Switch 3
When the FOT is being used as a RI/RO device this switch enables or
disables the autowrap feature on the RJ45 port. It has no relevance to
station/lobe applications. The feature should be enabled to connect to
Cabletron devices or disabled to connect to non-Cabletron devices.
Set Switch 3 as shown in the table.
Switch 4
This switch selects the mode on the entire FOT. Use the switch to
configure it as a RI/RO device or a station/lobe device. Then use Switch 2
to establish the configuration of the RJ45 port; the fiber ST port
configures automatically. Set Switch 4 as shown in the table.
