This section provides information about locations and functions of the switch block on the system board assembly that contains the system I/O board and processor board.
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-assembly switch or jumper block that is not shown in the illustrations in this document are reserved.

|Switch number||Switch name||Default position||Description|
|SW5-1||Force BMC CPU reset||Off||Forces BMC and CPU into reset when changing it to the ON position.|
|SW5-2||Clear CMOS||Off||Clears the real-time clock (RTC) registry when changing it to the ON position.|
|SW5-3||Override power-on password||Off||Overrides the power-on password when changing it to the ON position..|
|SW5-4||FPGA reset||Off||Forces FPGA into reset when changing it to the ON position.|
|SW5-6||MFG mode||Off||Enables MFG mode of firmware (UEFI/XCC/FPGA) when changing it to the ON position.|
|SW5-7||At-Scale debug||Off||Enables BMC At-Scale debug when changing it to the ON position.|
|SW5-8||Low security||Off||Allows transitioning between signed official XCC builds and XCC test signed builds, and bypasses CRTM boot check of XCC firmware when changing it to the ON position.|
