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.
