Chapter 5. Removing and replacing server components
Replaceable components are of four types:
v Consumable parts: Purchase and replacement of consumable parts
(components, such as batteries and printer cartridges, that have depletable life)
is your responsibility. If IBM acquires or installs a consumable part at your
request, you will be charged for the service.
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 4, “Parts listing, System x3400 M3 Types 7378 and 7379,” on page
141 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 Information document.
Installation guidelines
Before you install optional devices, read the following information:
v
Read the safety information that begins on page vii and the guidelines in
“Handling static-sensitive devices” on page 151. 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
If you must start the server while the cover is removed, make sure that no one is
near the server and that no tools or other objects have been left inside the
server.
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 Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and other devices.
v
Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v
You do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.
v
Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the server, open or close a latch, and so on.
