New Article Offers Insight into the Advances in Network Switches
A free downloadable article is available on the Advances in Network Switches. This article brings to the forefront the latest innovations in the design of copper and fiber optic network backup switches.
The article features clear-cut tables that show at a glance the basic determinants of copper and fiber optic network switches. The article covers the topic of flexibility in switch controls with easy to follow explanations and product photos. Control methods include pushbutton, keylock, RS232 serial control, contact closure, IP addressable, graphical user interface (GUI), code-operated, and automatic switching.
Redundancy in network switches is explained with two examples, redundant backup and redundant remote port and power supplies. An example of a normal/redundant fallback switch is used as the first example and a special switch that was designed with two remote ports and two power supply ports as the other.
Methods of handling data transmission and power loss are also discussed. This very important topic covers switches that continue to pass data in the event of a power loss; switches that will not pass data through the unit during a power loss, and switch position memory.
Methods of switch monitoring are detailed. These include simple front-panel monitoring, RS232 remote port, Graphical User Interface, Telnet, voltage signaling and a supervisory remote port and Telnet.
There is a lot to know about copper and fiber optic network backup switches. Today’s network switches can be designed to fit anywhere: desktop, computer room rack, process control system, nuclear power plant and other rough environments. They can be built with the ruggedness necessary to function in areas subject to noise, vibrations and extreme temperatures. Security issues are addressed with passwords, passwords with limited privileges, secure offline positions, key-locks, and the ability to lockout the front panel controls remotely.
