Hi,
ASR 1002x can operate using only one power supply. The second power supply is for redundancy and is not mandatory to have.

Hi
Is there any risk to switch on ASR1002x chassis with one power supply? will it fail if the second power supply not inserted ?

Hello,
It will work normally. Also the power supply is hot pluggable, so it will work if you insert it without interuption.

Two power supplies are used for redundant operation. System total power consumption shall never exceed rating of one power supply to maintain redundancy.
Two power supplies must be installed in the chassis at all times to ensure sufficient cooling. The system fans are inside the power supply units and must spin for cooling. Because all the system fans can be powered by one power supply, the second power supply unit does not have to be powered on, but it must be installed.
Please refer the Maintenance and operation guide for further details:

If a power supply is removed, the system can run with only one power supply for a maximum of five minutes. The router waits five minutes before shutting down. This five-minute window allows time to replace a failed power supply.
