SW4-4 (BMC Flash Write Protect)
This switch allows write protection of the BMC flash. Factory default is open.

SW5-1, SW5-2, SW6-2 (Battery Back/Clear CMOS)
These switches are used to control the battery backup for CMOS memory and for clearing CMOS
memory. When closed, SW5-1 connects the CMOS memory to the on-board battery. To clear
CMOS, open SW5-1 and close SW5-2 and SW6-2. After two seconds, return SW5-2 and SW6-2 to
the open position and SW5-1 to the closed position. Factory default is SW5-1 closed, SW5-2 open,
and SW6-2 open.
closed and SW5-2 should be open during normal operation.
SW5-3 (Video Select)
This switch allows video signals to be active at both the faceplate and the rear panel I/O connector
or only at the rear panel I/O connector. Open SW5-3 to activate video signals at faceplate connector
J10 and at rear panel I/O connector J5. The BIOS setup then controls which connector receives
video signals. Close SW5-3 to route video signals to rear panel I/O connector J5 only. If SW5-3 is
closed, the BIOS can be set to route video signals to the front, but SW5-3 overrides the BIOS
setting and sends video out the rear. Factory default is open.
SW5-4, SW6-1 (Reserved)
The functions of these switches are reserved and should not be altered from their factory default
settings (open).
