Chapter 2. Installing options

This chapter provides the basic information needed to install options in your server.
This section is for all users but is written with the experienced user in mind. If you need
more detailed installation information, see the Option Installation Guide on the xSeries
Documentation CD.

Working inside a server with the power on

Your server supports hot-plug, hot-add, and 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:

Installing adapters

This section describes how to install hot-plug and non-hot-plug peripheral component
interconnect (PCI) and PCI-X adapters. Before you install adapters, review the follow-

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.
Do not allow your necktie or scarf to hang inside the server.
Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
Remove items from your shirt pocket (such as pens or pencils) that could fall into
the server as you lean over it.
Avoid dropping any metallic objects, such as paper clips, hair pins, or screws, into
the server.
Slot 1 supports a non-hot-plug, 32-bit, 33 MHz, optional PCI adapter, such as the
IBM Remote Supervisor Adapter. If you install the optional Remote Supervisor
Adapter in this server, you must install the adapter in PCI slot 1. However, you can
install other compatible adapters in this slot.
If you install the optional IBM Remote Supervisor Adapter in the server, use the
ribbon cable that comes with the adapter to connect the adapter to the system-
management connector (J16) on the system board. The external power adapter
that comes with the IBM Remote Supervisor Adapter is not required with this
server.
Slots 2 through 7 support hot-plug, 64-bit, 100 MHz, PCI or PCI-X, 3.3V adapters.
If you install an adapter with a speed of less than 100 MHz, the speed of that PCI
bus will be reduced to the speed of the slowest device on that bus.
To maintain an optimum speed for the Ethernet controller on PCI bus B (PCI-X
slots 2 and 3), install the following types of adapters in PCI-X slots 4 through 7:
— Redundant array of independent disks (RAID) adapters
— 33 MHz or 66 MHz speed adapters
— PCI adapters
Locate the documentation that comes with the adapter and follow those instruc-
tions in addition to the instructions in this chapter. If you need to change the switch
or jumper settings on your adapter, follow the instructions that come with the
adapter.
