Chapter 5: Advanced Serverboard Setup

5-10 Jumper Settings
Explanation of Jumpers
To modify the operation of the
serverboard, jumpers can be used
to choose between optional settings.
Jumpers create shorts between two
pins to change the function of the con-
nector. Pin 1 is identified with a square
solder pad on the printed circuit board.
See the serverboard layout pages for
jumper locations.
Note: On a two-pin jumper, "Closed"
means the jumper is on both pins and
"Open" means the jumper is either on
only one pin or completely removed.

JBT1 is used to clear the saved system setup stored in the CMOS chip. To clear
the contents of the CMOS, completely shut down the system, remove the AC power
cord and then short JBT1 with a jumper. Remove the jumper before powering on
the system again. This will erase all user settings and revert everything to their
factory-set defaults.
