Installation Procedure
1) Configure DIP-switches
2) Installing the Module
3) Apply Power
4) Connect Cables
5) Verify Operation
1) Configure DIP-switches
DIP-switches are located on the side of the module. The DIP-switches are used to
configure modes of operation and networking features.

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. The data traffic on the additional uplink port (F2) is also forwarded
to port F1. Incoming traffic from F1 follows MAC address mapping.
Directed Switch Mode Dual Uplink Port
When 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).
