Selecting the IM7200 fiber or copper LAN ports

The IM7200 has dual 10/100/1000 GbE copper or Small Form-Factor Pluggable (SFP) fiber LAN ports.  

,

Each unit has four physical input ports (shown above) that are logically bundled as two ports (NET1 & NET2). Each logical port consists of a copper 10/100/1000 copper port and a fiber-optic small form-factor pluggable (SFP) module slot. Within each port, you can use only one of the two physical ports - either the NET1 (SFP) module port or the 10/100/1000 copper port NET1 (C).

The default operation is that if the SFP transceiver module is plugged in, the fiber-optic medium has the priority over copper medium. If the SFP module is not plugged in, then the copper medium becomes active. If the SFP module is plugged in later (even after the copper medium establishes the link), then the link of the copper medium will be disconnected and the fiber-optic medium will become active.

The SFP module does not have any specific activity LED of its own. However as each SFP is driven by the dual-mode fiber/copper PHY chip inside the IM7200, and we have been configured the LEDS on the copper RJ-45 GbE ports so they flash both for copper and for fibre traffic. Also at any time you can see which SFPs are active from SFP Information field in the IM7200 GUI Status: Support Report:

Opengear offers a selection of hot-pluggable SFP transceiver modules that plug into the SFP module sockets: 

#569023 SX SFP (550m range, 850nm Multimode),

#569024 LX/LH SFP (2km range, 1310nm Multimode),

#569025 LX/LH SFP (10km range, 1310nm Singlemode) and

#569026 EX SFP (40km range, 1310nm Multimode).

You can use any combination of SFP transceiver modules that match the wavelength specifications on the other end of the cable (as long as the cable does not exceed the stipulated cable length).
