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).

Dual Device Mode
Dual Device Mode is only supported on models with two uplink ports.
When configured for Dual Device Mode, the module is configured as two logically
independent Layer 2 switches. Port F1 is associated with ports P1 and P2 and Port
F2 is associated with ports P3 and P4. Data flow will follow MAC address mapping.
Dual Device Mode
Configured for Dual Device Mode and Directed Switch Mode, the traffic from ports P1
and P2 is only forwarded to uplink port F1 and ports P3 and P4 are only forwarded
to uplink port F2. This prevents broadcast traffic from flooding other network ports.
Incoming traffic from F1 and F2 follows MAC address mapping.
