What It Means

The command output displays the Control Boards installed in the router chassis, including the slot number, revision level, part number, serial number, and a brief description of the component. Give this information to the Juniper Networks Technical Assistance Center (JTAC) if a Control Board fails. The command output for this T640 routing node shows that two Control Boards are installed. By default, CB1 is the redundant Control Board.
