Mini-GBIC combo port:
2 auto-detect Giga port—UTP or fiber. The gigabit Ethernet ports are hared with the mini-GBIC ports. UTP (Gigabit Ethernet) ports can
operate in half/full-duplex modes and work at speeds of 10/100/1000Mbps that support auto-sensing technology to enable each port to detect
the connecting speed. The mini-GBIC port is a joint for a mini-GBIC (SFP) transceiver, so the switch can be uplinked through fiber to another
one.
Use four twisted-pair, Category 5e or above cabling for RJ-45 port connection. The cable between the switch and the link partner (switch,
hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
Use the mini-GBIC ports to uplink to another switch by inserting the mini-GBIC (SFP) transceiver.

DIN-Rail Mounting
The DIN-Rail is screwed on the industrial switch when out of factory. If the DIN-Rail is not screwed on the industrial switch, please see the
following pictures to screw the DIN-Rail on the switch. Follow the steps below to hang the industrial switch.
1. First, insert the top of DIN-Rail into the track.
2. Then, lightly push the DIN-Rail into the track.
3. Check if the DIN-Rail is tightened on the track or not.
4. To remove the industrial switch from the track, reverse steps above.

Wall Mount Plate Mounting
Follow the steps below to mount the industrial switch with wall mount plate.
1. Remove the DIN-Rail from the industrial switch; loose the screws to remove the DIN-Rail.
2. Place the wall mount plate on the rear panel of the industrial switch.
3. Use the screws to screw the wall mount plate on the industrial switch.
4. Use the hook holes at the corners of the wall mount plate to hang the industrial switch on the wall.
5. To remove the wall mount plate, reverse steps above.

Assembly, Startup, and Dismantling
Wall Mounting Kit installation
Assembly: Securely fasten the wall-mount kits to the bottom of module by using the provided screws (6 pcs)
Mount the standalone unit onto a fixture, e.g. a plank, (either on the wall or on a flat surface) with at least 2 screws piercing
through the holes on the mounting frame to secure it in position.
Startup: Connect the supply voltage to start up the Media Converter via the terminal block.
Dismantling: Locate and remove the securing screws. Usually, but not limited to, at least 2 screws.
DIN rail installation (Optional)
Assembly: Place the Media Converter on the DIN rail from above using the slot. Push the front of the Media Converter
toward the mounting surface until it audibly snaps into place.
Startup: Connect the supply voltage to start up the Media Converter via the terminal block.
Dismantling: Pull out the lower edge and then remove the Media Converter from the DIN rail.
