port or through an X-Slot card in one of the available bays.
The UPS supports two serial communication devices according to the following table:

Any X-Slot card
NOTE You can configure relays, signal inputs, and the serial port baud rate through the front panel menus
(see Table 9 on page 96).
NOTE In a UPS connected to utility power, X-Slot cards remain powered on even if the input breaker is off.

DB-9 Communication Port

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.
Figure 75 identifies the cable pins and Table 12 describes the pin functions. See
Figure 73 on page 107 for the communication port location.
