DOM Power Connectors
Two power connectors for SATA DOM
(Disk_On_Module) devices are located
at JSD1/JSD2. Connect appropriate
cables here to provide power supply for
your Serial Link DOM devices.
TPM/Port 80 Header
A Trusted Platform Module (TPM)/Port
80 header is located at JTPM1 to provide
TPM support and a Port 80 connection.
Use this header to enhance system
performance and data security. See the
table on the right for pin definitions.

Jumper Settings
Explanation of Jumpers
To modify the operation of the motherboard,
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 identified with
a square solder pad on the printed circuit
board. See the diagram at right for an
example of jumping pins 1 and 2. Refer
to the motherboard layout page for jumper
locations.
Note: On two-pin jumpers, "Closed" means
the jumper is on and "Open" means the
jumper is off the pins.
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.
VGA Enable
Jumper JPG1 allows the user to enable
the onboard VGA connector. The default
setting is 1-2 to enable the connection.
See the table on the right for jumper
settings.
