GoStream Series User Guide

Operating Temperature

The operating ambient temperature of a rack environment may be greater than room ambient if installed in a closed or multiunit 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 GoStream series 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.

Note to CATV Installer: Pay special attention to Section 820-40 of the NEC that provides guidelines

GoStream Series User Guide

Installing additional software

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 system may fail.

You may load additional software on the system; however, ViewCast does not support this additional software. You also need to ensure the primary drive is not full or the system will fail. In the event of a problem, you may need to perform a Factory Restore, which returns the system 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 system to the software load that came with the system. Perform a Factory Restore if the system 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 system 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.
