Product description
This series isThis switch is an unmanaged rack-mount industrial Ethernet switch.MIEN3020G-4GC-16GT(4 Gigabit Combo ports+16 Gigabit RJ45 ports), MIEN3028G- GC-24GT provides 28 ports (4 Gigabit combo ports+24 Gigabit RJ45 ports).
Interface description
Unit:mm
Take MIEN3028G-4GC-24GT as a example:
| 1. Indicator lights | 5.Power input terminal |
| 2.Gigabit RJ45 port | 6. Ground screw |
| 3. Gigabit combo port | 7. Rack mounting ears |
| 4. Relay alarm output terminal |
[Connect the power]
The switch supports AD220V single power input, using 5-position locking terminals with 5.08mm pitch.
| Number | Pin definition |
| 1 | Power 1 Input V1+(AC-L)/Positive(DC) |
| 2 | Power 1 Input V1-(AC-N)/Negative (DC) |
| 3 | Grounded |
| 4 | Power 2 Input V2+(AC-L)/Positive(DC) |
| 5 | Power 2 Input V2-(AC-N)/Negative (DC) |
[Connect to the relay]
This series of switches supports the relay alarm function, and the wiring terminals use 3-position 5.08mm pitch terminals. This relay is a normally open and a normally closed elay, the middle one is the common terminal, the left two terminals are normally open relays, and the right two terminals are normally closed relays. When the switch is orking normally, the normally open relay is powered and closed, and the normally closed relay is disconnected. The recommended switching load capacity of the relay is 1A (24VDC).
| Number | Pin definition |
| 1 | Alarm relay output normally open |
| 2 | Alarm relay output common terminal |
| 3 | Alarm relay output normally closed |

Hardware Installation
Installation Precautions
To prevent equipment damage or personal injury caused by improper use, observe the following precautions:
- During the installation process, you need to wear anti-static gloves or anti-static gloves, and power-off the switch.
- Please make sure that the input voltage is within the input voltage range marked on the switch.
- The transmission distance has a certain relationship with the connected wire. It is recommended to use a standard Cat5e/6 network cable.
- The equipment must be grounded for lightning protection, otherwise the protection level of the equipment will be greatly reduced; please use a wire of No.20 or more to connect the grounding terminal to the ground.
- The power line, ground line and signal line are laid out separately and the distance is not less than 5cm
[Device installation]
Install rack-mounted equipment
Rack-mounted installation, the installation steps are as follows:
- Step 1 Select the installation location of the device and make sure it has sufficient size.
- Step 2 Use 2 screws to install the mounting ear to the position of the device as shown in the figure below.
- Step 3 Put the device on the rack, and use 4 screws to fix the left and right side brackets to the rack respectively.
- Step 4 Check and confirm that the product is securely installed on the rack, and the installation is complete.
[Device connection]
- Step 1 Connect one end of the ground wire to a suitable position, and fix the ground plate on the switch panel with washers and screws.
- Step 2 Connect the power cord to the switch’s power terminals.
- Step 3 Connect the network cable to the RJ45 port of the switch.
- Step 4 Insert the SFP optical module into the SFP port and connect the fiber-to-fiber transceiver.
