Overtemperature condition and power supply shutdown

If the fan and communications module fails or is unable to maintain an internal
temperature below 70
might shut down (see
not operational.

The storage-management software causes the fault indicator to light before the
temperature has risen sufficiently to shut down the power supplies. The light comes on
when the controller unit temperature exceeds 45° C (113° F). The controller unit shuts
down if the temperature rises to 70° C (158° F). See
controller fan fault indicator. If both power supplies shut down, the fault indicator cannot
come on.
