    M320, T320, T640, T1600, TX Matrix, and TX Matrix Plus Router Control Board Location

    You can install one or two Control Boards in the router. The Control Boards install into the upper rear of the chassis in the slots labeled CBO and CB1 (see Figure 1 for M320, T320, T640, and T1600 router Control Board location and Figure 2 for TX Matrix and TX Matrix Plus router Control Board location).

    Each Control Board requires that a Routing Engine be installed in the adjacent slot. CB0 installs above RE0, and CB1 installs below RE1. A Control Board does not function if no Routing Engine is present in the adjacent slot.

    If two Control Boards are installed, one functions as master and the other acts as backup. If the master Control Board fails or is removed, the backup restarts and becomes master.

    The Control Boards are hot-pluggable.
