Power Supply Problems
If, during testing, the power supply is not working properly please check the
following:
• Verify all the connectors are plugged in properly (correct pinouts, loose
connections, wrong direction).
• Make sure the module is in the right position.
• Check for short-circuits or defective peripherals by unhooking each
peripheral one at a time.
If you hear the warning buzzer or see the system LED flashing, please check the
following:
• Make sure the individual module power switch is in the ON position.
• Verify the load is over the minimum/under the maximum load for each
channel.
• Check that each power cord is securely plugged into the inlet.
• If necessary unplug the power cords, wait 2 or 3 minutes for the protection
state to release, test it again.
• If the buzzer or LED still indicates that the unit is defective, locate the
defective power module and replace it with a new one by performing the
hot-swap procedure.

load conditions the power module is around 122°F to 140 °F (50°C to 60°C).
