Processor Installation Locations
Processors are housed on the processor extender board located under the top cover in the top service bay. The
processor extender board can hold one, two, three, or four processors. If fewer than four processors are
installed to be installed, the lower logical address locations must be used. (Example: if only two processors are
to be installed, they must be installed as CPU0 and CPU1.) Processor installation locations are listed in
Table 2-2.
CAUTION Do not modify the settings of the DIP switches located on the processor extender board. These
switches are for factory use. Failure to observe this caution will result in system failure.
Removing the Processor Extender Board
To remove the processor extender board, perform the following steps:
1. Press the latch on the extraction levers located on each side of the processor extender board. (See
Figure 2-6.)
