System-Board Switches And Jumpers - IBM 7947E3U User Manual

System-board switches and jumpers

Some server models come with the Pass 8 level system board or the Pass 9 level
system board. The Pass 8 level system board does not have an identifying mark.
The Pass 9 level system board is identified by P9 on the corner of the system
board near the USB connectors on the rear of the server. If the system board is
updated in the future, it will also show the pass level on the system board.
The functionality of the two system boards are equivalent, except for the switch
blocks. The functions of the switch blocks on each of these system boards differs,
depending on the level of the system board that is installed in the server. The
following sections describe the switches and jumpers for each of these system
boards.

location and description of the switches and jumpers.
Note: If there is a clear protective sticker on the top of the switch block, you must
remove and discard it to access the switch.
The following table describes the jumpers on the Pass 8 level system board.
