• 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).
