The following is an example of an invalid Class C addressing scheme:

Device

IP Address

QGE 100 viewing computer

208.132.180.41

 

 

QGE 100 encoder 1

192.157.180.42

QGE 100 encoder 2

209.100.123.43

NOTE: The above addresses are invalid because the network identifier for each address is not the same even though each IP address is unique.

You can perform a test from your computer to check that a device at a particular address is responding correctly or to determine its address (see “Pinging for the IP Address”).

Subnet Mask

The subnet mask is another 32-bit binary number that is used to “mask” certain bits of the IP address. This provides a method of extending the number of network options for a given IP address. It works by allowing part of the host identifier to be used as a subnet identifier.

It is important that you set the correct value for the subnet mask. The basic values depend on the class of IP address being used.

Class Name

Subnet Mask

Class A

255.0.0.0

Class B

255.255.0.0

 

 

Class C

255.255.255.0

See “Subnetting, a Primer” on page 51 for more information.

Pinging for the IP Address

To access the QGE 100 via the Ethernet port, you need the encoder IP address. If the address has been changed to an address comprised of words and characters, the actual numeric IP address can be determined using the Ping utility. If the address has not been changed, the factory-specified default is 192.168.254.254.

Ping can also be used to test the Ethernet link to the QGE 100.

Ping to determine the Extron IP address

The Microsoft Ping utility is available at the command prompt. Ping tests the Ethernet interface between the computer and the encoder. It can also be used to determine the actual numeric IP address from an alias and to determine the web address.

Ping the QGE as follows:

1.From the Windows Start menu, select Run... . The Run window opens.

2.In the Open text field, enter command.

3.Click OK. A command window opens.

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.
