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.
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.
LAN1/2 Enable/Disable
Change the setting of jumper JPL1 to
enable or disable the LAN1 and LAN2
Ethernets ports. 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. Jumping
pins 1-2 will cause WD to reset the
system if an application hangs. Jumping
pins 2-3 will 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.
Note: When enabled, the user needs to
write their own application software in
order to disable the Watch Dog Timer.
Manufacture Mode
JPME1 allows the user to flash the sys-
tem firmware from a host server. Jump
pins 2-3 to bypass SPI flash security,
and force ME into Recovery mode in
order to use recovery jumpers. See the
table on the right for jumper settings.
VGA Enable
Jumper JPG1 allows the user to enable
the onboard VGA connector. The default
setting is on pins 1-2 to enable the con-
nection. See the table on the right for
jumper settings.
PCI-E Switch Enable
Close pins 1-2 of JPX1 to enable the
onboard PCI-E switch on the mother-
board. See the table on the right for
jumper settings.
