Figure 2-12 Power Supplies and Indicators
Both power supply canisters have a built-in sensor that detects the following conditions:
• Over-voltage
• Over-current
• Overheated power supply
If any of these conditions occurs, one or both power supplies will shut down. All power
remains off until one of the following occurs:
• You cycle the power switches (turn the power switches off, then turn them back on).
See "Overtemp Condition and Power Supply Shutdown" on page 31 for more
information on recovering from an overtemp condition.
• The power supplies automatically resume operation when the ambient air
temperature cools to below 70º C (158º F). When the power supplies automatically
resume operation, the controller also will resume operation.
After one of these occurs, then an automatic restart resets the controllers, attempts to spin
up the drives (which has no effect on the drives if they are already running), and returns
the controller enclosure to normal operation without operator intervention.
