Turning the UPS Off

To turn off the UPS, press and hold the Off button until the long beep ceases (approximately five seconds). The indicator begins to flash and the UPS remains in Standby mode until you unplug the UPS from the power outlet.

Initiating the Self–Test

NOTE. The batteries must be fully charged to perform the self–test.

Press and hold the On button for three seconds to initiate the self–test. During the test, individual indicators illuminate as various parts of the UPS are checked. If the alarm beeps or a UPS alarm indicator stays on, see Table 2 on page 22.

Communication Port

The Powerware 5125 is factory-installed with a Single-Port Module.

To establish communication between the UPS and a computer, connect your computer to the UPS communication port using the supplied communication cable.

When the communication cable is installed, power management software can exchange data with the UPS. The software polls the UPS for detailed information on the status of the power environment. If a power emergency occurs, the software initiates the saving of all data and an orderly shutdown of the equipment.

The cable pins are identified in Figure 8 and the pin functions are described in Table 1.
