Systems Reference and Troubleshooting Guide
NOTE: Use a UPS to protect your computer only. Connect other devices, such as a
printer, to a separate power strip providing surge protection. The length of time that
the battery can supply power following an AC power loss decreases with additio n al
hardware.
UPS systems can cost a few hundred dollars to several thousand dollars, depending
on the operating time they provide when AC power is lost. UPS systems with 5 min-
utes of battery power let you conduct an orderly shutdown of the system, but they
are not intended to provide continued operation. A UPS system should be Underwrit-
ers Laboratories (UL) safety-approved.
