One of the power supplies in a node has failed or lost power.
Description
It is possible that a power cable was unplugged during recent maintenance or the circuit supplying power to the affected power
supply has failed.
Administrator action
Perform the following steps in the order listed. If the issue resolves after a step, there is no need to complete the subsequent
steps.
1. Confirm that both power cables are properly connected to the node.
2. View the LED lights on the power supplies and confirm the status of the power supply:
LED
Steady green
Blinking green
Steady amber
Blinking amber
No light
3. If only one node reports the issue, determine the cause of the problem by performing the following steps.
CAUTION: Do not move the power cable to another power supply in the same node as this will cause the node
to lose power.
● Locate the electrical outlet to which the problematic power supply is connected, and then determine if the outlet is
functioning properly by plugging the power cable into a different electrical outlet.
● If the issue is not resolved by using a different electrical outlet, move the power cable from the power supply that reports
the failure to the power supply of a node that does not report a failure. If the cable is the issue, replace the cable.
4. If the issue persists, take one power supply out of a different working node and attach the power supply to the affected
node.
CAUTION: Do not switch power supplies in the same node as this will cause the node to lose power.
● If the issue follows the power supply, the power supply must be replaced.
5. If multiple nodes report power supply issues, it is likely that the issue is environmental. Check each of the following items to
confirm the health of the power subsystem:
● Power Distribution Unit (PDU) functionality and status of any circuit breakers in the power path
● Power quality such as voltage, frequency values, and stability
● Uninterruptible Power Supply (UPS) health
6. If the issue is not constant and is limited to one node, move the power to another circuit. Next, one at a time, move both
power supplies.
If the above steps do not resolve the issue, gather logs, and then contact Technical Support for additional troubleshooting. For
