The Transfer Switch – An Economical Solution for Effective Power Redundancy

When a vital network element loses power and shuts down, the resulting outage can disrupt access to important network services or at worse, bring your entire network to its knees. This is a pretty familiar problem to most network administrators, and in most cases, the most obvious way to prevent this type of situation is to make certain that all of your vital network devices have access to a back-up power source. Although a power redundancy solution is easy to implement when the network device in question includes dual power inlets and built in power fallback capabilities, it can be a different matter if that vital network element only includes one power inlet.

The cost of replacing existing single power inlet network elements can be both a tremendous burden on your IT budget, and an incredible hassle to boot. A brand-new dual power inlet network device might offer the ideal solution, but the cost of new dual inlet devices can be astronomical, and the hassle of reconfiguring your existing network for compatibility with new dual inlet devices can also be an incredible burden to bear.

If high equipment costs and potential compatibility problems are the only thing standing between you and an effective power redundancy solution, an economical transfer switch might provide the best solution. A transfer switch allows you to implement an effective power redundancy solution without the need to replace existing single power inlet devices or reconfigure you infrastructure for compatibility with new dual-inlet devices. When properly applied, a transfer switch saves both money and reconfiguration hassles, yet still provides your network application with a reliable, effective power redundancy solution.

Installation and operation of a transfer switch is deceptively simple. First, the transfer switch is connected to both your primary power supply and your secondary, back-up power supply. Next, existing single power inlet devices are connected to the transfer switch. Typically, each transfer switch can support up to eight single power inlet devices, and in the event that the primary power supply fails or becomes unstable, the transfer switch can almost instantly begin to draw power from your secondary power source. Switchover time is incredibly rapid. A good transfer switch should be able to provide switching times as brief as eight to twelve microseconds; fast enough that the switchover is generally undetectable by both users and connected devices.

In today’s network-centric business environment, it’s absolutely mandatory that network services are always up and running, and available for use when they’re needed. When the network stops, often the whole business either comes to a halt or slows to a crawl. As business becomes more reliant on computer networks and data services, the importance of minimizing network downtime has become a top concern for almost every network administrator. Although a power redundancy solution can help businesses and organizations to avoid one of the most common pitfalls that interrupt network service, simple things, such as existing single power inlet devices can often make a power redundancy a difficult thing to actually implement. If your power redundancy project has been stopped in its tracks by the high cost of replacing existing single inlet devices, an economical transfer switch can often provide a reliable, effective solution, without the need to burn your budget on new dual power inlet devices.
