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, Type 7942 server,” on page 37 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.

Before you install optional hardware, make sure that the server is working
correctly. Start the server, and make sure that the operating system starts. If the
server is not working correctly, see Chapter 5, “Diagnostics,” on page 83 for
diagnostic information.
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.
