System Recovery and Update Jumpers
One 8-pin header (J106), located near the NIC 1 connector, provides a total of five 2-pin jumper
blocks that are used to configure several system recovery and update options. The figure below
shows the jumper pins and their functions. The factory defaults are set to a protected mode for
each function. A jumper stored on pins 9-10 and needs to be moved to the location to perform
the particular function desired. For normal operation, the jumper should be on the storage pins.
An additional jumper is located at pins 7-8 to protect the Boot block of the BIOS code. This
jumper should be in place at all times and only removed when directed to by the release notes in
the BIOS update.
The following table describes each jumper option.

Table 61. Configuration Jumper Options
No connect. Default position for jumper storage.
Pins 7 and 8 should be jumpered to protect the BIOS bootblock from being
flashed.
If pins 5 and 6 are jumpered CMOS contents are set to factory defaults
during system reset.
If pins 3 and 4 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 the BIOS code has been corrupted.
If pins 1 and 2 are jumpered, administrator and user passwords areas in the
CMOS are cleared and set back to the factory default of null.
