Comms modules

Cause

There are three module locations available, how do these relate to the port numbers.

Resolution

The top location is associated with port 1 and this port is normally used for connection to the sub-lan.

The middle location is associated with port 5 and the port is normally used as the connection to the main network.

The bottom location is associated with port 6 and the port is used as the connection to the backup network.

In the screen shot below, the DNN (Ex-NIU) has an ARCnet module fitted into port 1 (Top). An Ethernet module is fitted into port 5 (Middle), and the lower location port 6 is not used.
