Optional features
SNMP interface card
An SNMP interface card can be placed in the rear panel of the UPS, and allows the data interface to be connected directly to
an Ethernet network.
When this option is installed the serial communication link is no longer available to the user.
Relay card
The relay plug-in card can be installed in the rear panel of the UPS. The card is provided with four potential free contacts
representing: battery low, bypass active, utility failure and general alarm.
Connectivity products
Interface kits (cables and/or software) are available for operating systems supporting JAVA and most commonly used
network operating systems, including Novell, UNIX, VMS, Windows platforms, IBM AS/400, IBM OS/2, LINUX.
