Power Supply Failure/Power Fault Detect (JPWF)
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 (the default setting) with JPWF to prevent false alarms. The table below describes
the jumper settings.

Front Panel Audio Control Jumper (Front panel audio) (J8)
When front panel headphones are plugged in, the back panel audio output is disabled.
This is done through the FP Audio header (J8). If the front panel interface card is not
connected to the front panel audio header, jumpers should be installed on the header
(J8) pin pairs: 1-2, 5-6, and 9-10. If these jumpers are not installed, the back panel line
out connector will be disabled and microphone input Pin 1 will be left floating, which
can lead to excessive back panel microphone noise and cross talk. The table below
describes the jumper settings.
