Chapter 4. Removing and replacing blade server components
Replaceable components are of three types:
v Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your
responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for
the installation.
v
Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or
request IBM to install it, at no additional charge, under the type of warranty
service that is designated for your server.
v Field replaceable unit (FRU): FRUs must be installed only by trained service
technicians.
See Chapter 3, “Parts listing, Type 8850,” on page 53 to determine whether a
component is a Tier 1 CRU, Tier 2 CRU, or FRU.
For information about the terms of the warranty and getting service and assistance,
see the Warranty and Support Information document.
Installation guidelines
Before you install options, read the following information:
v
Read the safety information that begins on page v and the guidelines in
“Handling static-sensitive devices” on page 58. This information will help you
work safely.
v
Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
v Back up all important data before you make changes to disk drives.
v
Before you remove a hot-swap blade server from the BladeCenter
®
unit, you
must shut down the operating system and turn off the blade server. You do not
have to shut down the BladeCenter unit itself.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the blade 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
