Connecting to the Communications Port

The 3000 Series UPS models include a communications port for data exchange with the host computer.

IMPORTANT: Compaq Power Management Software, LanSafe III, and FailSafe III require the communications port to be appropriately cabled to the host computer.

Connect the UPS/computer interface cable (supplied) from the communications port on the UPS to the appropriate communications port on the host computer.

CAUTION: To avoid damaging the equipment, do not use the communications cables (part numbers 142260-001 and 142260-002) supplied with earlier UPS models. The UPS/computer interface cable is required to carry power and is wired differently than earlier communications cables.
