57UPS Network Management Card 2 User’s Guide
Tests menu
Testing and calibrating
Path: Tests > UPS
This option is not available for all UPS devices.
With some UPS devices, you can run a self-test, an alarm test, or a runtime calibration for your UPS. The Self-
Test and Calibration fields display the results of the most recent test and calibration.
A runtime calibration causes the UPS to recalculate its available runtime capacity based on its current load.
This ensures that the runtime reported is more accurate. Because a calibration temporarily depletes the UPS
batteries, you can perform a calibration only if battery capacity is at 100%. The load on your UPS must be at
least 15% without fluctuating to guarantee that a calibration will be accepted.
Caution - Runtime calibrations deeply discharge UPS batteries, which can leave a UPS temporarily
unable to support its equipment if a power outage occurs.
Frequent calibrations reduce the life of batteries.
Perform a calibration whenever you significantly increase the load that the UPS is supporting.
The alarm test for a UPS is device-specific and might not be available for your UPS. To enable the alarm, see
“UPS General screen”.
When you select UPS Alarm Test, the UPS beeps for four seconds and the LEDs illuminate.
When you select UPS Alarm Test - Continuous, the UPS beeps and illuminates the LEDs until you
cancel the test. A separate bullet displays on this screen, Cancel Continuous Alarm Test. To cancel
the test, select this and click Apply. Alternatively you press any key on the LED display interface of the
UPS. This test is useful for locating a UPS.
Setting the NMC LED lights to blink
Path: Tests > Network > LED Blink
If you are having trouble finding your UPS device, enter a number of minutes in the LED Blink Duration
field, click Apply, and your NMC LED lights will start flashing. This can assist in locating the physical device.
