Chapter 2. Installing and replacing a high speed switch module 9
• Configuration requirements for the switch module and the BladeCenter unit might vary. You
can obtain up-to-date information about the switch module and the BladeCenter unit at
http://www.ibm.com/systems/bladecenter/.
Installation guidelines
Before you install the switch module in the BladeCenter unit, read the following information:
• Read the safety information that begins on page v, “Handling static-sensitive devices” on
page 10, and the safety statements in the BladeCenter unit documentation. This information
will help you work safely.
• Observe good housekeeping in the area where you are working. Place removed covers and
other parts in a safe place.
• Blue on a component indicates touch points, where you can grip the component to remove it
from or install it in the blade server or BladeCenter unit, open or close a latch, and so on.
• Orange on a component or an orange label on or near a component on the switch module,
blade server, or BladeCenter unit indicates that the component can be hot-swapped, which
means that if the BladeCenter unit and operating system support hot-swap capability, you can
remove or install the component while the BladeCenter unit 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.
• You do not have to turn off the BladeCenter unit to install or replace any of the hot-swap
modules on the front or rear of the BladeCenter unit.
• When you install a switch module in the BladeCenter unit, you must also install a compatible
I/O expansion card in the blade server to support the switch module.
• When you are finished working on the blade server or BladeCenter unit, reinstall all safety
shields, guards, labels, and ground wires.
• For a list of supported optional devices for the BladeCenter unit and other IBM products, see
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
System reliability guidelines
To help ensure proper cooling, performance, and system reliability, make sure that the following
requirements are met:
• Each of the module bays on the rear of the BladeCenter unit contains either a module or a filler
module.
• A removed hot-swap module is replaced with an identical module or filler module within 1
minute of removal.
• A removed hot-swap blade server is replaced with another blade server or filler blade within 1
minute of removal.
• The ventilation areas on the sides of the blade server power modules and blowers are not
blocked.
• You have followed the reliability guidelines in the documentation that comes with the
BladeCenter unit.
