Liebert SN sensors are designed to assist in monitoring conditions within a rack - sensors can be placed in any area whilst being monitored through a secure Web/SNMP interface, the RPC BDM Local Display Module, or through Liebert Nform / SiteScan software. Up to 10 Sensors can be connected to a Liebert RPC network card, enabling monitoring through Liebert MPX, MPH or MPH2 rack PDU models. SN Sensors are also compatible with the Liebert RDU‑S Rack Monitoring Device.HeaderBrand:LiebertCompatibility:PCManufacturer:LiebertModel:SN-3CPackaged Quantity:1Product Line:LiebertMiscellaneousCategory of Accessory:Racks and rack hardwareMounting Kit:IncludedPackage Content:Sensor cable (2m)Product Type:Dry contact sensorDimensions & WeightDepth:0.7 inHeight:1.6 inWeight:3.88 ozWidth:2 inTitleLIEBERT SN MODULAR SENSORS SN-3C Three Dry ContactConditionNewContentSensor with accessoriesManufacturerEmersonModelSN-3CSKUNRLB001 #1092_100-106http://www.compeve.com/Products/UPS/Accessories/Sensors/SN-3C/SN-3C_compeve__1.jpg
