    M320 Router, T320 Router, T640 Router, and T1600 Router Redundant Host Subsystems

    On the M320 router, T320 router, T640 router, and the T1600 router, the host subsystem consists of a Routing Engine and Control Board functioning as a unit. Two host subsystems can be installed in each routing platform. One pair functions as master, while the other stands by as backup should the master Routing Engine fail. (See Figure 1.)
