arrow_forward

Purpose

For optimum router performance, verify the AC or DC power usage.

Action

On a regular basis:

Make sure that the total system power consumption and capacity does not exceed the maximum allocated.
- Issue the show chassis power command to display the information about the AC or DC power system.

The following output displays the AC chassis power for 2500 W capacity.
