Troubleshooting the Supervisor Modules
Warning
Hazardous voltage or energy may be present on DC power terminals. Always replace cover when
terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in
place.
Statement 1075
d. Turn on the newly connected DC power source at the circuit breaker.
e. Turn the power switch on the power supply unit to ON (or 1).
f. Check the Input LEDs to see if they are on yet.
g. If the Input LEDs are not on, call TAC.
Step 5 If the Output LED is not lit, verify that the power switch on the power supply unit is turned to ON (or
1). If not, turn it to ON (or 1) and see if the LED turns on.
Step 6 If the Output LED is not lit, verify that the power supply unit is properly seated in the power supply bay
by performing the following steps:
a. Turn the power switch on the power supply unit to standby (STBY or 0).
b. Turn off the DC circuit by manually shutting it down at the circuit breaker.
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
c. Pull the power supply unit part way out of the chassis and then push it back into the power supply
bay. To remove a 6-kW power supply, you must first fully loosen its four captive screws. To remove
a 3-kW power supply, you must press and hold its release latch to the left. When you reinstall a 6-kW
power supply, tighten its four captive screws to 8 in-lb (0.90 N·m).
d. Turn on the DC power source at the circuit breaker.
e. Turn the power switch to ON (or 1).
f. Verify that the Output LED turns on.
Step 7 If the Output LED is still not on, verify that the power supply unit is functional by replacing it with
another power supply (see the “Replacing a DC Power Supply Unit During Operations” section on
page 10-9) and plugging its power cords into the same DC source. If the Input and Output LEDs turn
green on the replacement power supply unit, contact TAC (see the “Contacting Customer Service”
section on page 9-8) to replace the defective power supply unit.
If you cannot determine the problem with the power supply or determine which power supply unit has
the problem, contact TAC.
Troubleshooting the Supervisor Modules
The following conditions indicate a problem with one or more supervisor modules:
• The SUP LED on the chassis is amber.
• The STATUS LED on a supervisor module is amber, red, or not lit.
• The CMP STATUS LED on a supervisor 1 module is amber or red.
• An ACT LED on a supervisor module is not lit.
