has been tripped
Check the power supply-fan unit power switches,
circuit breakers, and AC power source.
If none of these sources are the cause of the
fault, then do not replace the failed power
supply-fan unit until you have performed additional
diagnostics to determine why the Service Action
Allowed LED on the power supply-fan is not lit.
Call IBM Support if needed.

Use DS4000 Storage Manager client software to
place the controller online. It the failure persists,
do not replace the controller unit. Instead, perform
additional diagnostics (such as checking the
power supply-fan components) to determine what
additional failures have caused the associated
