Chapter 5: Advanced Serverboard Setup

5-17

5-10 Jumper Settings

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

connector. Pin 1 is identiﬁ ed 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.

CMOS Clear

JBT1 is used to clear CMOS (which will also clear any passwords). Instead of pins,

this jumper consists of contact pads to prevent accidentally clearing the contents

of CMOS.

To Clear CMOS

First power down the system and unplug the power cord(s).

With the power disconnected, short the CMOS pads with a metal object such

as a small screwdriver.

Remove the screwdriver (or shorting device).

Reconnect the power cord(s) and power on the system.

Note: Do not use the PW_ON connector to clear CMOS.
