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 9355
has two available communication bays for any X-Slot card, including:
S ConnectUPS -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.
S Relay Interface Card - has isolated dry contact (Form-C) relay outputs
for UPS status: Utility failure, Low battery, UPS alarm/OK, or On
bypass.

UPSs in your Building Management System (BMS).
