Meaning
The command output lists the Control Board state, redundancy status, temperature, power supply voltages, and circuitry revision level. If you do not specify a Control Board slot number, the command displays the environmental status for each Control Board installed in the router chassis. If you specify a Control Board slot number, the command displays the status for that slot only.
