UPS Battery
The UPS batteries provide power to the Back End Processor to enable a controlled shut down of the
processor.
The UPS batteries will drain slightly when the system is in the off condition. The off condition is defined
as:
•
Circuit Breaker in the OFF position
•
System unplugged from the wall outlet
If the system is left in the OFF condition for an extended period of time (3 to 5 days or more), the system
may not boot up or may beep when turned ON. Should this occur, the system needs to recharge the
UPS batteries. This could take 15 minutes to as long as 24 hours, depending on the battery age, system
input voltage and system temperature. To eliminate draining the UPS batteries, the system should
remain plugged into the wall outlet with the circuit breaker in the ON position.
