Ports
RJ-45 ports: Eight RJ-45 ports auto-sense for 10, 100 Mbps while two ports auto-sense for
10, 100 or 1000 Mbps device connections. The auto MDI/MDIX feature allows
connections to switches, workstation and other equipment without changing straight
through or crossover cabling. The charts below show the cable pin assignments for
straight through and crossover cables.
•RJ-45 Pin Assignments

1 Tx+
2 Tx-
3 Rx+
6 Rx-
Note “+” and “-” signs represent the polarity of wire pair.
All copper ports on the EIR418-2SFP-T support automatic MDI/MDI-X operation, you can
use straight-through cables (See Figure below) for all network connections to PCs or servers,
or to other switches or hubs. In straight-through cables, pins 1, 2, 3, and 6, at one end of the
cable, are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The
table below shows the 10BASE-T / 100BASE-TX MDI and MDI-X port pin outs.

•2 Gigabit Copper/SFP (Mini-GBIC) combo port:
The EIR418-2SFP-T has two auto-detect Giga ports—copper/Fiber combo ports. The
Gigabit Copper (10/100/1000T) ports should use Category 5e or above UTP/STP cable for
connection. The SFP slots support dual mode which can switch the connection speed
between 100 and 1000Mbps. These SFP slots can be used to connect the network segment
with single or multi-mode fiber. You must choose appropriate mini-GBIC module to plug
into the slots. Make sure the module is aligned correctly and then slide the module into the
SFP slot until a click is heard. With the SFP module (fiber optic connection), the switch can
transmits speed up to 1000 Mbps and you can prevent noise interference from the system
and get extended transmission distance, depending on the SFP module used.
Note The SFP/Copper Combo port can’t both be used at the same time. The SFP
module has the highest priority. If a 1000M SFP transceiver is inserted into the
SFP cage and a remote device is connected to the SFP port, the copper combo

port will link down. If a 100M SFP transceiver is inserted into the SFP cage the
copper combo port will link down regardless of the connection status of the
remote device.

To connect the transceiver and fiber cable, follow the steps shown below.
(Note: SFP modules typically terminate with an LC fiber connector)
First, insert the SFP transceiver into the SFP module cage. Notice that the triangle mark is at
the bottom of the module.
Make sure the module is aligned correctly and then slide the module into the SFP slot until
a click is heard.

Second, swivel the metal latch away from the switch and pull the transceiver out.
Pull out from the SFP module
Cabling
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable.
10Mbps: Use category 3, 4, 5 or greater cable
100Mbps: Use category 5 or greater
1000Mbps: Use category 5e or greater cable
Cable distances should be less than 100 meters (328 ft.) long.
Wiring the Power Inputs
Follow the steps below to insert the power wire.
1. Insert the positive and negative wires into the V+ and V- contacts on the terminal block
connector.

2. Tighten the wire-clamp screws for prevent the wires from becoming loose.
Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as shown below.
If one of the power sources fails a fault will be detected causing the circuit to open.
Note The wire gauge for the terminal block should be 12 to 24 AWG.
Insert the wires into the fault alarm contact (No. 3 & 4)

Mounting Installation
DIN-Rail Mounting
The DIN rail clip comes screwed on to the switch, from the factory. If the DIN rail clip is
not screwed on the switch, please see the following figure to re-attach the DIN-Rail clip.
Then follow the steps below to hang the switch onto a DIN rail.
1. Use the screws to screw the DIN rail clip onto the switch.
2. To remove the DIN rail clip, reverse step 1.

3. First, insert the top of DIN rail clip onto the piece of the DIN rail track.
4. Then, lightly push the bottom of the switch so it can snap the rest of the way onto the
DIN rail track.
5. Check that the switch is held tightly to the DIN rail track.
6. To remove the switch from the track, reverse the steps above.
•First pushing down lightly on the switch will give enough room for the bottom of
the switch to clear the bottom of the DIN rail track.

Mounting Installation

•Pulling slowly at the bottom of the switch will bring the switch out so that the
switch can now be carefully lifted off the DIN rail track.
Wall or Panel Mount Plate Mounting
Follow the steps below to mount the switch with the wall mount plate.
1. Remove the DIN rail clip from the switch; loose the screws to remove the DIN rail clip.
2. Place the wall mount plate on the rear panel of the switch.
3. Use the screws to screw the wall mount plate onto the switch.
4. Use the hook holes at the corners of the wall mount plates to hang the industrial switch
on the wall.
5. To remove the wall mount plate, reverse the above steps.

Hardware Installation
Installation Steps
1. Unpack the switch.
2. Check if the DIN rail clip is screwed on the Industrial switch or not. If the DIN rail clip
is not screwed onto switch, please refer to DIN-Rail Mounting section for DIN-Rail
installation. If the user wants to wall mount or panel mount the switch, then please refer
to Wall or Panel Mount Plate Mounting section for wall plate installation.
3. To hang the Industrial switch on the DIN-Rail track or wall, please refer to the
Mounting Installation section.
4. Power on the Industrial switch. Please refer to the Wiring the Power Inputs section for
knowing the information about how to wire the power. The power LED on the Industrial
switch will light up. Please refer to the LED Indicators section for indication of LED
lights.
5. Prepare the twisted-pair, straight through Category 5/above cable for Ethernet
connection.
6. Insert one end of UTP/STP cable into the Industrial switch RJ-45 port and the other end
to the network device’s RJ-45 port, e.g. Switch PC or Server. The RJ-45 port LED on
the Industrial switch will light up when the cable is connected with the network device.
Please refer to the LED Indicators section for LED light indication.
7. When all connections are set and LED lights all show in normal, the installation is
complete.
