Important:
1. Before you change any switch settings or move any jumpers, turn off the server;
then, disconnect all power cords and external cables. (Review the information in
“Safety” on page vii, “Installation guidelines” on page 36, “Handling
static-sensitive devices” on page 38, and “Turning off the server” on page 21.)

in this document are reserved.
Pass 9 level system board
If the server has the Pass 9 level system board, the following illustration shows the
location and description of the switches and jumpers. The Pass 9 level system
board has a P9 (with a part number to the right of it) on the corner of the system
board near the USB connectors on the rear of the server.
Note: If there is a clear protective sticker on the top of the switch blocks, you must
remove and discard it to access the switches.
The default positions for the UEFI and the IMM recovery jumpers are pins 1 and 2.
