The command output displays which Control Board is master and standby. Additionally,
the command output displays the Control Board state, redundancy status, temperature,
power source, and circuitry revision level for each Control Board installed in the router
chassis. CB1 is shown in standby mode, and is the redundant Control Board.
To display the environmental status of a particular Control Board, use the following
command:
t640@host> show chassis environment cb slot
To obtain the status of the redundant Control Board.
If you are near the router, physically look at the craft interface for the Control Board LEDs.
To display redundant Control Board status from the craft interface, use the following
command:
user@host> show chassis craft-interface
t640@host> show chassis craft-interface

The CB LEDs section of the command output indicates the status of the redundant Control
Board. An asterisk (*) indicates the current operating state:
and (Master). In the above output, no redundant Control Board is installed—the
Blue
output under CB1 is blank.
To check the LED status of the redundant Control Board.
To check the redundant Control Board LED status, look at the three LEDs located on the
Control Board faceplate.Table 150 on page 672
