Power Supply Modules
The system supports two 400W power supply modules accessable at the
front panel. These two modules allow hot-swapping in the event one of the
modules fails. The power supply fault LED lights and an audible alarm
sounds when a module experiences a failure. If the error does not require
the replacement of a power supply module, reset the alarm with the power
supply alarm reset switch on the front panel (see the illustration Front Panel
on page 23 for the location of the LED and switch).
If the failure requires you to replace the failed module, turn off the failed
module and follow the instructions below to replace it.
1.
Through the operating system, ensure that the server is not attempting
to draw power from the failed module and prepare to replace the
module. Specific instructions should be provided by the operating
system or utility software documentation.
2.
Turn off the power to the failed power supply module. You may leave
the power to the other module on.
