DB9 Port Connection
–Optional–*
Using the grey or tan Tripp Lite cable
that came with your UPS, connect
your primary server’s DB9 port to the
single DB9 port labeled “LAN 4.1”
(which provides complete intelligent
RS-232 communications).**
* Serial port connections are optional. Your UPS
will function properly without these
connections.
** The “LAN 4.1” DB9 port is always enabled
and is not controlled by the LAN Interface DIP
Switches.
If you have additional
computers:
Connect them to the DB9 ports
labeled “LAN 2.2” (which provide
basic, contact-closure shutdown
capabilities) using the black cables
that came with your UPS.
Set their corresponding LAN Interface
DIP Switches to the ACTIVATE
(DOWN) position. See diagram for
which switch controls which port.***
*** If you do not connect a computer to either of
the “LAN 2.2” DB9 ports, set their
corresponding LAN Interface DIP Switches to
the DEACTIVATE (UP) position.
Note: DIP Switch #3 has no function.
