SW1 and SW2: Mode of Operation
The module supports Switch, Directed Switch and Dual Device modes.
The modes are described with MAC learning enabled. When MAC learning is
disabled, unicast packets are forwarded to all ports.

Modes of Operation
Switch Mode
When configured for Switch Mode (factory default), the module operates as a
standard layer 2 switch. Data flow will follow MAC address mapping.
Directed Switch Mode
When configured for Directed Switch Mode, traffic from all the RJ-45 user ports is
only forwarded to the uplink port F1, preventing the broadcast traffic from flooding
other network ports. Incoming traffic from F1 follows MAC address mapping.
Directed Switch Mode Single Uplink Port
For models with two uplink ports (copper or fiber), the data traffic on the additional
uplink port (F2) is also forwarded to port F1.

Directed Switch Mode Dual Uplink Port
When models with two uplink ports are configured for Directed Switch Mode and
Uplink Redundancy (per DIP-switches 3 and 4), traffic is forwarded to both the
primary and secondary uplink ports. The secondary port will block all traffic while
the primary port is active. When the primary port goes down, the secondary port
will be active and all traffic will be forwarded out the secondary port (F2).
