You cannot use the + and - keys to select a server if you made the previous

selection by pressing the select button on the selected server; you must
have made the previous selection through the keyboard.

Chapter 2. Installing options 31

If you turn off the selected server, the monitor screen goes blank, and you must
select another server. No more than two adjacent servers in the chain can be
disconnected from their power source for the chain to work properly.

Cabling an ASM interconnect network

An Advanced System Management (ASM) bus is integrated into the C2T
interconnect cables, so by adding one or more Remote Supervisor Adapters to a
C2T chain of servers, you can create an Advanced System Management (ASM)
interconnect network. For information about using a Remote Supervisor Adapter for
remote server management, see the documentation that comes with the adapter.

Before cabling the ASM interconnect network, review the following information:

v The cables in an ASM interconnect network are hot-swappable.

v Make sure that the firmware for the Remote Supervisor Adapter, ASM processor,

and integrated system management processor (ISMP) are at the latest level.

v The servers in an ASM interconnect network are referred to by their assigned

addresses, not by their positions in the rack.

An ASM interconnect network can have up to 24 RS-485 connections, depending
on the configuration. The connections can include Remote Supervisor Adapters,
ASM processors, ASM PCI adapters, and ISMPs. Use the following information to
determine the number of servers and connections that you can have on your ASM
interconnect network:

v Each Remote Supervisor Adapter, ASM processor, ASM PCI adapter, and ISMP

in a server that is connected to the network uses one connection. For example, if
a server that is connected to the network has a Remote Supervisor Adapter and
an integrated ASM processor, the server uses two connections on the network.

v The network must include at least one server with a Remote Supervisor Adapter

(either installed as an option or preinstalled in the server).

You can connect up to 23 xSeries 335 servers into an ASM interconnect network
using one Remote Supervisor Adapter. However, if you use both xSeries 335 and
xSeries 330 servers in the network, the xSeries 330 servers must be the
lowest-numbered servers in the chain. The following illustration shows an ASM
