Resolving power-on issues

Follow these procedures if you have problems powering on or off your server or expansion enclosures.

Problem

Follow these procedures if you unsuccessfully attempt to power on or off the server or expansion enclosure.

Investigation

If the enclosure is currently powered off and will not power on:
  • Check to ensure that the storage unit is receiving power from the outlet.
    Note: You can use the ac LED indicator on the power supply to determine if the power supply is receiving power from the outlet.
  • Check the cord to the power supply.

    Ensure that the cords are securely inserted into both the source outlet and the power supply.

  • Ensure that the cords are not faulty.

    Replace the power cord with a cord that you know is in working condition.

  • If the problem is with an expansion enclosure, push the power button on the rear operator panel of the expansion enclosure.
If the enclosure is currently powered on and will not power off:

Ensure that all resources contained within the enclosure are offline. Use the Status page of the DS Storage Manager to verify that all resources that are contained within the enclosure are offline. Take online resources offline before reattempting to power off the enclosure.

If, after you complete all of the steps above, you still receive an error message, call IBM Support.
IBM Support personnel must determine the cause of the problem and find the appropriate resolution.
