Installing CPU Boards

If you ordered a CPU board factory-installed, you may skip this chapter. If you must install a CPU board in your system, read all of this information.

When actually performing the installation, refer to the following documents for information on installing CPU boards in the system:

∙Quick Hardware Installation that came with your system

∙Release Notes that came with your CPU board

∙Chapter 2 of this User Guide for the location of the CPU board slot on the system board (Figure 2-1)

Warnings When installing CPU boards, do not attempt to make any hardware changes unless you are a qualified technician. Ask your dealer for assistance.

There are two released versions of system BIOS. One is for uniprocessor CPU boards, and the other is for dual processor CPU boards. These versions of BIOS are not interchangeable. Flashing the incorrect version renders the system unusable.

For example, if you flash the BIOS version released for a uniprocessor CPU board on a system configured with a dual CPU board you cannot use the system. If this happens, you must insert the appropriate CPU board into the system and reflash the original BIOS.
