Liebert UPSTATION GXT 2U - Manual (Page 22)

3. A battery shutdown signal on Pin 4 will NOT cause an immediate
shutdown. A shutdown signal will start a 2-minute shutdown timer.
The timer cannot be stopped. After 2 minutes, the UPS will shut
down.
4. If the utility returns during the 2-minute timer countdown, the shut-
down timer will continue until the end of 2 minutes and the UPS will
turn OFF. The UPS must remain OFF for at least 10 seconds even if
AC input power returns before the UPS turns OFF. This serves to
reset and restart the server.
Whether the UPS turns back ON when power is restored depends on the
auto-restart setting: enabled or disabled.
If the auto-restart is disabled, the UPS will not restart after performing the
2-minute shutdown delay.

OMMUNICATIONS
The UPStation GXT 2U is equipped with an Intellislot™ port to provide
advanced communication and monitoring options.
Liebert's MultiLink™ software continually monitors the UPS and can shut
down your computer or server in the event of an extended power failure.
MultiLink can also be configured for use without the serial cable when the
Intellislot SNMP/Web card is installed in the UPS. Additionally, MultiLink
can be configured to coordinate shutdown across the network with other
computers running MultiLink when you purchase a MultiLink License Kit.
For more information about the Intellislot SNMP/Web Card and MultiLink
License Kits, visit our Web site (www.liebert.com) or contact your local
dealer or Liebert representative.
Several option cards are available for use in the Intellislot port of the
UPStation GXT 2U. The Intellislot SNMP/Web Card provides SNMP and
Web-based monitoring and control of the UPS across the network.
The Intellislot MultiPort 4 Card allows you to install MultiLink software on
four computers and coordinate shutdown in the event of a power failure.
The Intellislot Relay Card provides five dry contact relay outputs for
custom wired applications and delivers support for built-in shutdown for
AS/400 systems.

CAUTION
To maintain safety (SELV) barriers and for
electromagnetic compatibility, signal cables should be
segregated and run separate from all other power
cables, where applicable.
