Steps to Follow
Troubleshooting steps:

Please validate that each troubleshooting step below is true for your environment. Each step will provide instructions or a link to the document for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.
Step 1 - Check incoming power. Confirm that the power cord(s) are connected securely at both ends and that the incoming power source is known to be operational and within the required specifications.  (ref. specific system using online SSH, click on Hardware Specifications under the Information Areas for exact power requirements) If uncertain check for tripped circuit breaker, blown fuse, etc. Reseat power cord(s) at both ends. Verify suspect power supply is seated properly. Depending on the system, power  supplies are usually accessed from the back; however on some systems the power supplies are located in the front, behind a bezel or door assembly that swings open.

     Gently push on the power supply to insure it is flush and properly seated in its location.

     Check the LED status on the front of the system. If the wrench light is on as a solid amber, this is telling us the system has a general hardware fault. At this point check the LED's on the power supply itself. A solid amber on the power supply is indicating failure and it will need to be replaced.

Step 2 - Once the power supply has been replaced and is continuing to show as either failed, faulted or LED's are still solid amber, verify the replacement power supply is not DOA (Dead On Arrival). If possible, swap the power supply with a known good power supply from another slot or spare system. If the suspect power supply fails in another slot, and PS in the swapped slot now shows as OK or LED is green, the replacement is DOA and will need to be replaced.

If a known good power supply is swapped into the slot of the original suspect power supply in question and fails then the issue is with the power distribution board and will need to be replaced.

Step 3 - At this point, if you have validated that each troubleshooting step above is true for your environment and the issue still exists, further troubleshooting is required. Gather explorer data collector from the system then contact Sun for support.
