Power source issues

Cause

• The server is not powered on.
• Components or cables might not be properly connected or seated.
• The grounded power outlet is not working.
• The power cord is not functional.
• The power strip is not functional.
• The circuit breaker is in the off position.
• The line voltage is insufficient for the load.
• Sufficient power is not allocated to support the server.

Action

1. Press the Power On/Standby button to be sure it is on. If the server has a Power On/Standby button that returns to its original position after being pressed, be sure you press the switch firmly. For more information about system power LED status, see "System Power LED definitions."
2. Be sure no loose connections exist. For more information, see "Resolving loose connections."
3. Plug another device into the grounded power outlet to be sure the outlet works. Also, be sure the power source meets applicable standards.
4. Replace the power cord with a known functional power cord to be sure it is not faulty.
5. Replace the power strip with a known functional power strip to be sure it is not faulty.
6. Be sure the proper circuit breaker is in the On position.
7. Have a qualified electrician check the line voltage to be sure it meets the required specifications.
8. If Enclosure Dynamic Power Capping or Enclosure Power Limit is enabled on supported servers, be sure there is sufficient power allocation to support the server. For more information, see the following documents:
