Preface
This guide describes the installation and startup instructions for the
Narrowcast Services Gateway family, including the NSG 9116, 9112 and
9108. The NSG is a highly integrated digital video and data gateway
between on-demand content servers and their subscribers. Designed as
a 1-RU chassis, the NSG family performs PID filtering, multiplexing,
scrambling, QAM modulation, and RF upconversion for either sixteen,
twelve or eight transport streams simultaneously. It can supply video and
other on-demand multimedia services to large numbers of subscribers.
The NSG accepts digital MPEG input through a Gigabit Ethernet (GbE)
port. The NSG directs multimedia to the different QAMs and up-
converters to create the outgoing transport streams as QAM-RF output
signals.
Note: This guide uses the term NSG to refer to the NSG 9116, 9112
and 9108.

Features and Specifications
Introduction
NSG 9100
Harmonic's NSG 9100 product line includes the NSG 9116, 9112 and
9108. The NSG provides digital video remultiplexing, scrambling, QAM
modulation, and RF upconversion for video on demand networks. The
NSG accepts digital MPEG input through 2 x GbE ports configured to
work as redundant GbE channels or as independent channels that
simultaneously receive different GbE feeds. The NSG delivers up to
sixteen transport streams through RF output ports implementing dual
upconverter technology.
The following table provides a general description of the NSG 9100
product line:

2Introduction CHAPTER 1
Note: The NSG comes with either an AC power supply or –48 VDC
power supply. All types of NSGs are intended to be installed in
restricted access locations.
Management Interfaces
Harmonic offers several methods for configuring NSG devices and
monitoring their status. All management interfaces listed below connect
to the NSG over LAN, via its ETH1 Ethernet port.
Caution: Harmonic strongly recommends using an Ethernet network
that is isolated from any other networks or subnets at your site for
management of the NSGs.It ensures adequate security, and prevents
possible disturbances to the normal operation of NSG devices due to
uncontrolled network activity.

3Features and Specifications Introduction
The table below lists the available management interfaces according to
the management purpose for which they are designed:
Purpose Recommended Tool
Preliminary
configuration and
monitoring of a
single NSG device
Control Panel
The NSG control panel is comprised of a display area and
key pad located on the front panel of the NSG. The control
panel is active once the NSG boots up and provides
means for preliminary configuration of a single NSG
device. It also allows you to monitor the NSG's status, view
its alarms (if present), and troubleshoot them. For details
on accessing the web client, please see the NSG Web
Client..
Configuration and
monitoring of a
single NSG device
The NSG web client is an on-board web-based user
interface, that is an integral part of the NSG firmware. The
web client is accessible through Microsoft Internet
Explorer, and provides means for configuring a single
NSG device. It also allows the user to monitor the NSG's
status, view its alarms (if present), and troubleshoot them.
For details on accessing the web client, see Chapter 2,
“Connecting Power,” .

4Introduction CHAPTER 1
Note: The MCT database is not automatically updated when an NSG is
configured using NMX or the web client. To update the MCT database,
select the NSG and execute the following command from the MCT
Actions menu: Actions > Synchronize > Get from Target.
GbE Channel Redundancy
The NSG family supports GbE redundancy to provide the network with
fault-tolerant design. The objective of the redundant channel is to
eliminate or diminish any service interruptions when an active GbE
Configuration of

devices
MCT (Mass Configuration Tool).
The MCT is a spreadsheet-oriented system designed to
configure multiple NSGs simultaneously. MCT is
recommended for large-scale NSG deployments. Besides
simultaneous configuration of large number of NSG
devices, it also allows users to perform firmware upgrade
for multiple NSGs. MCT is sold separately - please contact
Harmonic Customer Support for more details.
Note: MCT is not automatically updated when an NSG is
configured through the web client. Using the web client
for configuring individual NSGs in an MCT-based site is
not recommended. If the web client is used, care should
be taken to update MCT with the changed configuration.
For details on synchronizing MCT with NSG devices,
please refer to the MCT online help.
Status and Alarm
Monitoring of
multiple NSG
devices
Harmonic NMX / 3rd party SNMP monitoring.
NMX (Harmonic's Digital Service Manager) may be used
for monitoring general status and alarms of multiple NSG
devices. A single NMX manager may be used to monitor
several hundreds NSG devices, located in several different
sites.
In addition, NSG may report its status and alarms via
standard SNMP. Any standard-based SNMP monitoring
system may be used for monitoring the status of multiple
NSG devices. This includes off-the-shelf systems such as
HP OpenView, or custom-made systems. For further
details on implementing SNMP monitoring for NSG
devices, please contact Harmonic Customer Support.

channel fails. NSGs with the redundancy feature do not have a primary
and secondary channel but rather have two symmetrical GbE channels.
Therefore, when a redundant channel is activated it will continue to
operate and will not revert back to the previously active channel when
that channel recovers.
Redundancy for both GbE1 and GbE2 is activated by one of two NSG
alarms:
■Chapter 3, “GbE X Link down,”
■Chapter 3, “GbE X SFP not mounted,”
Note: Automatic GbE channel redundancy is unavailable in Switching
mode. In this mode the ports are configured to work independently and
to receive different GbE feeds.
Note: Automatic GbE channel redundancy is unavailable when using
copper SFP. The redundant channel is activated only when the alarm
SFP not mounted appears. The SFP does not trigger the GbE link down
alarm.
NSG Backup Capability
The NSG includes a Non Volatile RAM (NVRAM) that is also powered by a
lithium battery. The NVRAM allows configuration backup and maintains
the NSG time.
Caution: Risk of explosion if battery is replaced by an incorrect
type. Dispose of used batteries according to the instructions.
