• Fault (yellow)—Indicates that the system has detected a fault within the

power supply. This indicator remains off during normal operation.

If the indicator is on:

–

Toggle the power switch off and then on. If the indicator remains on after

several attempts to power it on, replace the power supply with a spare.

–

If the spare power supply also fails, the problem could be a faulty power

shelf backplane connector. Power off the router and contact a Cisco

service representative for assistance.

• Temp (yellow)—Indicates that the power supply is in an over-temperature

condition, causing a shut-down to occur.

–

Verify that the power supply fans are operating properly.

–

Verify that the blower module is operating properly.

–

If the power supply fans and the blower module are operating properly,

replace the existing power supply with a spare.

• Ilim—Indicates the power supply is operating in a current-limiting condition.

–

Each power cord should be connected to a dedicated AC power source.

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).
