An essential component to avoid agonizing trips to reset routers

Cisco Professionals eTips and Tricks

Power interruptions from storms, brownouts, and other glitches lasting only a few seconds or less can wreak havoc on a network. Even the shortest outage can potentially stop important applications and cause an administrator to have to manually reset a router. This is why it's so important to have an uninterruptible power supply (UPS). Unlike a backup generator or other emergency power system, a UPS is designed to kick in immediately, keeping the power supply continuous, by using stored energy, such as from a battery. This can give you time to switch to using a generator in case of a more extended outage.

An online UPS is even better, as this kind of UPS shields equipment from even minor power fluctuations. Since the price for the higher-end UPS models has come down, there's little reason not to use them to protect any important network, especially since they typically have a longer battery life as well.

When buying a UPS, make sure to get the right size for the equipment you're protecting. Vendors have online wizards to help you find select the appropriate UPS, such as at While such sites are designed to sell specific products, you can still use them to get a general guideline for what size UPS you'll need.
