System Recovery and Update Jumpers
The server board SE7500WV2 provides one 11-pin single online header (J1D4), which provides a total
of three 3-pin jumper blocks that are used to configure several system recovery and update options.
The following table describe each jumper option. Please note that pins 4 and 8 are removed.
Label
Jumper Name
Description
A
RJ-45 Serial port Config
Configurations either a DSR or a DCD signal to
the connector.
B
CMOS CLR
If these pins are jumpered, the CMOS settings are
cleared. These pins should not be jumpered for
normal operation.
C
PSWD CLR
If these pins are jumpered, the password is cleared.
These pins should not be jumpered for normal
operation.
Option
Description
CMOS Clear
If pins 1 and 2 are jumpered ( default ), preservation of configuration CMOS
through system reset is controlled by the BMC. If pins 2 and 3 are jumpered,
CMOS contents are set to manufacturing default during system reset.
Password Clear If pins 5 and 6 are jumpered ( default ), the current system password is
maintained during system reset. If pins 6 and 7 are jumpered, the password
is cleared on reset.
Recovery Boot
If pins 9 and 10 are jumpered ( default ) the system will attempt to boot using
the BIOS programmed in the Flash memory. If pins 10 and 11 are jumpered,
the BIOS will attempt a recovery boot, loading BIOS code from a floppy
disk into the Flash device. This is typically used when BIOS code has been
corrupted.
