The Power Transfer Switch – An Easy, Economical Way to Implement Power Fallback Capabilities

Often, network administrators are left with two choices when adding power redundancy and power fallback capabilities to an existing network equipment application; the expensive way and the easy way. The expensive way requires replacing every single existing single-power-inlet network device in the rack with a new dual-power-inlet device, and the easy way only requires the installation of an inexpensive, easy-to-operate power transfer switch in order to provide power fallback and redundancy capabilities to existing single-power-inlet devices.

Given the importance of power fallback and power redundancy in any heavily used network application, many network administrators and engineers are faced with challenge of adapting their existing network infrastructure to ensure that even when the primary power supply fails or becomes unstable, network equipment will still be able to draw power from a secondary power source in order to provide uninterrupted operation. In most cases, a power transfer switch provides the most simple and economical means to provide single-power-inlet network elements with the power fallback and power redundancy capabilities that are vital to any critical, modern network application. This is especially true in cases where budgetary constraints rule out the purchase of all new dual-power-inlet devices to replace single-inlet devices, yet the administrators still need to maximize network up-time and eliminate network outages caused by power supply instability.

In addition to economy and convenience, a power transfer switch also provides other advantages, such as enabling network applications to continue using existing devices without the need to reconfigure large chunks of their network infrastructure, as is often the case when single-power-inlet routers, servers and other elements are replaced with dual inlet devices. Since a power transfer switch allows you to implement an effective power redundancy solution without changing out existing network elements, this also generally means that network operating and maintenance tasks will also remain unchanged, reducing the need to retrain tech support personnel and network users.

A power transfer switch can also prove to be very helpful in cases where a new element is being added to an existing network application that already includes power redundancy and fallback capabilities, yet the new network element just isn’t available in a dual-power-inlet configuration. Rather than requiring network engineers and administrators to choose network elements based on the presence of a dual-power-inlet configuration, a power transfer switch allows engineers to select new network elements based on more important factors such as operating features and reliability, and then leave the power redundancy part of the job to the power transfer switch.

If you’re faced with the sometimes difficult task of adding a power redundancy/fallback solution to an existing network application, or even if you’d just like to add a particular single-power-inlet network device to a network application that already supports power fallback, a power transfer switch can often provide a simple, economical and effective means for accomplishing your goals. A power transfer switch can both eliminate the need to replace existing single-inlet devices, and also enable you to add single-inlet devices to your network application without compromising power fallback and power redundancy capabilities.
