An Economical Solution for Power Supply Redundancy for Single Inlet Network Devices

Given the increasing importance of internet access in a wide range of different mission critical applications, power supply redundancy solutions are quickly becoming an increasingly common element in remote network equipment racks. Power supply redundancy is a vital element in any network application that requires 24 hour accessibility, in that it allows network equipment to quickly switchover to a secondary power supply in the event that the primary power supply fails. In spite of the growing importance of power fallback and redundancy capabilities, there’s one simple factor that often stands in the way of implementing a power redundancy solution: the cost of replacing existing single power inlet network devices.

If currently you’re putting off the task of adding power supply redundancy to your network equipment rack because of the cost of replacing single inlet devices, you might want to investigate the economical, efficient power redundancy capabilities that can be provided by an automatic transfer switch. An automatic transfer switch allows you implement a power redundancy strategy, without the need to replace existing single inlet network devices with expensive new dual inlet devices.

Installation and operation of an automatic transfer switch are incredibly simple and generally require no reconfiguration of existing devices. When installing an automatic transfer switch, power supply cables from existing single inlet devices are first connected to the automatic transfer switch, and next, power supply cables from the automatic transfer switch are then connected to your primary and secondary power supplies … and that completes installation. Once installed, the automatic transfer switch will then monitor the flow of power from it’s power source, and then quickly switch over to the backup power source if the transfer switch determines that the power source is unstable. In some cases, automatic transfer switch units also include the ability to switch back to the primary power source when the switch determines that the primary source has stabilized or resumed proper operation.

In most cases, the switchover from primary power source to backup power source is so fast, that it is generally transparent to end users. A high quality automatic transfer switch can often support switchover times as rapid as eight to twelve microseconds. When selecting an automatic transfer switch, it’s also important to choose a product that supports out-of-phase switching in order to further guarantee that switchover times are as fast and undetectable as possible.

Power supply redundancy and power fallback capabilities are an important element in any network application that needs to provide continuous access to network services 24 hours a day and seven days a week. A carefully thought out power supply redundancy strategy will help to ensure that vital network functions are always available to users, even when a primary power supply at a network equipment site hiccups and threatens to take down vital network elements. An automatic transfer switch provides an ideal solution for any network manager who needs to implement a power redundancy solution for vital network devices, but is prevented from doing so by budgetary concerns and the high cost of replacing existing single power inlet network devices.
