Mounting the QGE 100 Encoder

The QGE 100 encoder can be placed on a tabletop or mounted in a rack.

NOTE: Always use the special QGE 100 rack mounting kit (part number 70-755-01),

available separately, to secure the unit to the rack. Mounting instructions are included with the kit.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the QGE 100 encoder into a rack:

•Elevated operating ambient temperature — If the equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

•Reduced air flow — Install the equipment in the rack so that the amount of air flow required for safe operation of the equipment is not compromised.

•Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not create a hazardous condition.

•Circuit overloading — When connecting the equipment to the supply circuit, consider the connection of the equipment to the supply circuit and the effect that circuit overloading might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings when addressing this concern.

•Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Other Rack Mounting Requirements

In addition to the UL guidelines, observe the following when mounting the encoder:

CAUTION: Do not stand other units directly on top of the QGE when it is

rack mounted, because this can place excessive strain on the mounting brackets.

Ventilation

Ensure that sufficient airflow is provided to satisfy the ventilation requirements of all items of equipment installed in the rack.

A ventilation gap of at least 1.7 inches (44 mm) must be left above and below the unit, as well as between the unit and adjacent surfaces or equipment.

Power supply

•If using a power strip (either hard-wired or plug and socket), ensure that the current rating of both the power strip and the power supply is sufficient for all equipment within the rack.

•Always ensure that the power supply is of the correct voltage and frequency for all equipment within the rack and that it is properly grounded.

QGE 100 specifications

The Extron QGE 100 is a high-performance network switch engineered specifically for AV system integration. With its advanced capabilities, this device plays a crucial role in managing AV data traffic, ensuring reliable performance and efficiency in various settings such as corporate environments, educational institutions, and healthcare facilities.

One of the key features of the QGE 100 is its support for Power over Ethernet (PoE). This allows the switch to deliver both data and power to connected devices over a single Ethernet cable, simplifying installations and reducing the need for additional power sources. This is particularly beneficial for devices like IP cameras, wireless access points, and AV devices in scenarios where accessibility to power outlets may be limited.

The QGE 100 also provides a robust Layer 2 switching functionality, which is essential for managing data flow within the network. Its capability to handle multiple VLANs ensures that AV traffic can be segregated effectively, thus improving network performance and security. The switch features IGMP Snooping, a protocol that optimizes multicast traffic management, ensuring that video streams reach the intended recipients without unnecessary bandwidth consumption.

In terms of connectivity, the Extron QGE 100 is equipped with multiple Gigabit Ethernet ports, facilitating high-speed data transmission for AV content. The switch's user-friendly management interface allows for straightforward configuration, monitoring, and troubleshooting, streamlining operations across AV environments. Additionally, it supports link aggregation, enhancing bandwidth and redundancy when connecting multiple devices.

The QGE 100 is also designed with reliability in mind, featuring a fanless operation that minimizes noise and ensures a long lifespan. Its compact form factor allows for easy rack mounting in equipment racks, maintaining a clean and organized setup.

Another vital characteristic of the QGE 100 is its compatibility with Extron's comprehensive suite of AV control and management products. This integration capability provides users with a cohesive solution for managing their AV systems, further enhancing the overall user experience.

In conclusion, the Extron QGE 100 network switch is an essential tool for any AV system requiring efficient connectivity, power delivery, and data management. Its sophisticated features and technologies make it a valuable asset in modern AV installations, ensuring robust performance and ease of use.
