It is recommended to use IFS SFPs on the Industrial Managed Switch. If you insert an SFP
transceiver that is not supported, the Industrial Managed Switch will not recognize it.
1000Base-SX/LX:
Before connecting the other switches, workstation or media converter,
1.
Make sure both sides of the SFP transceiver are with the same media type; for example, 1000Base-SX to 1000Base-SX,
1000Bas-LX to 1000Base-LX.
2. Check the fiber-optic cable type that matches the SFP transceiver model.

To connect to 1000Base-SX SFP transceiver, use the Multi-mode fiber cable with one side being male duplex LC
connector type.
 To connect to 1000Base-LX SFP transceiver, use the Single-mode fiber cable with one side being male duplex LC
connector type.
Connecting the fiber cable
1.
Attach the duplex LC connector to the network cable and put into the SFP transceiver.
2. Connect the other end of the cable to a device – switches with SFP installed, fiber NIC to a workstation or a media
converter.
3. Check the LNK/ACT LED of the SFP slot on the front of the Industrial Managed Switch. Make sure that the SFP
transceiver is operating correctly.
100Base-FX:
Before connecting the other switches, workstation or media converter,
1.
Make sure both sides of the SFP transceiver are with the same media type or WDM pair, for example: 100Base-FX to
100Base-FX, 100Base-BX20-U to 100Base-BX20-D.
2. Check the fiber-optic cable type that matches the SFP transceiver model.
 To connect to 1000Base-SX SFP transceiver, use the Multi-mode fiber cable with one side being male duplex LC
connector type.
 To connect to 1000Base-LX SFP transceiver, use the Single-mode fiber cable with one side being male duplex LC
connector type.
Connecting the fiber cable
1 Attach the duplex LC connector to the network cable and put into the SFP transceiver.
2 Connect the other end of the cable to a device – switches with SFP installed, fiber NIC to a workstation or a media
converter.
3. Check the LNK/ACT LED of the SFP slot on the front of the Industrial Managed Switch. Make sure that the SFP
transceiver is operating correctly.
4. Check the Link mode of the SFP port if the link failed. Co works with some fiber-NICs or Media Converters, set the Link
mode to “100 Force” is needed.
2.5.2 Removing the Module
1. Make sure there is no network activity by consulting or checking with the network administrator. Or through the
management interface of the switch/converter (if available) to disable the port in advance.
2. Remove the Fiber Optic Cable gently.
3. Turn the handle of the MGB / MFB module to horizontal.
4. Pull out the module gently through the lever..
