X-Slot Cards
X-Slot cards allow the UPS to communicate in a variety of networking environments and with different types of devices. The Powerware 9155 has two available communication bays for any X-Slot card, including:
ConnectUPSt-X Web/SNMP Card - has SNMP and HTTP capabilities as well as monitoring through a Web browser interface; connects to a twisted-pair Ethernet (10/100BaseT) network. It has a built-in switching hub that allows three additional network devices to be connected to the network without the requirement of additional network drops. In addition, a Powerware Environmental Monitoring Probe can be attached to obtain humidity, temperature, smoke alarm, and security information.
Relay Interface Card - has isolated dry contact (Form-C) relay outputs for UPS status: Utility failure, Low battery, UPS alarm/OK, or On bypass.
Modbus® Card - allows you to continuously and reliably monitor the UPSs in your Building Management System (BMS).
