Power Fallback Always Seems Like a Good Idea After a Power Outage Interferes with Network Communication

When a power outage at a remote equipment rack site takes down your network, suddenly the importance of an effective power redundancy solution becomes all too clear. Network outages are always costly; whether you’re talking about lost productivity, lost business opportunities or just the hassle of being without valuable network communication capabilities when you need them the most, a network outage always makes the cost of a power redundancy solution or power fallback strategy seem well worth whatever funds it might cost to put one together.

Unfortunately, in these days of tightening IT budgets, network administrators often decide to go without a workable power redundancy solution, merely for the sake of cutting costs. Typically, the one factor that stands in the way of implementing an effective power redundancy solution is the cost of replacing existing single-power-inlet network devices with expensive, new, fallback-friendly dual-power-inlet devices. But it doesn’t have to be that way; a simple, economical transfer switch can provide your network the same protection against power outages without the need to toss perfectly good single-power-inlet devices and replace them with dual-power-inlet devices.

A transfer switch helps to minimize network downtime without the cost or reconfiguration hassles of replacing functional single-power-inlet devices by providing those single-inlet devices with the same power fallback capabilities that are found on new dual-inlet devices. Installation and operation of a transfer switch is deceptively simple. The transfer switch is connected to both your primary power supply and secondary, back-up power supply, and your network devices are then connected to the transfer switch. In the event that your primary power supply fails or becomes unstable, the transfer switch will almost immediately begin drawing power from the secondary power supply. A high-quality transfer switch can often provide switchover times as brief as eight to twelve microseconds; fast enough that the power transfer is generally transparent to both users and equipment alike.

In addition to providing the ability to switch over to your secondary power supply, a well-designed transfer switch will often support the ability to resume drawing power from the primary power source if the transfer switch determines that the primary power source has resumed operation or stabilized. Transfer switch products are typically available for both 120 VAC and 240 VAC operation to fit the needs of a wide variety of different power fallback applications.

An effective power redundancy solution is a vital element for any application that includes network communication with off-site data centers and remote equipment racks. But too often, the importance of a power redundancy solution doesn’t become clear until a power outage takes out a vital network element at a remote site and then impacts or interrupts network communication on a larger scale. As valuable as a power redundancy solution is though, a power fallback solution doesn’t have to be an expensive proposition that requires the replacement of half of the devices in your remote equipment rack … that is, not if your power fallback or power redundancy plan relies on the efficient power transfer abilities provided by a simple, economical transfer switch.
