Use this procedure to regain normal system operation after a power supply shutdown.
1. If your controller enclosure shuts down unexpectedly, use the storage management
software (TPSSM7) to determine if the controller enclosure has overheated. If an
overtemp shutdown is indicated, continue with the following steps.
2. Remove the rear access panel on the rack.
3. Turn off the power switches and do whatever is necessary to cool the controller
enclosure (replace the fans, use external fans to cool the room, and so on).
Warning:
Risk of electrical shock! Never turn on the power to any equipment if
there is evidence of fire, water, or structural damage. If there is evidence of
damage, call the factory or appropriate service organization for assistance.
Depending on the current service agreements, you may or may not need to return
the unit for repair/replacement.
4. Once the air temperature is below the upper operating temperature of 45˚ C (113˚ F),
turn on both power switches on the rear of the controller enclosure (Figure 3-2). You
must turn on both switches to take advantage of the redundant power supplies.
Then, go to "Checking the Controller Enclosure Indicator Lights" on page 36.
