devices, or adhesive tape from the source DC circuit breakers, and energize the source DC circuits to the
power supplies.
Turn the power switch to the On (|) position on the power supply. Turning on the power switch also
engages a pawl that locks the power supply in the chassis.

INPUT OK 1 LED—If you have source DC cables attached to the VE-1 pair of power supply inputs,
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing.
INPUT OK 2 LED—If you have source DC cables attached to the VE-2 pair of power supply inputs,
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing.
INPUT OK 3 LED—If you have source DC cables attached to the VE-3 pair of power supply inputs,
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing.
FAN OK LED is green.
OUTPUT FAIL LED is not lit.
