What It Means 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.
Alternative Action To display the environmental status of a particular Control Board, use the following
JUNOS CLI operational mode command:
