UPS systems range in price from a few hundred dollars to several thousand dollars,
with the more expensive units allowing you to run larger systems for a longer period
of time when AC power is lost. UPS systems that provide only 5 minutes of battery
power let you conduct an orderly shutdown of the system, but are not intended to
provide continued operation. Surge protectors should be used with all UPS systems,
and the UPS system should be Underwriters Laboratories (UL) safety-approved.
If at any time you don't understand a procedure described in this guide or if the sys-
tem does not perform as expected, Dell provides a number of tools to help you. For
more information on these help tools, see “Getting Help” in your Installation and
Troubleshooting Guide.
