When a network wire is cut, the ring is split into two – the switch / router automatically enables the port to maintain service.
This is shown below.

The switch / router can be configured to send an email message when port blocking is disabled thus signaling that a net-
work wire has been cut.
Connecting the Network Cable to the Controller
To connect controllers to an Ethernet network and then discover them, see chapter First Time Connection to an ECLYPSE
Controller.
Wireless Network Connection
The ECLYPSE Wi-Fi adapter connects to an ECLYPSE controller’s USB port.

It adds wireless IP connectivity to controllers and it can be used in many wireless topologies and applications.
To wirelessly connect to a controller for the first time, see First Time Connection to an ECLYPSE Controller.
To configure a Wi-Fi adapter, see Network Settings. See also chapter Configuring the ECLYPSE Wi-Fi Adapter Wireless Net-

Recommendations are provided regarding the radio signal obstructions and factors that should be avoided to obtain the
best Wi-Fi radio signal transmission and reception. Walls attenuate radio wave propagation by an amount that varies with
the construction materials used. See Radio Signal Transmission Obstructions for more information on wall materials that can
reduce range transmission.
