System Enable Switch (DIP Switch #4)
This switch is located in the set of 4 switches next to the UPS’s DB9
ports. It activates the battery charger and intelligent microproces-
sor. Always leave it in the “ENABLE” (UP) position when your UPS
is plugged in. Set the switch to “DISABLE” (DOWN) only if you store
or ship your UPS (to reduce battery drain).
Note: the “
XXX
” light will flash until you engage the ON/Standby Switch to activate the “ON”
mode (power ON at the UPS receptacles).

DB9 Port Connection
–Optional–*
Using Tripp Lite cable, connect your
primary server’s DB9 port to the
single DB9 port labeled SMART/LAN
4.1 (which provides complete
intelligent RS-232 communications)
using the included cable labelled
73-743.**
If you have additional
computers:
Connect them to the DB9 ports
labeled BASIC/LAN 2.2 (which provide
basic, contact-closure shutdown
capabilities) using the included
cables labelled 73-844.
Set their corresponding LAN Interface
DIP Switches to the ACTIVATE
(DOWN) position. See diagram for
which switch controls which port.***
* Serial port connections are optional. Your UPS will function properly without these connections.
** The SMART/LAN 4.1 port is always enabled and is not controlled by the LAN Interface DIP Switches.
*** If you do not connect a computer to either of the BASIC/LAN 2.2 ports, set their corresponding LAN Interface DIP
Switches to the DEACTIVATE (UP) position. Note: DIP Switch #3 has no function.
