AT-SBxPWRSYS1 DC Power Supply
If you suspect a problem with the DC power supply, examine its LEDs. The power supply is operating normally when the DC IN and DC OUT LEDs are solid green and the Fault LED is off. Possible fault conditions and their solutions are described here:
Fault Condition 1: If the DC IN LED is off, the power supply is not receiving power, has overheated and been disabled, or has failed and needs to be replaced. Try the following:
Verify that the On/Off switch on the power supply is in the On position.
Verify that the DC circuit breaker is on.
Verify that the positive and negative power wires are correctly and securely connected to the terminal block on the power supply and circuit breaker.
Verify that the DC circuit break has power by attaching another device to it.
Verify that the power from the DC circuit break is within the required levels of the power supply. Refer to “Power Specifications” on page 236.
If the chassis is still operating, use the SHOW PSU or SHOW PSU ALL command from a local or remote management session to determine if the power supply has overheated and shutdown.
Fault Condition 2: If the DC IN LED is solid green but the DC OUT LED is off, the power unit is generating insufficient DC power. Replace the power supply.
Fault Condition 3: If the Fault LED is solid amber, try the solutions in Fault
Condition 1. If they do not resolve the problem, replace the power supply.
Note
The power supply is hot swappable. If the chassis has two power supplies and one of them fails, you do not have to power off the operational power supply to replace the failed unit.
Fault Condition 4: If the LEDs on the power supply indicate normal operations but the PSU LED on the active master control card is off or is showing a fault condition, try the following suggestions:
The control card may not be able to detect the DC power supply because it is not running the most recent version of the management software. For instructions on how to verify the
