Chapter 4. Removing and replacing 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,” on page 59 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 remove or replace a component, read the following information:
v
Read the safety information that begins on page vii and the guidelines in
“Handling static-sensitive devices” on page 72. 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
Do not attempt to lift an object that you think is too heavy for you. If you have to
lift a heavy object, observe the following precautions:
– Make sure that you can stand safely without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy
object.
– To avoid straining the muscles in your back, lift by standing or by pushing up
with your leg muscles.
v
Back up all important data before you make changes to disk drives.
v
Have a small Phillips screwdriver available.
v
You do not have to turn off the system-board tray to install or replace hot-swap
drives or hot-plug Universal Serial Bus (USB) devices. However, you must shut
down the operating system of the system-board tray before you remove the
system-board tray from a chassis.
v
Blue on a component indicates touch points, where you can grip the component
to remove it or install it, 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 system-board
tray and operating system support hot-swap capability, you can remove or install
the component while the system-board tray 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.
