SW3-1 (BIOS Recovery Module/Flash Select)
If your system is having trouble booting then you can try using this switch to boot from the backup
BIOS. When SW3-1 is open, the BIOS boots from the normal location of on-board flash memory.
When SW3-1 is closed, the BIOS boots from the backup BIOS. See
Configuration Overview” on page 48
SW3-1 Status
SW3-2 (Bypass BMC to power up)
If you are having difficulty powering up the ZT 5515 then closing this switch will bypass the BMC
firmware and (possibly) allow the board to boot. This can be used if the BMC firmware on the
board is not available. This switch should be closed when the board is used in a non-PICMG* 2.9
chassis (i.e., a chassis that does not supply IPMB power) or when power up difficulties are
encountered.
SW3-2 Status
SW3-3 (Ethernet SMBUS isolation)
Closing this switch will disable the SMBUS connection from BMC to the Ethernet. This is used
when user want to disable remote management.
SW3-4 (VGA Routing Control)
This switch controls the routing of VGA signals to either the front or rear of the board. The default
switch configuration routes VGA signals to the faceplate video connector.
