12.1.3 Liebert IntelliSlot Communication
The Liebert NX has three Liebert IntelliSlot ports to allow field-installation of optional
communication 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.
