Overtemperature condition and power supply shutdown
If the fan and communications module fails or is unable to maintain an internal
temperature below 70
o
C (158
o
F), one or both of the power supplies in the controller unit
might shut down (see Figure 12 ). If both power supplies shut down, the controller unit is
not operational.
Figure 12. Fan and communications and power supply fault indicators
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
Figure 13 for the location of the
controller fan fault indicator. If both power supplies shut down, the fault indicator cannot
come on.
