General Troubleshooting Tips
Table C-1 lists general troubleshooting tips.
Note You must always have two power supplies installed on the Cisco ASR 1000 Series Routers to ensure
sufficient cooling for the box. The system fans are inside the power supply and must spin for cooling.
Since all the system fans can be powered by one power supply, it is not required for the second power
supply to be powered on, but it must be installed.

System fails to boot up
properly
If your system has power, check the STATUS LED on the ASR 1000
Series route processor and make certain all connections are secure.
See Table 2-8 for more information about the LEDs.
Power problems If the two power supplies are both showing GREEN on their Output
LEDs, then a failure of one power supply will not result in a system
failure.
Only one operating power supply is required for the Cisco ASR 1000
Series Router system to operate. Having only one supply powered is
a supported configuration. If both supplies have an OUTPUT FAIL
LED red, then the system will fail.
