SUPERSERVER 8047R-TRF+/7RFT+ USER'S MANUAL

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

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

1. First power down the system and unplug the power cord(s). It is also

recommended that you remove the onboard battery from the serverboard.

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

as a small screwdriver.

3. Remove the screwdriver (or shorting device).

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

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

GLAN1/2 Enable/Disable

Change the setting of jumper JPTG1

to enable or disable the LAN1/LAN2

Ethernets port on the serverboard. The

default setting is enabled. See the table

on the right for jumper settings.
