Rack mount safety instructions
Operating Temperature
The operating ambient temperature of a rack environment may
be greater than room ambient if installed in a closed or multi-unit
rack assembly. Therefore, you should install the equipment in an
environment compatible with the maximum ambient
temperature of 40° C.
Reduced Air Flow
You must not compromise the airflow required for safe
equipment operation when you install the equipment in a rack.
Mechanical Loading
Mounting of the equipment in the rack should be such that you
do not cause a hazard due to uneven mechanical loading.
Circuit Overloading
Consider the connection of the equipment to the supply circuit
and the effect that the overloading of the circuits might have on
current protection and supply wiring. You must also consider and
use the equipment nameplate ratings when you address this
concern.
Reliable Grounding
You must maintain reliable earth grounding of rack-mounted
equipment. Pay particular attention to supply connections other
than direct connections to the branch circuit (such as using power
strips).

FCC notice
WARNING! You must connect this device and peripherals using shielded cables to comply with FCC
radio emission limits.
WARNING! Modifications to this device not approved by ViewCast Corporation could void the FCC-
granted authority for you to operate the device.
WARNING! The Niagara 4100 complies with the limits for a Class A digital device pursuant to Part 15
of the FCC Rules. These limits provide reasonable protection against harmful interference when you
operate the equipment in a commercial environment. This equipment generates, uses, and may
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area will likely cause harmful interference. In this case you must correct the interference
at your own expense.
To CATV Installer: Pay special attention to Section 820-40 of the NEC that provides guidelines for
proper grounding. It particularly specifies that you must connect the cable ground to the grounding
system of the building as close to the point of cable entry as practical.
WARNING! Equipment installation must comply with local and national electrical codes.

Installing additional software
The Niagara systems run an embedded version of the Microsoft Windows 7 operating system (OS),
which is a sub-set of the normal retail version. The Microsoft License agreement limits the use of the
system to what the machine is designed to do.
The Microsoft Update process is turned off by default to prevent interruptions during live streaming
events. It is also not advised to use a Windows 7 installation CD to add features to the system or the
appliance may fail.
You may load additional software on the appliance; however, ViewCast does not support this additional
software. You also need to ensure the primary drive is not full or the appliance will fail. In the event of a
problem, you may need to perform a Factory Restore, which returns the appliance to the original
software load. You may save the current encoder profiles and reload them when the Factory Restore is
complete.
You can perform a Factory Restore at any time. This process returns the appliance to the software load
that came with the appliance. Perform a Factory Restore if the appliance becomes unstable due to
installed applications, viruses, etc. Please refer to the user guide for instructions.
ViewCast Support can provide assistance should the system fail to start. In most cases, you can restore a
system to operation without returning it to ViewCast. There is a fee in the event a user returns a system
due to applications the user installed or if the appliance failed because the primary partition (drive C) is
full.
Connecting to the Internet
Never connect a Niagara system directly to the Internet. ViewCast recommends taking precautions
against unwanted access such as installing Niagara systems behind a router or firewall. The speed of the
router or switch should match or exceed the speed of the system’s network card. See your network
administrator for recommendations.

Warnings
Only trained and qualified personnel should install, replace, or service this equipment.
Do not attempt to open the case of the system. If you do, you incur a high risk of electrical shock that
may cause damage to the system or personal physical injury or death to you and/or others. No user-
serviceable parts exist inside the system. If you open the system case or make unauthorized changes to
the case, you void the warranty.
Install the system away from any heat sources. This remains vital to the safety of the product users. Do
not install the system near any heat sources such as:
Radiators
Heat registers
Stoves
Other heat-producing equipment
WARNING! Installing the system near heat sources could result in personal injury or death.
Never insert objects of any kind into the system through any system openings, as the objects may
touch dangerous voltage points, short out parts, and result in a risk of fire or electrical shock.
Do not stack the system atop or below other electronic devices as this can cause heat build-up and
vibration of the system. These conditions can damage the system thereby voiding the limited warranty.
You may stack multiple Niagara 4100 units as these systems accommodate stacking.
Do not install the system in any area where the temperature is less than 5°C or more than 40°C. Transfer
from temperature extremes may cause condensation. Let the system remain unplugged at room
temperature for at least 45 minutes before connecting it.
Use an outlet with surge suppression or ground fault protection when using the system. Unplug the
power cord from the wall outlet, disconnect the network connection, and disconnect the lines between
the system and the video source for added protection:
During a lightning storm
During dangerous weather conditions
When the encoder remains unattended or unused for long periods
Reduce the risk of fire or electric shock. Do not expose the system to any rain or moisture. Exposing the
system to rain or other types of moisture could result in system damages. Do not place any liquids on or
near the system. If you place liquids in any form on or near the system, do so at your own risk, for you
incur a high risk of electrical shock that could occur and cause damage to the system.
WARNING! Exposing the system to rain or other types of moisture could result in physical injury or
death. Any liquids on or near the system may result in electrical shock and personal injury or death.

Refer all servicing to authorized service personnel. You must have authorized personnel only service any
damaged system. Relevant damage may occur with but is not limited to the following:
An unplugged or damaged power supply cord
Spilled liquid on the system
Fallen objects in or on the system
Appliance exposure to rain or other moisture or liquid
Failure to perform as described in the User Guide
A dropped system
ViewCast assumes no liability or responsibility for any damaged system that clients continue using.
Use only attachments, accessories, or equipment specified by the manufacturer with the system. Using
accessories or attachments not recommended by the encoder manufacturer voids the Limited
Warranty.
WARNING! When using 4-pin XLR to cigarette car plug cables, do not disconnect the car battery
adaptor or turn off the car engine before you turn off the player. Doing so may damage the player.
Do not attempt to service the system yourself. If you open or remove covers, you may be exposed to
dangerous voltage. Such action voids the Limited Warranty. Refer all servicing issues to authorized
service personnel only.
The plug-socket combination that serves as the main disconnecting device must be accessible at all
times.
Protect the power cord from anyone walking on it and being strained or pinched particularly at plugs,
electrical receptacles, and the point where the power cord exits the system.
Do not use adapter plugs or remove the grounding prong from the power cable.
Use only the type of power source indicated on the marking label on the back panel of the unit to
operate the system. Unplug the system power cord by gripping the plug and removing it from the power
source. Do not pull the cord to remove the power source from the system.
Do not plug the system into a wall outlet that contains an overload of electrical cords or power
strips/extension cords. This type of overload may result in fire or electrical shock risks.
Always handle the system carefully. Always avoid excessive shock and vibration to the system. Excessive
shock or vibration can damage the system.
WARNING! Excessive shock or vibration to the system may result in electrical shock and personal injury
or death.
