Symptom
Cause
Recommended action
Ops panel fault LED for drive module faults
Module fault LED is on
and a carrier fault LED
is on
A fault condition
related to the
hardware in the front
or rear panel areas
1. Inspect the LEDs on the carriers for these conditions:
l
Both carrier LEDs are off.
l
A fault amber LED is on, not flashing.
2. Select one of the following actions:
l
Reseat the drive module in its carrier (DDIC).
l
If both LEDs are off, verify that the DDIC is fully inserted, the
latch is fully engaged, and the storage enclosure is powered on.
l
If the fault LED is on, narrow the fault to the drive module, the
carrier, a connection, or both.
3. Scan the enclosure event log for specific fault information and follow
recommended actions.
4. If the above actions do not resolve the fault, replace the faulty drive
module or carrier as soon as you have a replacement.
Ops panel fault LEDs that identify rear panel area faults
Module fault LED is on
and a controller
module (CM) fault LED
is on
,
A fault condition
related to the CM
hardware in the rear
panel area
1. Restart the CM with a CLI or WBI command.
2. Confirm the redundant CM is properly functioning.
3. Select one of the following actions:
l
If both CMs are failing, follow shut down instructions and power
off the system enclosure by removing power to both PCMs. Do
not power on until after you successfully replace them both.
l
If one CM is failing, remove power, wait 1 minute, then reset the
CM.
4. If the CM is still failing, and the failure is related to a CM host port,
follow the steps associated with system application faults below.
5. If the CM is still failing, remove the power cord, wait 1 minute, then
reseat the CM .
6. If the CM is still failing, replace it within the specified 8 minutes with a
new one.
7. If installing a new CM that is still failing, remove it, inspect
connections for bent pins, reinstall it, then check the event log for
errors.
Module fault LED is on
and
one or more power
cooling module (PCM)
fault LEDs are on
,
,
A fault condition
related to the PCM
1. Verify AC mains connections to the PCM are live.
2. Confirm the redundant PCM is properly functioning.
3. Select one of the following actions:
l
If both PCMs are failing, follow shut down instructions and power
off the system enclosure by removing power to both PCMs. Do
not power on until after you successfully replace them both.
l
If only one PCM is failing, either power cycle the PCM and wait 1
minute or remove the power cord, wait 1 minute, then reseat the
power cord.
4. If the PCM still fails, remove it, wait 1 minute, then reseat it.
5. If the PCM still fails, replace it within the specified 10 minutes.
6. If the power fault condition persists, contact your vendor for support.
