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.

Unit Identier Switch/UID LED
Indicator
A Unit Identier (UID) switch and an
LED indicator are provided on the
motherboard. The rear UID switch is
located next to the VGA port on the
backplane. The front UID switech is
located on pin 13 of the JF1 header.
The rear UID LED (LE1) is located
next to the UID switch and the front
UID LED is located on pin 7 on JF1.
When you press the UID switch, the
UID LED will be turned on. Press the
UID switch again to turn off the LED
indicator. The UID indicator provides
easy identication of a system unit that
may be in need of service.
Note: UID can also be triggered via
IPMI on the motherboard. For more
information on IPMI, please refer to
the IPMI User's Guide posted on our
website.

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).
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.
LAN1/LAN2 Enable/Disable
Use JPL1 to enable/disable the LAN
ports 1/2. See the table on the right
for jumper settings. The default setting
is Enabled.

Watch Dog Enable/Disable
Jumper JWD controls the Watch Dog
function. Watch Dog is a system moni-
tor that can reboot the system when a
software application hangs. Close pins
1-2 to to reset the system if an applica-
tion hangs. Close pins 2-3 to generate
a non-maskable interrupt signal for the
application that hangs. See the table
on the right for jumper settings. Watch
Dog must also be enabled in BIOS.
