This section contains information on the location of the switches, jumpers, and buttons on the server.
Before you change any switch settings or move any jumpers, turn off the server; then, disconnect all power cords and external cables. Review the following information:
Any system-board switch or jumper block that is not shown in the illustrations in this document are reserved.
If there is a clear protective sticker on the top of the switch blocks, you must remove and discard it to access the switches.
