This chapter describes the server components, the server
controls and light-emitting diodes (LEDs), and how to turn the system-board
tray on and off.
In addition to the instructions in this chapter for installing
optional hardware devices, updating the firmware and device drivers,
and completing the installation, Lenovo Business Partners must also
complete the steps in Instructions for Lenovo Business Partners.
Important: To help ensure that
the devices that you install work correctly and do not introduce problems,
observe the following precautions.
- Make sure that the server and the installed firmware levels
support the devices that you are installing. If necessary, update
the UEFI and IMM2.1 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.
For a list of supported optional devices for the server, see the IBM ServerProven website.
- Use the best practices to apply current firmware and device-driver
updates for the server and optional devices. To download the Firmware
Update Guides document, go to . Additional hints and tips are available from
the following website:
- 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 DSA Preboot diagnostic programs for information
about how to run diagnostics.
- Follow the installation procedures in this chapter and
use the correct tools. Incorrectly installed devices can cause system
failure because of damaged pins in sockets or connectors, loose cabling,
or loose components.
