The following illustrations show the location of the switches on the server.
If there is a clear protective sticker on the top of the switch blocks, you must remove and discard it to access the switches.
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.Figure 1. System-board-assembly switch
SW5 switch block
The following table describes the functions of the SW5 switch block on the system board (system board assembly).
|Switch-bit number||Switch name||Default position||Description|
|1 SW5–1||Force BMC CPU reset||Off||Forces BMC and CPU into reset when changing it to the ON position.|
|2 SW5–2||Clear CMOS||Off||Clears the real-time clock (RTC) registry when changing it to the ON position.|
|3 SW5–3||Password override||Off||Overrides the power-on password when changing it to the ON position.|
|4 SW5–4||FPGA reset||Off||Forces FPGA into reset when changing it to the ON position.|
|6 SW5–6||MFG mode||Off||Enables MFG mode of firmware (UEFI/XCC/FPGA) when changing it to the ON position.|
|7 SW5–7||At-Scale debug||Off||Enables BMC At-Scale debug when changing it to the ON position.|
|8 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.|
