SNMP
The Simple Network Management Protocol (SNMP) communication interface is available as an option.
The Toshiba SNMP card slides into the SNMP port located on the back side of the UPS (see page 44
for SNMP port location). This optional interface allows the UPS to be monitored across the network
via SNMP to a Network Management Station (NMS). The following diagram shows the flow of the
Network Management Station.

card (See Comm Mode variable in the 'Data Setting Screens' on page 30 and 32).
