Troubleshooting the AC Power Supply Installation
Use the following procedure to troubleshoot the AC power supply if it is not
operating properly after installation.
Step 1 Make sure the power supply is seated properly:
• Eject and reseat the PEM. Make sure:
– The captive screw on the ejector lever is tightened securely.
– The power switch is set to the on (1) position.
Step 2 Make sure the router is powered on and that all power cords are connected
properly:
• Power cords on the horizontal trough are secured in place with their retention
clips.
• Power cords at the power source end are securely plugged into their own
AC power outlet.
Each AC power supply operating in the nominal range of 200 to 240 VAC
requires a minimum service of 20 A, North America (or 13 A, international).
• Source AC circuit breaker is switched on.
Step 3 Check the power supply status indicators:
• Pwr OK (green)—Indicates that the power supply is operating normally, and
the source AC voltage is within the nominal operating range of 200 VAC to
240 VAC. This indicator lights when the power supply switch is set to the on
(1) position.
– If the Pwr OK indicator remains off after checking all of the power
sources, replace the power supply with a spare.
– If the spare power supply does not work, replace its PDU.
