HP Accessory 651176-002 manual Obtaining new batteries, UPS battery replacement procedure

When a battery alarm sounds, initiate a UPS battery self-test to verify that battery replacement is required. If the Battery Fault LED remains illuminated, replace the batteries as soon as possible.

For more information on initiating a self-test, see "Initiating a self-test (on page 43)." For the location of LEDs, see "UPS front panel LED indicators (on page 8)."
