General Troubleshooting Tips

Read the following general troubleshooting tips you might encounter at startup.

Note You must always have two power supplies installed in the Cisco ASR 1000 Series routers to insure 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.

properly

Series RP1and make certain all connections are secure.

 

 

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 a 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.
