Figure 3-5. Bad Battery/Low Battery LED
Verify that battery replacement is required by initiating a UPS self-test (press the
TEST/ALARM RESET button). If the red LED is still flashing after the test, replace the
batteries.
NOTE:
Depending on usage and environmental conditions, the batteries should last three to six years.
The battery packs are accessed from the front of the unit.
NOTE:
Batteries can be replaced (hot-swapped) without powering off the UPS if the UPS is not supplying
battery power to devices (utility is present, indicating that the UPS is supplying utility power). To replace
batteries with the UPS power off, follow the procedure in “Powering Down the UPS,” in this chapter.
