The Remote Power Switch

A KVM Switch allows the connection of a Keyboard, VDU (Video Display Unit) and mouse to multiple computers. The user determines which certainly one of quite a lot of computers they wish to take control of. It’s a hardware device that enables collection of individual computers or servers by means of a simple control system using a simple dial or button.

Some KVM Switches can have the added capability to regulate associated USB devices and even speakers. Products utilising Category 5 twisted pair cable can be utilized to manage equipment at distances up to 300 metres, often using some form of manufacturers proprietary protocols.

A later innovation has been KVM over IP, where the KVM Switch conveys the control information and captured keyboard, video and mouse signals via an IP over Ethernet link to a remote application. This greatly increases the range and scope of control over LAN, WAN and Serial Point-to-Point links. The common method is to attach via a web browser using some type of proprietary software, but security is an obvious issued. This is handled by implementing SSL (Secure Sockets Layer) with 128-bit encryption.

Organisations that have plenty of dedicated servers may well opt to use KVM Switches to enable the servers to be monitored and controlled individually from a single device. Administrators and operators can switch between physical server devices at the flick of a switch or push of a button.

Keyboard, Video and Mouse Switches are available in various formats including Desktop and Rackmounted models. These products come as Direct Connect systems, Networked systems and those that are controlled from a dedicated console. Along with the KVM Switches most major manufacturers will normally have an in depth range of accessories comparable to interface modules, cable adapters and cable kits.

For some time now, VGA based switches have probably been the preferred format, but HDMI (High-Definition Multimedia Interface) and DVI (Digital Visual Interface) are quickly becoming efficient digital alternatives to VGA.

DVI is a typical digital standard that’s popular for PC connections to display units and HDMI is an uncompressed digital standard for audio and video signals. It is ready to pass both the video and audio down a single cable between such devices as DVD Players, Set-Top boxes and a digital television.

Control connections on KVM switches are commonly PS/2, which was the common standard for mouse and keyboard connections for many years, and USB which is simpler and more flexible. Plenty of Switches have the choice of either. The user just has to remember to buy the appropriate cable types, unless they’re supplied with the switch.

KVM Switches are manufactured by numerous manufacturers. If you’re looking to buy then I like to recommend the manufacturer that has an excellent reputation for providing an in depth range of accessories and a very good range of switches themselves.
