Checking UPS Status LEDs
Complete the following steps to check the UPS status.

2. Remove the cover.
3. Verify that the internal power switch is on.
4. Verify the status LEDs inside the UPS. See Table 10.
Description LED Indicators
DC output is OK Green LED turns on
Battery is being charged (AC input ok) Amber LED blinks slowly
Battery is being discharged (AC input failure) Amber LED blinks rapidly
DC output is faulty Red LED turns on
Table 10 – UPS Status LEDs
5. Verify that the UPS is producing the correct voltage at the
output terminals by measuring across DC+ and DC-. The
voltage should measure 13.6 to 14.4 VDC.
Verify that the AC input is present and the UPS's internal
switch is on (for example, battery should be charging).
6. If the AC input voltage is not present, then the voltage across
DC+ and DC- should measure 10.5 to 12.8 VDC.
7. If the DC voltage is not present across DC+ and DC-, then:
l
Measure the AC input voltage across L1 and N1. This
voltage should measure 120 VAC (± 20 V).
l
Verify that the UPS's internal switch is on.
l
Verify the UPS status LEDs. See Table 10.
8. Install the UPS cover again and secure it with the two screws.
