1. Introduction
Front Module Slots and Rear Connections
Backplanes
The rear of the NV8500 family of routers feature rear backplane modules. Each backplane contains
connectors that receive or distribute signals. Each signal type requires a specific connector and
backplane. For example, fiber optic signals require backplanes housing LC connectors. Different
types of backplanes can be combined in a single router frame. This enables you to meet different
signal and cabling requirements in a single router frame.
The type of backplane installed depends on the signal being managed and whether the router is a
standalone or expandable router. There are different backplanes for different tasks. Certain back-
planes are used for receiving inputs or distributing outputs, other backplanes receive or distribute
signals for monitoring purposes, and when two expandable router frames are connected, unique
backplanes manage the distribution of signals between the two frames.
Backplanes containing DIN 1.0/2.3 or terminal block connectors are passive while backplanes with
LC connectors have active circuitry.
For proper operation, each backplane must match its corresponding input card, output card, or mon-
itor card. For example, if a backplane is to receive coaxial input signals, then a coax input card
must be installed in the corresponding card slot. For a description of each type of active card, see
Connectors on a backplane differ depending on the signals being managed and whether the router is
being used in standalone or expanded mode.
