Third Power Supply Fail
Header
Connect a cable from your power
supply to the JP8 header to pro-
vide warning of power supply fail-
ure. This warning signal is
passed through the PWR_LED pin
on JF2 to indicate a power failure
on the chassis. See the table on
the right for pin definitions. This
feature will not function on the
7043A-i, which has only a single
power supply module.
