1 Overview 1.1 Introduction The device is a hardened switch. It provides a high-performance switching engine and large buffer memory to ensure smooth video stream transmission. With its full-metal and fanless design, the device has great heat dissipation capabilities on its shell surface, and is able to work in environments that range from–30 °C (-22 °F) to +65 °C (+149 °F).
2 Port and Indicator 2.1 Front Panel The following figures are for reference only, and might differ from the actual product. Figure 2-1 Front panel (with PoE) Figure 2-2 Front panel (without PoE) Following are all the ports and indicators on the front panel of the 4/8-port unmanaged hardened switch.

Figure 2-3 Side panel (with PoE) Table 2-2 Port description (with PoE) Description PD Alive: When a terminal device crash is detected, the device will power down and restart the terminal device. Extend Mode: Extends the maximum transmission distance to 250 m, but reduces average transmission speed to 10 Mbps.
3 Installation The device supports DIN-rail mount. Hang the switch hook on the rail, and press the switch to make the buckle latch on to the rail. The width of the guide rail supported by the device is 50 mm. Figure 3-1 DIN rail Name Hook.
4 Wiring 4.1 Connecting GND Device GND connection helps ensure device lightning protection and anti-interference. You should connect the GND cable before powering on the device, and power off the device before disconnecting the GND cable. There is a GND screw on the device cover board for the GND cable. It is called enclosure GND.
Table 4-1 Power terminal description Name DIN rail port (–). DIN rail port (+). Power adapter port. Step 1 Connect the device to the ground. Step 2 Take off the power terminal plug from the device. Step 3 Insert one end of the power cable into the power terminal plug according to requirements. The sectional area of the power cable must be more than 0.75 mm (maximum sectional area is 2.5 mm...
Figure 4-2 SFP module structure Name Gold finger. Optical port. Spring strip. Handle. Figure 4-3 SFP module installation 4.4 Connecting Ethernet Port Ethernet port is a standard RJ-45 port. With its self-adaptation function, it can be automatically configured to full duplex/half-duplex operation mode. It supports MDI/MDI-X self-recognition of the cable, therefore, you can use a cross-over cable or straight-through cable to connect the terminal device to network device.
Figure 4-5 Cable connection 4.5 Connecting PoE Ethernet Port If the terminal device has a PoE Ethernet port, you can directly connect the terminal device PoE Ethernet port to the switch PoE Ethernet port through the network cable to achieve synchronized network connection and power supply.
Appendix 1 Cybersecurity Recommendations Mandatory actions to be taken for basic device network security: Use Strong Passwords Please refer to the following suggestions to set passwords: The length should not be less than 8 characters. Include at least two types of characters; character types include upper and lower case ...
