safety margin for unexpected losses.
Table 89 on page 166 lists the specifications for the cables that connect to management
ports and the wires that connect to the alarm relay contacts.
NOTE: 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.
