2. Introduction
Chapter 2 provides an introduction to the NV8288 and the NV8288-Plus Digital Video Routers. It
presents the following topics:
•Product Summary
•Signal Rates and Flow
•Power Supply
•Module Slots and Rear Connectors
•Active Cards
•Frame Expansion
Product Summary
The NV8288 and the NV8288-Plus are high-density digital video routers managing Standard Defi-
nition (SD-SDI) and High Definition (HD-SDI) signal routing. The routers can manage SD-SDI
separately or SD-SDI and HD-SDI signals combined, referred to as Super Wide Band (SWB)
throughout this manual. For signal rates, see Signal Rates and Flow on page 4.
Each router starts with a base configuration that can be increased incrementally, as follows:
• The NV8288 is a standalone router that can manage up to 288 inputs and 576 outputs. The
router cannot be connected to other routers. The router allows for configurations as small as 12
inputs and 12 outputs, increasing in increments of 12. Inputs and outputs do not need to be iden-
tical in number.
• The NV8288-Plus, as a standalone router, can manage up to 288 inputs and 288 outputs. In
addition, the NV8288-Plus has expansion connections enabling two router frames to be con-
nected together to manage up to 576 inputs and 576 outputs. The router allows for configura-
tions as small as 12 inputs and 6 outputs, increasing in increments of 12 inputs and 6 outputs.
The NV8288 and the NV8288-Plus have non-blocking architecture. This feature enables the distri-
bution of incoming signals to none, one, many or all outputs as desired.
Frame Rack
Both the NV8288 and the NV8288-Plus have 10 RU frames, 19″(482.6 mm) wide and 12″(305 mm)
deep. When placing the router in a rack in your facility, be sure to leave enough space for air flow
through the front of the router and within easy access of an AC power source. For installation
instructions, see Rack Mount on page 23.

2. Introduction
Signal Rates and Flow
Frame Cooling
The router has two fan trays housing three fans each. The fans draw cooling air from the front of
the router, through the door, and exhaust it through the rear of the frame. The router must have the
door correctly installed and closed for proper airflow through the chassis.
The fan trays are accessed from the front of the frame: one is located at the top of the chassis and
one at the bottom. There are also removable air filters located on the inside of the door assembly. It
is recommended that you perform regular maintenance on the fan trays and filters. For more infor-
mation, see Maintenance on page 55.
Signal Rates and Flow
Both the NV8288 and the NV8288-Plus support SD-SDI and HD-SDI signals. The routers can
manage SD-SDI or SWB. The following table lists the SMPTE, re-clocking and pass through rates
for each type of signal.
Signal Flow
The NV8288 and the NV8288-Plus switch incoming signals to designated output connections.
Switching is directed by settings configured in the router control system, which sends commands to
the control card. In turn, the control card directs how switching occurs on the crosspoint card. For a
description of control cards and crosspoint cards, see Active Cards on page 15.
NV8288
The NV8288 is a standalone router that can manage up to 288 inputs and 576 outputs. Figure 2-1
shows the flow of signals in the NV8288. Both top and bottom crosspoint cards receive all incom-
ing signals, up to 288 inputs. The top crosspoint card feeds signals to output cards located in the
upper half of the router frame: Outputs 1–144 and 145–288. The bottom crosspoint card feeds sig-
nals to output cards located in the bottom half of the router frame: outputs 289–432 and 433–576.
Caution If airflow is impeded, overheating can occur.

NV8288-Plus
The NV8288-Plus may be used as a standalone router capable of managing up to 288 inputs and
288 outputs or be connected to another NV8288-Plus router to double the number of inputs and
outputs managed to 576 inputs and 576 outputs.
As a standalone router, all incoming signals are sent to all installed crosspoint card(s). (Only one
crosspoint card is required in standalone mode, installed in the top crosspoint slot.) The crosspoint
card feeds outgoing signals to all output cards, up to 288 signals.
If two NV8288-Plus routers are connected together (Router 1, Router 2), each router must contain
two crosspoint cards, installed in the top and bottom crosspoint slots. On each router, incoming sig-
nals are sent to both the top and bottom crosspoint cards. The top crosspoint card feeds signals to
all output cards on the local router (router 1), up to 288 signals. The bottom crosspoint card feeds
signals to the connected router (router 2), up to 288 signals. This means that both routers are man-
aging up to 288 incoming signals and 288 outgoing signals for a combined total of up to 576 inputs
and 576 outputs.

router.
Figure 2-2. Signal Flow for NV8288-Plus (576 inputs and 576 outputs)
Power Supply
The power supply for the NV8288 and the NV8288-Plus is an external, separate frame. There are
two external power frames available: the NV62571and the NV8000. Each power supply frame
uses a specific power supply module that supplies power to the router frame.
Each external power frame uses the following module:
• The NV6257 uses the PS6000 power supply module and can house up to 8 modules.
• The NV8000 uses the PS8010 power supply module and can house up to 4 modules.
The power supply modules differ in the amount of power produced: The PS6000 produces 660
Watts while the PS8010 produces 875 Watts. Because the PS8010 produces a greater amount of
power, fewer modules are needed, reducing the frame size amount of facility space required.
The number of power supply modules required depends on which and how many routers are being
used. For redundancy, additional (optional) power supply modules can be installed.
The minimum number of required power supply modules are as follows:

2. Introduction
Module Slots and Rear Connectors
The PS6000 and PS8010 power supply modules accepts a wide range of AC input voltages and
produces five +48 VDC outputs. The power supply automatically senses the AC input voltage (90–
130 and 180–250 VAC) and adjusts to maintain a relatively constant DC output; no voltage selec-
tion is required.
The five regulated outputs are directed to modules in the router where on-board regulators produce
the DC voltages required by the local circuits. Each +48 VDC output powers one of the five green
LEDs and output test points located on the front of the PS6000 and PS8010 power supply modules.
Under normal operation, all five LEDs are lit. For more information on LEDs, see Indicator LEDs
on page 56.
Figure 2-3 shows the PS6000 and the PS8010 power supply module architecture.
Figure 2-3. Power Supply Module Diagram
For information on making power supply connections, see Making Power Connections on page 24.
Fuses
Fuses for AC power inputs are located on the PS6000 power supply modules. When an NV6257 is
ordered, fuses appropriate for line voltage in use at the country of destination are installed on the
PS6000 power supply modules. Be sure to check the fuse ratings for compliance with specific
requirements in your area. For information on replacing fuses, see Fuse Replacement on page 55.
The PS8010 power supply module has no serviceable fuses.
Power Supply Cooling
There are four low-speed fans located along the front edge of each PS6000 and PS8010 power sup-
ply module. They are intended to pull a small quantity of air across the internal heat sinks.
Module Slots and Rear Connectors
The NV8288 and the NV8288-Plus share common hardware features. Both provide slots for hous-
ing input, output, monitor, control and crosspoint cards. Similarly, both feature non-interchangeable
backplanes that house connectors for incoming and outgoing signals. Both also share common sys-
tem connections. However, the NV8288-Plus has unique output cards and output signal connec-
tions that enable two NV8288-Plus routers to be connected together to create a system capable of
managing 576 inputs and 576 outputs.

for input cards and output cards. In the upper bay are two additional slots for two control cards. In
the lower bay are two additional slots for one monitor cardset (composed of two monitor cards).
Slots contain color-coded card guides that match the color of the ejector lever on the card that is
installed in that slot. For more information, see Active Cards on page 15.
Located in the center of the router are two horizontal slots housing two crosspoint cards. At the top
and bottom of the router frame are two removable fan trays.
Each input card slot and output card slot, and the card it holds, manages signals received or distrib-
uted through 12 connectors. Each signal is assigned a number that corresponds to the physical input
or output connection. This means that Output Slot 1 corresponds to outputs 1-12, Output Slot 2 cor-
responds to outputs 13-24, and so on, up to 576. Similarly, Input Slot 1 corresponds to inputs 1-12,
Input Slot 2 corresponds to inputs 13-24, and so on, up to 288.

For information on installing cards in module slots, see Installing Active Cards on page 33.
Figure 2-5 shows the rear of the NV8288. The rear contains non-interchangeable backplanes con-
taining 864 I/O DIN 1.0/2.3 connections: 288 for receiving signals and 576 for distributing signals.
Note that the outputs and inputs are numbered from right to left because the router is being viewed

Figure 2-6 on page 10 shows the front of the NV8288-Plus with the door removed. From this view,
in the slots that do not have an active card installed, the backside of installed backplanes and the
motherboard connectors are visible. The router features 36 upper bay slots and 36 lower bay slots
for input cards and output cards. In the upper bay are two additional slots for two control cards. In
the lower bay are two additional slots for one monitor cardset (composed of two monitor cards).
Slots have colored guides that match the color of the ejector lever on the card that is installed in that
slot. For more information, see Active Cards on page 15.
Located in the center of the router are two horizontal slots housing two crosspoint cards. At the top
and bottom of the router frame are two removable fan trays.
Inputs are numbered 1–288 with each card slot, and the card it holds, corresponding to 12 input
connections. This means that input slot 1 corresponds to inputs 1–12, input slot 2 corresponds to
inputs 13–24, and so on, up to 288.
Outputs are numbered 1–288 also, but each card slot contains two types of output connections: 6
connections for outgoing signals for the local router and one expansion connection for outputs to a
connected NV8288-Plus router. This means that output slot 1 corresponds to outputs 1–6, output
slot 2 corresponds to outputs 7–12, and so on, up to 288.

2. Introduction
Module Slots and Rear Connectors
If the NV8288-Plus router is used as a standalone router, only the 6 local outgoing signal connec-
tions are used. If the router is connected to another NV8288-Plus router, each expansion connection
send signals to the connected router, as follows: output slot 1 sends outputs 289–294 to the con-
nected router, output slot 2 sends outputs 295–300 to the connected router, and so on, up to 576.
Similarly, the connected router sends outputs to the local router in the same manner, doubling out-
puts. Inputs are also doubled, so that the two routers have a combined total of 576 inputs and 576
outputs.
