Troubleshooting the AC-Input Power Subsystem
• Power switch on the front panel is set to the ON position.
Step 2 Make sure the router is powered on and that all power cords are connected properly. Verify that:
• Power cables are securely attached to their power module terminal studs.
• Power cords at the power source end are securely plugged into their own AC power outlets.
• Source AC circuit breaker is switched on.
Step 3 Check the power supply status LED indicators:
• Cisco ASR 9901:
Note
• OK Power LED—Indicates that the input AC power is OK, or indicates a power supply failure
• Cisco ASR 9001:
• OK (green) Power LED—Indicates that the input AC power is OK.
• FAIL (amber) LED—Indicates the power supply failure, includes over voltage, over current, over

(includes over voltage, over current, over temperature and fan failure conditions).
Solid green LED indicates AC power input is operating normally, and the source AC input voltage
of 100 to 240 VAC is within the nominal operating range.
Blinking green LED indicates the power supply is connected to input power source but not outputting
power to the router.
Blinking amber LED indicates alarm condition or power supply warning events, while the power
supply continues to operate; this includes high temperature, high power, or slow fan conditions.
Make sure that each power cord is connected to a dedicated AC power source. Verify that each AC
power source is operating in the nominal range of 100 to 240 VAC and is supplying a minimum
service of 15 A, North America (or 10 A, international).
Solid amber LED indicates a power supply failure due to over voltage, over current, over temperature,
