Chapter 5. Removing and replacing components
There are three types of replaceable components.
v Structural parts: Purchase and replacement of structural parts (components, such
as chassis assembly, top cover, and bezel) is your responsibility. If IBM acquires
or installs a structural component 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.
See Chapter 4, “Parts listing, IBM System x3550 M5 Type 5463,” on page 111 to
determine whether a component is a structural part, Tier 1 CRU, or Tier 2 CRU.
For information about the terms of the warranty, see the Warranty Information
document that comes with the server.
For more information about getting service and assistance, see Appendix D,
“Getting help and technical assistance,” on page 821.
Installing optional devices
This section provides detailed instructions for installing optional hardware devices
in the server.
In addition to the instructions in this chapter for installing optional hardware
devices, updating the firmware and device drivers, and completing the installation,
IBM Business Partners must also complete the steps in “Instructions for IBM
Business Partners” on page 125.
Important: To help ensure that the devices that you install work correctly and do
not introduce problems, observe the following precautions:
1. Make sure that the server and the installed firmware levels support the devices
that you are installing. If necessary, update the UEFI and IMM firmware and
any other firmware that is stored on the system board. For information about
where firmware is stored in the server, see “Updating the firmware” on page
35. For a list of supported optional devices for the server, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us.
2. Use the best practices to apply current firmware and device-driver updates for
the server and optional devices. To download the “IBM System x Firmware
Update Best Practices” document, go to www.ibm.com/support/entry/portal/
docdisplay?lndocid=MIGR-5082923&brandind=5000008. Additional hints and
tips are available from the following sites:

working correctly. Start the server and make sure that the operating system
