allow for a
controlled shutdown, they also offer surge protection. Computer equipment is very susceptible to
damage from power surges which may not be covered by your maintenance
agreement. It is highly recommended to
plug all mission critical devices (store controllers, servers, network
switches, registers, etc.) into a UPS.
In the event of a power loss the devices plugged into the
battery backup side of the UPS will be supplied battery power for a limited
amount of time. This will allow you to
finish up any transactions or functions you may be doing, so you can then
perform a controlled shutdown until power is re-established. Battery backup time can vary depending on the
model and voltage of the equipment plugged into the UPS. While providing battery support the UPS beeps
to alert you of the condition, so if needed, corrective action can be
taken. The UPS will also beep when it is
nearing the end of its battery life. It is
a good idea to periodically test to ensure it is in good working condition.
