Single Temperature Probe The Liebert SN product line offers a wide range of sensors for temperature, humidity leak detection and other readings. Liebert SN sensors are designed to assist in monitoring conditions within a rack or network closet and can be placed in any area to read temperature and humidity levels, and digital inputs. Sensor wiring connects to the Liebert RPC card, which enables monitoring through Liebert MPX or MPH rack PDU models. It also connects to the IS-UNITY-DP communications card. Integrated sensors: Are attached to a single cable and are available in these versions: one temperature probe; three temperature probes; and three temperature probes plus one humidity probe. These sensors may be placed in any area, including within a rack, to monitor temperature and humidity levels. Compatible Liebert Products Liebert SN integrated sensors are compatible with the following products: Liebert MPX — an Adaptive Rack PDU (power distribution unit) built with modular and scalable components that can be installed and reconfigured on-site to meet varying input and output power connectivity needs. The Liebert RPC (Rack PDU Card) is an optional accessory for the Liebert MPX, but is required for connecting the Liebert SN. Liebert MPH — a single unit with fixed capacity, input and output. The Liebert RPC is factory installed in the Liebert MPH Liebert IS-UNITY-DP communications card: Liebert IntelliSlot Unity Communications Interface Card provides Web access and third-party customer protocols for Emerson Network Power equipment.
