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 packages until
you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
vLimit your movement. Movement can cause static electricity to build up around
you.
vHandle the device carefully, holding it by its edges or its frame.
vDo not touch solder joints, pins, or exposed printed circuitry.
vDo not leave the device where others can handle and possibly damage the
device.
vWhile the device is still in its static-protective 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.)
vRemove the device from its package and install it directly into your server without
setting it down. If it is necessary to set the device down, place it in its
static-protective package. Do not place the device on your server cover or on a
metal table.
vTake additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.

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:
vAvoid 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.
vDo not allow your necktie or scarf to hang inside the server.
vRemove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
vRemove items from your shirt pocket (such as pens or pencils) that could fall into
the server as you lean over it.
vAvoid dropping any metallic objects, such as paper clips, hair pins, or screws,
into the server.
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 following:
vSlot 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.
vSlots 2 through 7 support hot-plug, 64-bit, 100 MHz, PCI or PCI-X, 3.3 V
adapters.
vIf 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
vLocate the documentation that comes with the adapter and follow those
instructions 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.
© Copyright IBM Corp. 2003 5

This section contains the procedure for installing a hot-plug or non-hot-plug PCI or
PCI-X adapter. If your operating system supports hot-plug PCI or PCI-X adapters,
you can replace a failing hot-plug PCI or PCI-X adapter with a new hot-plug PCI or
PCI-X adapter of the same type without turning off power to the server. If your
operating system and adapter also support the hot-add feature in slots 4 through 7,
you can install a new adapter without turning off the power to the server.
Note: You do not have to turn off the server to install hot-plug adapters in the
hot-plug slots. However, you must turn off the server when performing any
steps that involve installing or removing cables.
Important: Do not remove a hot-plug PCI or PCI-X adapter before performing the
operating-system-defined procedure for disabling the Active
™
PCI-X (hot-plug) slot
that contains the adapter. Failure to do so might cause your system to lock up. See
your operating-system documentation.
For more detailed instructions, information, and additional system-board illustrations,
see the Option Installation Guide on the xSeries Documentation CD.
The following illustration shows the location of the adapter slots for the xSeries 255
Type 8685 server.
Note: A cable is attached to the hot-plug PCI-X switch card at system-board
connector J20 so that the hot-plug function will work properly for PCI-X slots
2 through 7. Do not disconnect this cable.

2. If you are installing a non-hot-plug adapter, turn off the server and disconnect
all power cords and external cables.
3. Remove the top cover.
4. Select the slot in which you want to install the adapter.
Note: PCI-X slots 2 through 7 support hot-plug PCI and PCI-X adapters. If
you are using the hot-add feature, be sure to install the adapters in
PCI-X slots 4 through 7 to maintain an optimum speed for the Ethernet
controller on PCI bus B (PCI-X slots 2 and 3).
5. If you are installing a hot-plug adapter or using the hot-add feature, disable the
selected PCI-X slot from your operating system. (See the documentation that
comes with your operating system for information about disabling a hot-plug
PCI-X slot.) Disabling the PCI-X slot turns off the power-on LED for that PCI-X
slot.
Attention: Make sure that the power-on LED for the hot-plug PCI slot is off
before you continue with the next step.
