OSD NETWORKS OSD2258EP Operator's Manual page 19

To connect the OSD2258EP in a redundant ring configuration ports 9 and 10 must be used
together with fiber SFPs. The non-ring ports (ports 1 to 8) should be used to connect to your
Ethernet devices (eg. Cameras, PLCs, computers, etc.)
Figure 15 shows the connection method. Typically, the SFP used would be a fiber SFP with
duplex LC connectors. The dashed line indicates the closed loop, but more OSD2258EP units
can be connected to the ring as required using this topology. Ensure that the switch settings
for port 9 and 10 are set to 1000Mbps (1Gbps) – see Table 5. Note: connection diagram is for
illustrative purposes only. Port 9/10 can be connected in to either port to achieve redundant
ring configuration.
Bus Operation
To connect the OSD2258EP in a bus configuration ports 9 and 10 must be used together with
fiber SFPs. The remaining ports (ports 1 to 8) should be used to connect to your Ethernet
devices (eg. Cameras, PLCs, computers, etc.)
