SUPERSERVER 6028R-T/6028R-TT User's Manual

5-9 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 identi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.

LED indicator are provided on the

motherboard. The rear UID switch is

The rear UID LED (LE1) is located
