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.
VGA Enable/Disable
JPG1 allows you to enable or disable
the VGA port. The default position is on
pins 1 and 2 to enable VGA. See the
table on the right for jumper settings.
GLAN1/2 Enable/Disable
Change the setting of jumper JPL1 to
enable or disable the GLAN1/GLAN2
Ethernets port on the serverboard. See
the table on the right for jumper set-
tings. The default setting is enabled.
3rd Power supply Fail Detect
The system can notify you in the event
of a power supply failure. This feature
is available when three power supply
units are installed in the chassis with
one acting as a backup. If you only have
one or two power supply units installed,
you should disable this detection feature
(the default setting) with JP13 to prevent
false alarms.
