IP Addressing

What is an IP Address?

A full explanation of IP addressing is beyond the scope of this user guide. However, the following details provide enough information to get started.

An IP address is a 32-bit binary number that is used to identify each device on an Ethernet network. This number is usually represented by four decimal numbers (each in the range or 0 to 255) separated by dots, such as 198.123.34.240. This is called “dotted decimal notation.”

An IP address is divided into two parts:

•Network identifier

•Host identifier

Each address on a given network must have the same network identifier value but have a unique host identifier. As a result, there are different classes of addresses the define the range of valid addresses and which parts of the address are used for the network and host identifiers.

The most common IP address classes are:

Class Name

Valid Address Range

Identifier Arrangement

 

 

 

Class A

0.0.0.1 to 127.255.255.254

NNN.HHH.HHH.HHH

 

 

 

Class B

128.0.0.1 to 191.255.255.254

NNN.NNN.HHH.HHH

Class C

192.0.0.1 to 223.255.255.254

NNN.NNN.NNN.HHH

NNNrefers to the network identifier and HHH refers to the host identifier.

Choosing IP Addresses

If the computer and QGE 100 are directly connected or connected via their own independent network, follow the guidelines below for choosing the IP addresses.

However, if you intend to connect your computer and QGE 100 to an existing network, notify the network administrator and ask them to allocate suitable IP addresses.

On an independent network, it is generally recommended that you use the Class C format (from 192.0.0.1 to 223.255.255.254).

There are two rules for choosing IP addresses:

•Network identifier must be the same for each IP address

•Host identifier must be unique for each address.

Applying these rules to Class C addresses, the first three decimal values of your IP address must all be the same, while the last value is used to uniquely identify each device.

The following is an example of a valid Class C addressing scheme:

Device

IP Address

QGE 100 viewing computer

208.132.180.41

QGE 100 encoder 1

208.132.180.42

 

 

QGE 100 encoder 2

208.132.180.43

NOTE: The host identifiers (41, 42, and 43 in the above example) do not need to be

sequential or in any particular order. However, it is recommended that you

group the numbers for simplicity.

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.
