Routing Engine Interface Cable and Wire Specifications for MX Series Routers
Table 1 lists the specifications for the cables that connect to management ports and the wires that connect to the alarm relay contacts.
In routers where the Routing Engine (RE) and Control Board (CB) are integrated into a single board, a CB-RE is known as Routing and Control Board (RCB). The RCB is a single FRU that provides RE and CB functionality.
