Chapter 5 Maintaining the Router

Removing and Replacing AC and DC Power Subsystem Components

•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).
