Power problems
Power source problems
Action:
Press the Power On/Standby button to be sure it is on. If the server has a Power On/Standby button
1.
that returns to its original position after being pressed, be sure you press the switch firmly.
Plug another device into the grounded power outlet to be sure the outlet works. Also, be sure the
2.
power source meets applicable standards.
Replace the power cord with a known functional power cord to be sure it is not faulty.
3.
Replace the power strip with a known functional power strip to be sure it is not faulty.
4.
Have a qualified electrician check the line voltage to be sure it meets the required specifications.
5.
Be sure the proper circuit breaker is in the On position.
6.
If group power capping is supported on the server, be sure there is sufficient power allocation to
7.
support the server.
Be sure no loose connections exist

Power supply problems
Action:
Be sure no loose connections exist
1.
If the power supplies have LEDs, be sure they indicate that each power supply is working properly.
2.
If the LEDs indicate a problem with a power supply, replace the power supply. For more information,
see the server documentation on the HP website (http://www.hp.com/support).
Be sure the system has enough power, particularly if you recently added hardware, such as hard
3.
drives. Additional power supplies may be required. Check the system information from the IML.
For product-specific information, see the server documentation on the HP website
(http://www.hp.com/support).
For more information, see the HP Power Advisor on the HP website
(http://www.hp.com/go/hppoweradvisor).
If running a redundant configuration, be sure that all of the power supplies in the system are the
