• X6 pin 1: Not used
• X6 pin 2: +12V
• X6 pin 3: ENV-T – environment temperature detection
• X6 pin 4: GND
10.1.2 Power 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.
10.1.3 Liebert 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.
