Procedure
Check the power LEDs on both controller
modules. If a Power LED is off, make sure
that the module is plugged in correctly and
its handles are locked in place.
If the Fault LED remains on after replacing
the controller, go to cause C.
Replace the memory modules.
If the Fault LED remains ON after replacing
the memory, go to cause D.
Replace the midplane. If the Fault LED
remains ON after replacing the midplane,
call the factory service center.
Check the Fan Fault LED on the front cover.
If it is on, go to Troubleshooting Controller
fan module Problems. If not, continue at the
next step. Replace the failed controller.
Check both controllers for fault LEDs, then
replace the failed controller.
After replacing the failed controller, check
the LEDs on the front cover. If the Fan Fault
LED is still on, replace the controller
module.
