PRODUCT OVERVIEW
SVSi’s N2000 AV over IP Series provides a flexible, feature-rich, and simple-to-deploy digital media
distribution and switching solution satisfying the most demanding applications. SVSi video over IP Encoders
are used to encode and distribute sources of almost any format onto an existing IP network, making that
stream available to any endpoint in the facility. Video over IP Decoders are used to decode SVSi’s Networked
audio/video (AV) streams back to DVI or HDMI format for display on any monitor. With the ability to direct any
source stream to any display, large, low-cost switching and distribution systems are simple to deploy without
proprietary cabling or dedicated switching hardware. Plug-n-play, auto-detect technology reduces installation
and programming time.
Features include:
1080p/60Hz encoding and decoding (applies to N2141 and N2241).
Backwardly compatible with SVSi’s V-Series products.
Input and Output Scaling scaling performed in Encoders or Decoders for maximum flexibility
with V-Series sources and displays.
Power over Ethernet (PoE) – eliminates the need for a local power supply and speeds
installation. Units can still be powered locally by 12VDC. This allows easy rack-mountable,
high-density installations. (All units can be PoE powered except the N2211 Decoder.)
Infrared (IR) emitter connection allows control of low-cost, IR-only display devices.
Fast install with Phoenix connectors for power, IR, RS232 serial, and analog audio interfaces.
Pass-through DVI interface allows easy installation with local display, such as desktop PC
applications.

INTRODUCTION
This chapter provides an installation overview as well as a detailed step-by-step process for installation.
INSTALLATION OVERVIEW
The N2000 Encoders and Decoders have multiple configuration and installation options. For basic installation
guidelines, see Table 2-1
. For more detailed instructions, refer to Step-by-Step Installation Instructions on
page 20.
Table 2-1. Basic Installation Guidelines
Connections Options
Power
Power over Ethernet (PoE): Connect the unit’s P0 port to an active, PoE-enabled
network switch (not supported on the N2211 Decoder).
External power supply: If not using PoE for power, connect a 12V regulated power
supply (SVSi part number N9312) to the unit’s two-pin terminal block plug connector
labeled +12V 2A.
Network
PoE units: If using PoE to power the unit, you should already have a network
connection.
Externally powered units: If not using PoE, connect either the P0 or P1 port to the
network using an Ethernet cable.
Daisy-chain configuration: Once network connection is established to one unit,
you can daisy chain additional units by connecting Ethernet cables between devices
using their P0 and/or P1 ports. Keep in mind that the number of units supported in
this configuration is limited by bandwidth (total aggregate streams must be less than
1 Gb/s).
Note: PoE power is only supplied to the unit connected directly to the network
. All
other units in the daisy-chain must have an external power supply.
Video
N2000 Encoders
• For video encoding of a digital source, connect the source to the Encoders DVI-D
port using a video cable with a DVI-D connector (or adapter).
• For video encoding of a digital or analog source, connect the source to the

Chapter 2. Installation Mounting Options
MOUNTING OPTIONS
The N2000 units are available in stand-alone and card versions. The stand-alone version can be free
standing, surface mounted, wall mounted, or rack mounted. All cards must be rack mounted using the N9206
Card Cage (sold separately).
Surface and Wall Mounting
To mount your N2000 stand-alone unit to a flat surface or wall, follow these steps:
1. Remove the four screws from the bottom of the unit and use them to attach the mounting
wings (not included in shipment - SVSi part number N9101). See Figure 2-1
.
2. Place the unit against the solid surface to which you want it mounted.
3. Using standard hardware, attach the unit through each of the slots of the newly-attached
mounting wings.
4. Connect the appropriate cables necessary for your application. Refer to the sections
Connecting Decoders to the Network
on page 23 and Connecting Encoders to the Network
and Configuring Stream Settings on page 25 for more information on these connections.
Figure 2-1. Installing Mounting Wings
Page 18 N2000 Series User Manual www.svsiav.com
Chapter 2. Installation Rack Mounting Options
Rack Mounting Options
N2000 Series Stand-Alone Units
A Rack Shelf (SVSi part number N9102) accommodates up to two stand-alone N-Series
Encoders or Decoders, side by side (mix and match).
Figure 2-2. Rack Mounting Stand-Alone Units
N2000 Series Cards
A Card Cage (SVSi part number N9206) accommodates up to six N-Series Encoder/Decoder
cards (mix and match). The 12V power supply of the N9206 is the primary power source for the
installed cards. If the 12V power supply fails or is unplugged, the cards will power down, detect
PoE (if provided by switch) and restart normally using PoE. This usually results in a power loss of
about one to two seconds. The unit then reboots (which takes another one to two minutes).
To rack mount N2000 Series cards into the N9206 Card Cage, follow these steps:
1. Gently slide the card into cage slot. Make sure the card is properly aligned with guides. The
card’s front LED indicators should align with holes in the cage’s faceplate. See Figure 2-3
.
Figure 2-3. Rack Mounting Cards
Page 19 N2000 Series User Manual www.svsiav.com
Chapter 2. Installation Rack Mounting Options
2. Align the thumb screw on back plate before seating card into cage.
3. Firmly seat the card and tighten the thumb screw by hand to secure card placement.
4. Use one of the six Phoenix connector cables (included in shipment with the Card Cage) to
connect the card’s 12VDC input Phoenix connector to one of the cage’s six 12VDC outputs.
5. Repeat these steps until all cards are properly installed. See Figure 2-4
.
Figure 2-4. Fully-Populated Card Cage
6. For proper airflow, cover any unused card slots with faceplate blanks. Blanks are sold
separately (SVSi part number N9210).
7. Make sure the Card Cage’s power cord is plugged in for proper cooling.
Caution: Keep the Card Cage’s power cord plugged in at all times so that the internal fans
are always running. Not doing so could void the warranty of the cage and all installed cards.
Fans are not powered while in backup PoE power mode. Please remedy power losses
immediately to avoid potential overheating hazards.
Note: Mounting accessories are sold separately and are compatible with most N-Series
devices. Contact an SVSi sales representative or visit our website for details.

Chapter 2. Installation Step-by-Step Installation Instructions
STEP-BY-STEP INSTALLATION INSTRUCTIONS
This section provides step-by-step guidance for installing and configuring SVSi equipment on your network.
The steps provided here assume the following to be true:
1. There are PoE switches operational on the network.
SVSi equipment can operate on many different brands of networking equipment. The network
itself needs to meet certain requirements to be able to support an SVSi deployment. These
instructions assume that you have purchased and installed a pre-configured switch from SVSi
or that your existing equipment meets the following physical and protocol requirements:
Layer 3, also known as “multi-layer”
Gigabit Ethernet
IGMP Snooping
IGMP Snooping Querier (which only needs to be enabled on a single switch within the net-
work)
2. Deployment considerations have been made for the addition of high-speed video.
Our Networked AV solutions provide unsurpassed video and audio quality at bandwidths
appropriate to any network segment or link. Matrix switches as large as 1200x800 have been
constructed on a house network using SVSi’s equipment. Alternatively, many customers
choose to deploy on physically separate networks in order to use low-cost network appliances
but keep video traffic separate from data and voice.
3. You loaded N-Able onto the computer you are using to configure the equipment.
From your host computer, click this link to download N-Able (SVSi’s free setup utility software)
for PC or Mac: http://svsiav.com/support/resources/software
. This software is designed to set
up and control the equipment during initial deployment, however, it is not always the best
solution for production-type or primary user control. Refer to Control Options
on page 33 for
details on the available control options.
Note: To proceed with this installation, the switches must already be successfully connected
to your network. If needed, refer to your product’s documentation for installation instructions.
