The Transfer Switch – Effective Power Redundancy without all the Costs and Hassles

When power to a critical network device suddenly fails or becomes unstable, the resulting network outage can often create a wave of pain that’s quickly felt throughout your entire organization. Network communication is a vital part of any modern business, and most businesses can’t afford to have a relatively minor inconvenience, such as a power failure, interfere with the ability of their employees and customers to access important network resources and communication capabilities. This is exactly why so many businesses are updating their network infrastructure to include power fallback and power redundancy capabilities.

One of the most common obstacles that’s often encountered when implementing a power redundancy strategy, is the presence of many older, single-power-inlet devices in the network infrastructure. Although the easiest solution to this dilemma would be to simply replace these older, single-power-inlet devices with sparkling new, dual-power-inlet devices, unfortunately, these days many IT departments are faced with tightening budgets and just don’t have the cash available to go out and drop tens of thousands of dollars on new dual-inlet devices (and that’s not even considering the man-hours that would be spent configuring these new devices for compatibility with your existing application.) In cases like this, a transfer switch unit can provide network administrators with an economical alternative to purchasing new dual inlet devices, while still permitting an effective power redundancy solution without the cost or hassles of replacing existing single-power-inlet devices.

Simply speaking, a transfer switch provides power fallback and redundancy capabilities to existing single-power-inlet devices by allowing those devices to be connected to both a primary power source and a back up power source; effectively eliminating the need for new dual-inlet devices. Installation of a transfer switch is incredibly simple; first, existing single-power-inlet devices are connected to power outlets on the transfer switch, and then power supply cables from the transfer switch are connected to your primary power supply and backup power supply. Once installed, the transfer switch will continually monitor the active power supply, and then automatically switch over to the secondary power supply if the active power supply fails or appears to destabilize.

When power fallback switching occurs, a high quality transfer switch can usually switch over to the back up power supply in about eight to twelve microseconds, providing switchover times that are so brief, that most users and devices will not be able to tell that the switchover has taken place. A well designed transfer switch will also usually support the ability to switch back to the primary power supply if it is determined that the primary power supply has stabilized again.

These capabilities can prove a vital help for budget-plagued network administrators who desperately need to implement a power fallback and redundancy solution, without the huge costs of replacing existing single-power-inlet devices, or the tremendous hassle of reconfiguring new dual-power-inlet devices for compatible with your network application.

With a transfer switch, there’s no need to put off the implementation of an effective power redundancy solution, and risk network disasters that are caused by simple power supply failure. A transfer switch can provide a sound, working power redundancy solution without the expense of replacing older network equipment, or the problems associated with configuring new devices to work with your existing application.
