IOM LEDs

IOM LEDs pertain to controller modules and expansion modules, respectively. Expansion enclosures are supported for
optionally adding storage. See also

Actions:
• If the CRU OK LED is blinking, wait for the system to boot.
• If the CRU OK LED is off, and the IOM is powered on, the module has failed.
Check that the IOM is fully inserted and latched in place, and that the enclosure is powered on.

Check the event log for specific information regarding the failure.

• If the CRU Fault LED is on, a fault condition is detected.
Restart this controller from the partner controller using the SMC or CLI.

If the restart does not resolve the fault, remove the IOM and reinsert it.

• If the above actions do not resolve the fault, contact your supplier for assistance. IOM replacement may be necessary.
Expansion module LEDs
Expansion IOM status is monitored by the LEDs located on the face plate. See also

Temperature sensors

Temperature sensors throughout the enclosure and its components monitor the thermal health of the storage system.
Exceeding the limits of critical values will cause a notification to occur.
