Power Disconnect
The rear main power switch supplies AC
power to power module. The front
(standby) power switch causes the power
module to supply DC power to the
CompactPCI/PXI backplane whenever
the main power switch (rear panel) is in
the On (1) position. The rear-panel D-sub
connector facilitates remote inhibiting
operation. Both the rear main power
switch and the front (standby) switch
must be in the On position prior to use of
remote inhibit. The power cord provides
