2. Introduction
Module Slots and Rear Connectors
ond set of Standard SWB main output cards and expansion output cards can be installed, increasing
the switching configuration to 128 inputs x 128 outputs.
The Standard SWB cards must be installed in specific router slots. For installation instructions, see
Installing Other Video, Audio and Time-Code Backplanes
on page 43. For more information about
card architecture, see
Machine Control Switching Configurations
The machine control card set is composed of two cards connected together that occupy two card
slots. The machine control card set is bidirectional; it carries signals in both directions (input and
output).
A single machine control card set can support 32 ports. If a second machine control card set is
installed and combined with the first card set, the configuration can be doubled to 64 ports.
The Machine Control cards must be installed in specific router slots. For installation instructions,
see

Module Slots and Rear Connectors
The NV5128 has slots for input cards, output cards, and control cards. Cards are installed through
the front of the frame for easy access and are “hot swappable”. The rear of the router is a back plate
into which backplanes housing connectors for receiving and distributing signals are installed. The
back plate also contains connections to system functions, such as a router control system, alarms or
reference signals.
Active circuitry is contained mainly on the input cards, output cards, control cards, power supply
modules, and fan tray installed through the router’s front. However, some active circuitry for SD
and HD signals are located on the associated backplanes, which are installed through the router’s
rear. All cards and backplanes are “hot-swappable.”
An internal motherboard spans the frame and interconnects front and rear modules, and distributes
control signals, timing information, and power. Cards, power supply modules, and the fan tray plug
into the motherboard from the front of the router and backplanes plug into the same motherboard
from the rear. Each input card and output card has a corresponding backplane. For more informa-
tion on each type of card, see
on page 21. For more information on backplanes, see
Front Slots
Figure 2-3, next page, shows the front of the NV5128 with the door removed. In the center of the
router are eight slots designated for input cards. To the right and left of the input slots are four slots
designated for output cards. On the far right, two slots house the primary and secondary control
cards. A fan tray is located at the top of the router chassis.
Viewing the frame from the front, slots are numbered 1 through 16, from left to right. (See
Figure 2-3.)
