3rd Power Supply Fail Signal
Enable/Disable
The system can notify you in the event
of a power supply failure. This feature
assumes that three redundant power
supply units are installed in the chas-
sis. If you only have one or two power
supplies installed, you should disable
the function with the J3P header to pre-
vent false alarms. See the table on the
right for jumper settings.

The JI C1/2 pair of jumpers allows you
to connect the System Management
Bus to any one of the PCI expansion
slots. The default setting is closed (on)
for both jumpers to enable the connec-
tion. Both connectors must be set the
same (JI 2 C1 is for data and JI
the clock). See the table on right for
jumper settings

Compact Flash Master/Slave

The JCF1 jumper allows you to assign
either master or slave status to an
installed compact fl ash card. See the
table on the right for jumper settings.

VGA Enable/Disable

the VGA port. The default position is
on pins 1 and 2 to enable VGA. See

tings.
