Maintaining the MX2010 Power Usage
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.
