RemotEye Network Card
The RemotEye is an optional network card for Toshiba UPS. This card slides into a slot located on
the back side (pages 45-46) of the UPS. The card provides a network, or LAN-based
communication interface for the UPS. When installed, the UPS can be managed remotely using the
common SNMP and HTTP (web-based) network protocols. The following diagram shows the flow of
the Network Management Station.
Note:
The UPS communication mode setting must be set to “SNMP” mode when using the RemotEye
network card (See Comm Mode variable in the 'Data Setting Screens' on page 32 and 34).
