7.0 OPTION INSTALLATION
7.1 Liebert IntelliSlot Communication
The Liebert
®
APM
™
has three Liebert IntelliSlot ports to allow field-installation of optional
communication cards. Liebert IntelliSlot cards communicate via Liebert’s proprietary Velocity
protocol to cards that translate the information into such protocols as SNMP and Modbus. 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 APM is
operating.
7.2 Liebert IntelliSlot Web Card—SNMP/HTTP Network Interface Card
This network interface card provides all real-time data and status information as SNMPv1 traps for
connection to a 10/100-baseT Ethernet connection. The same card also will transmit the same status
information and all measured parameters for display via a Web browser. The Liebert IntelliSlot bays
are on the right side of the control module and labeled as IntelliSlot1, IntelliSlot2 and IntelliSlot3.
