11.1.2 Communications—Liebert SNMP/OCWEBCARD SNMP Adapter

Attach the larger enclosed ferrite bead clamp to the network cable, see illustration at right, using the following directions:

1.Open the ferrite bead.

2.Place the network cable inside the ferrite bead groove.

3.Wrap the cable once around the ferrite bead.

4.Position the ferrite cable as close as possible to the end of the cable that connects to the UPS.

5.Close the ferrite bead so that the ferrite bead’s case snaps closed with the cable routed through the ferrite bead’s case.

11.2Pin 4 - Remote Shutdown on Battery

Wrap network cable around ferrite bead

1.This pin is functional only when the UPS is in battery

mode. If the UPS is being powered by the utility, Pin 4 will ignore any signal on this pin.

2.Pin 4 requires a 5-12 VDC signal to shutdown. This normally comes form the serial port using Liebert’s contact closure cable. It cannot be used with just a contact closure unless the relay is used to switch a voltage source. A 5-12 VDC signal for 1.5 seconds or greater is required to signal a shutdown. Signals for less than 1.5 seconds will be ignored. After Pin 4 receives a shutdown signal for 1.5 seconds, the command cannot be canceled.

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 shutdown 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.

11.3UPS Intelligent Communications

The Liebert GXT2-10000RT208 is equipped with a Liebert IntelliSlot® port to provide advanced com- munication 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.

Liebert MultiLink can also be configured for use without the serial cable when the Liebert IntelliSlot SNMP/OCWEBCARD is installed in the UPS. Additionally, Liebert MultiLink can be configured to coordinate shutdown across the network with other computers running Liebert MultiLink when you purchase a Liebert MultiLink License Kit. For more information about the Liebert IntelliSlot SNMP/ OCWEBCARD and Liebert 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 Liebert IntelliSlot port of the Liebert GXT2-10000RT208. The Liebert Intellislot SNMP/OCWEBCARD provides SNMP and Web-based monitoring and control of the UPS across the network.

The Liebert IntelliSlot MultiPort 4 Card allows you to install Liebert MultiLink software on four com- puters and coordinate shutdown in the event of a power failure.

The Liebert IntelliSlot Relay Card provides 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.
