10.0OPTIONS

Several items of optional equipment are available for connection to the Liebert NX UPS.

10.1Communication and Other User Terminals

The UPS can be integrated into advanced networking environments via UPS monitoring software such as Windows-based UPS Monitor, MultiLink™, Nform™, SiteNet, Modbus / Jbus, SiteScan, SiteScan 2, SNMP, etc. They allow UPS status monitoring and automatic and safe shutdown of the server and PCs.

NOTE: The black square ( ) on each slot indicates Pin 1.

10.1.1Analog Input Interface

At the X6 slot, there are two analog signal channels. Input range is from 0 to +5V, and the precision is 2 percent. “ENV-T” is used for environment temperature detecting.

•X6 pin 1: Not used

•X6 pin 2: +12V

•X6 pin 3: ENV-T – environment temperature detection

•X6 pin 4: GND

10.1.2Power Output

The X5 slot can provide power for a modem or an external SNMP card. Available voltage is from 9V to 12V. The maximum current is 500mA.

10.1.3Liebert IntelliSlot Communication

The Liebert NX has three Liebert IntelliSlot ports to allow field-installation of optional communica- tion cards. Liebert IntelliSlot cards communicate via Liebert’s proprietary ESP2 protocol to cards that translate the information into such protocols as SNMP, IGMnet, Modbus or Jbus. Other cards provide dry contact signals for external signaling of operating status.

The Liebert IntelliSlot communication ports may be installed or removed while the Liebert NX is operating.
