1600XP/XPi Series Installation and Operation Manual – 60616-012
18.2 UPS LAN Shutdown Signal Operation
When the UPS stop signal is sent to the UPS through pin 2 and 3 of the external contact
interface, it is
possible to automatically reset the following operating systems (OS), which can automatically implement
the shutdown function and restart the operation:
Windows NT, IBM OS/2 LAN server, LANtastic
Parameter 646 – UPS Shutdown by LAN Input Signal Enabled/Disabled
Parameter 647 – UPS Shutdown by LAN Signal Permitted Time Window (Adjustable)
With the
UPS Shutdown by LAN Signal
function enabled, when line power fails and the UPS goes to
backup the LAN will shutdown even if the UPS returns to normal mode during the shutdown process.
LAN shutdown can take several minutes. The
UPS Shutdown by LAN Signal
function has a companion
UPS Shutdown by LAN Signal Permitted Time Window
parameter that can be set to allow sufficient
time to complete the LAN shutdown process (default: 10 minutes) even if line power is restored during
LAN shutdown.
LAN shutdown is treated as a restart after battery shutdown. The restart of the LAN will be determined
by the
Restart After Battery Shutdown
timer.
Connect only the UPS stop signal to the external contact interface for automatic processing so that the
UPS output will not be turned off by mistake.
If the computer is started/restarted within 10 minutes after the recovery from a power failure, the
power supply may be reset while the computer is restarting.
18.3 RS-232C
The RS232C port can be used by authorized service personnel. The port is provided using a DB9 female
connector located on the rear of the UPS. For reference, the pinout of the connector is illustrated below.
