Chapter 4. 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 3, “Parts listing, System x3755 Type 8877 and 7163,” on page 25 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, “Working inside the server
with the power on” on page 39, and the guidelines in “Handling static-sensitive
devices” on page 39. This information will help you work safely.
v Before you install optional hardware devices, make sure that the server is
working correctly. Start the server, and make sure that the operating system
starts, if an operating system is installed, or that a 19990305 error code is
displayed, indicating that an operating system was not found but the server is
otherwise working correctly. If the server is not working correctly, see Chapter 5,
“Diagnostics,” on page 73 for diagnostic information.
v
When you install your new server, take the opportunity to download and apply
the most recent firmware updates. This step will help to ensure that any known
issues are addressed and that your server is ready to function at maximum levels
of performance. To download firmware updates for your server, go to
http://www.ibm.com/servers/eserver/support/xseries/index.html, select
System
x3755 from the Hardware list, and click the Download tab. For additional
information about tools for updating, managing, and deploying firmware, see the
System x and xSeries Tools Center at http://publib.boulder.ibm.com/infocenter/
toolsctr/v1r0/index.jsp.
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 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 stand safely without slipping.
– Distribute the weight of the object equally between your feet.
