NV8500 family Digital Routers • User’s Guide 1
1. Introduction
The NV8500 family is a series of highly flexible high-density routers supporting Standard Defini-
tion (SD), High Definition (HD) and 3.0 Gb/s (3Gig) video signals, and AES Asynchronous audio
signals. This section provides an overview of the NV8500 family of routers, including signal flow
and rates, power supply, active cards and frame expansion. It is recommended that you read this
section before starting any installation tasks.
Product Overview
The NV8500 family is composed of several routers that are either standalone routers or routers that
can be connected together to create larger switching matrices called “expandable” router frames.
Expandable router frames are denoted by the word “Plus.” A fully non-blocking matrix architecture
allows for one-to-one and one-to-many routing. Because inputs and outputs are independent, con-
figurations do not have to be numerically squared or identical in number.
Standalone routers allow for configurations as small as 9 inputs and 18 outputs, increasing in incre-
ments of 9 inputs or 18 outputs. Expandable routers allow for configurations as small as 9 inputs
and 9 outputs, increasing in increments of 9 inputs or 9 outputs. When two routers are connected
together, the number of inputs and outputs that can be switched doubles. The two connected routers
are considered a single matrix.
The following is a list of routers within the NV8500 family.
Input cards, output cards, control cards, crosspoint cards, monitor cards, and power supply modules
are “hot swappable” and installed through the front of the frame for easy access. The rear of the
router features a back plate into which backplanes housing different types of connectors for receiv-
ing and distributing signals are installed. Each backplane receives or distributes signals for a single
card allowing for maximum switching configuration flexibility. The back plate also contains con-
nections to system functions, such as a router control system, alarms or reference signals.

Product Overview
Mounting
The NV8500 family router frames mount in a standard 19″rack. The frame heights are as follows:
NV8576, NV8576-Plus 32RU 55.97″1.422 m
NV8280, NV8280-Plus 16RU 27.97″0.710 m
NV8144 8RU 13.97″0.355 m
The depth of each frame is approximately 17″. With 3″clearance for cabling, the minimum mount-
ing depth is approximately 20″. Doors add 0.8″of depth.
When placing the rack in your facility, be sure to leave enough space for air flow through the front
and rear of the router and within easy access of an AC power source. For installation instructions,
see Rack Mount on page 49.
Fuses
Routers in the NV8500 family have no user-serviceable fuses.
Cooling
Router frames in the NV8500 family have one or more fan trays providing forced air cooling
through five speed-controlled fans. In the NV8144, NV8280 and NV8280-Plus frames, a single fan
tray is located at the top of the chassis. For the NV8576 and NV8576-Plus frame, there are two fan
trays: one located at the top and one located at the bottom of the chassis. Fan trays are accessed
from the front of the frame. The fans draw cooling air from the center-front of the router, through
the door, and exhaust it through the rear of the frame at the top and bottom. The router must have
the door correctly installed and closed for proper airflow through the chassis.
Each fan features speed control which spins the fan at the optimal rate required to ensure that a con-
stant temperature is maintained within the router. Temperature sensors on the fans sense the exiting
temperature and increase or decrease the speed of the fan as required. By rotating only as required
to meet cooling needs, fan noise is significantly reduced in partially loaded frames or in environ-
ments with lower ambient temperatures. Maintaining a constant temperature also increases cir-
cuitry life span.
Each fan features two LEDs that indicate if the fan is receiving power and if there is a failure. For
more information, see Indicator LEDs on page 101.
There is a removable air filter located on the inside of the door assembly. It is recommended that
maintenance filters be performed on a regular basis. For more information, see Air Flow on page
103.
Caution If airflow is impeded, overheating may occur.

1. Introduction
Power Supply
Power Supply
Power for the NV8500 family routers frames is supplied through the Miranda PS8100 power sup-
ply module. The module is either installed in the router frame (the NV8144) or installed in an exter-
nal, separate frame, the NV8000. The NV8000 can house up to 4 modules. Each PS8100 module
produces 850 Watts.
The number and type of power supply modules required, and if and how many NV8000 power sup-
ply frames are required, depends on which and how many routers are being used. For redundancy,
additional (optional) power supply modules can be installed as a backup power source should the
primary module fail. For a list of power requirements, see Connecting to Power on page 85.
The PS8100 power supply module accepts a wide range of AC input voltages and produces five
+48 VDC outputs. The power supply automatically senses the AC input voltage range (90–130 and
180–250 VAC) and adjusts to maintain a relatively constant DC output; no voltage selection 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 output powers one of the five green LEDs and
output test points located on the front of the PS8100 power supply module. Under normal opera-
tion, all five LEDs are lit. For more information on LEDs, see Indicator LEDs on page 101.
Figure 1-1 shows the PS8100 power supply module architecture.
Figure 1-1. PS8100 Power Supply Module Diagram
For information on making power supply connections, see Connecting to Power on page 85.
The PS8100 power supply module, and the NCV8000 power supply frame, have no serviceable
fuses.
Cooling is provided by a single low-speed fan located along the front edge of each PS8100 power
supply module, which draws a small quantity of air across the internal heat sinks.

Signal Rates and Flow
Signal Rates and Flow
Routers in the NV8500 family support SD, HD and 3Gig video signals, and AES3 Digital Audio
Asynchronous audio signals, both balanced and unbalanced. The following table lists the standards
and rates for each signal type. HD signals are managed through active 3Gig cards. Embedded audio
signals are passed through. For a description of each card and corresponding part numbers, see
Input Cards on page 38 and Output Cards on page 40.
Reference signals are required for proper switching of video signals. See Video Reference on page
35. No reference is required for AES3 Digital Audio Asynchronous signals.
Product Overview on page 1
Signal Flow
Routers 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 37.
Standalone Routers
The NV8500 family standalone routers include the NV8144, NV8280 and NV8576. The NV8144
can house two 144 x 144 crosspoint cards (one required and one optional for redundancy).
The NV8280 and NV8576 router frames each house up to 8 crosspoint cards and an optional redun-
dant crosspoint cardset (a single module). The NV8280 crosspoint cards having a switching matrix
of 144 x 144 and the NV8576 crosspoint cards have a 288 x 288 matrix. The crosspoint card slots
are numbered 1 through 10, from left to right. An optional redundant crosspoint cardset can be
installed in slots 5 and 6. All other crosspoint cards are installed in slots 1 through 4 and slots 7
through 10. The 8 crosspoint cards are divided into 2 sets of 4, with each set of 4 fanning out and
distributing inputs to all outputs.
Each standalone router switches signals via the crosspoint card differently. In a fully loaded
NV8144 frame (i.e., all active cards installed), all inputs are sent to the crosspoint cards for distri-
bution to any or all outputs.
In a fully loaded NV8280 or NV8576 frame, inputs on the left side of the frame (when facing the
front of the router) are forwarded to crosspoint cards 1, 2, 7 and 8. Inputs situated on the right side
of the frame are forwarded to crosspoint cards 3, 4, 9 and 10, as shown in Figure 1-2 on page 6. All

inputs are also forwarded to the optional redundant crosspoint cardset. The optional redundant cros-
spoint cardset feeds any input to any output depending on which active crosspoint card it is taking
over for.
Outputs are distributed from each crosspoint card to specific output cards such that crosspoint cards
in the left side of the frame (when facing the front of the router) feed output cards located in the left
side of the frame. Similarly, crosspoint cards in the right side of the frame feed output cards located
in the right side of the frame, as shown in Figure 1-3 on page 7.

As an example, NV8576 has 8 crosspoint cards that each manage up to 288 × 288 signals and are
divided into 2 sets of 4, with each set of 4 fanning out and distributing 288 inputs (1–288 and 289–
576) to all 1152 outputs. In a fully loaded frame, inputs 1–288 on the left side of the frame (when
facing the front of the router) are forwarded to crosspoint cards 1, 2, 7 and 8. Inputs 289–576, situ-
ated on the right side of the frame, are forwarded to crosspoint cards 3, 4, 9 and 10. (See Figure 1-2
and Figure 1-3 on page 7.)

Expandable Routers
Expandable routers in the NV8500 family (NV8280-Plus and NV8576-Plus) can be used as a stan-
dalone router or connected to an identical router to increase the switching matrix. The signal flow
of inputs and outputs in an expandable router is identical to a standalone router, with one exception:
signals are being received from or distributed to a connected router. When two expandable routers
are connected, signals from one router are distributed to the second connected router, and vice
versa, through expansion connections and expansion output cards. Each output only goes through a
crosspoint card once. Before an output is forwarded to a connected router, it first goes through the
crosspoint card on the local router for switching to the expansion connections through which it is

sent to the second router. From the expansion connection on the first router, the signal is sent
directly to the corresponding expansion connection on the second router and then directly to that
output card.
Figure 1-4 illustrates the signal flow for two connected NV8576-Plus routers. Outputs 577–864 on
the first router (Router 1) through the output connections to the second router (Router 2) and the
reverse flow of signals between the two routers.

Slots and Corresponding Signal Numbers
Signals are received and distributed through I/O cards and connectors housed on a backplane. The
I/O card and number and type of connectors varies depending on whether the signal is an input or
output, and whether the frame is a standalone router (NV8144, NV8280 or NV8576) or in
expanded mode and connected to a second router frame (NV8280-Plus or NV8576-Plus).
Each signal is assigned a number that corresponds to the physical input or output connector and to
the slot in which an input card or output card is installed. In the NV8500 family, each backplane in
a standalone frame contains either 9 input connectors or 18 output connectors. (See Backplanes on
page 29.) This means that in the standalone router frame, Input Slot 1 corresponds to inputs 1–9,
Input Slot 2 corresponds to inputs 10–18, and so on, up to the maximum. Output slots are similarly

numbered with Output Slot 1 corresponding to outputs 1–18, Output Slot 2 to outputs 19–36, and
so on.
Each card inserted in a slot manages a range of numbers. However, when making physical connec-
tions on the backplanes, each connector has a specific signal number assigned. For details on signal
numbering on backplanes, see Backplane Connectors and Individual Signal Numbers on page 59.
Figure 1-5 shows the standalone NV8576 frame and which signal numbers correspond to which
slots when viewing the router from the front.

Expandable Frames and Signal Numbers
Expandable router frames contain backplanes similar to the standalone routers except that the con-
nectors housed on the backplanes are different. Each backplane contains either 9 input connectors
or 9 output connectors plus two high-density expansion connectors. This means that input slot 1
corresponds to inputs 1–9, input slot 2 corresponds to inputs 10–18, and so on, up to the maximum.
For outputs, output slot 1 corresponds to local outputs 1–9 and forwards through the expansion
connectors outputs to the second router, and so on. For example, in the NV8576-Plus frame, output
