Chapter 5. Removing And Replacing Components; Installing Optional Devices - Lenovo x3550 M5 Installation And Service Manual

Chapter 5. Removing and replacing components

There are three types of replaceable components.
• Structural parts: Purchase and replacement of structural parts (components, such as chassis assembly,
top cover, and bezel) is your responsibility. If Lenovo acquires or installs a structural component at
your request, you will be charged for the service.
• Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If Lenovo
installs a Tier 1 CRU at your request, you will be charged for the installation.
• Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or request Lenovo to install it, at
no additional charge, under the type of warranty service that is designated for your server.
See Chapter 4 "Parts listing, Lenovo System x3550 M5 Type 5463" on page 97 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 1023.

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, Business Partners must also complete the steps in
"Instructions for Business Partners" on page 118.
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
33. For a list of supported optional devices for the server, see http://www.lenovo.com/ serverproven/.
2. Use the best practices to apply current firmware and device-driver updates for the server and
optional devices. To download the "System x Firmware Update Best Practices" document, go
to www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5082923&brandind=5000008.

3. 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 "Running the DSA Preboot
diagnostic programs" on page 68 for information about how to run diagnostics.
