Power problems

Use this information to diagnose and resolve power issues with the blade server.

To check for power problems, make sure that:
  • The LEDs on all the BladeCenter power modules are lit.
  • Power is being supplied to the BladeCenter unit.
  • The BladeCenter unit support installation of the blade server type.
  • The BladeCenter unit has the correct power configuration to operate the blade server bay where the blade server is installed (see the documentation for your BladeCenter unit).
  • The BladeCenter unit power-management configuration and status support blade server operation (see the Advanced Management Module User's Guide or the Management Module Command-Line Interface Reference Guide for information).
  • Local power control for the blade server is correctly set (see the Management Module User's Guide or the Advanced Management Module Command-Line Interface Reference Guide for information).
  • The power-on LED on the blade server flashes slowly before you press the power-control button.
    Note
    While the service processor in the blade server is initializing and synchronizing with the management module, the power-on LED flashes rapidly, and the power-control button on the blade server does not respond. This process can take approximately two minutes after the blade server has been installed.
  • The BladeCenter unit blowers are correctly installed and operational.

If these procedures do not solve the problem, it is likely a problem with the blade server. See Power error messages and Power problems.
