Cable Connection for a Single Device

• Plug the power cable into the device's rear panel, and then press the POWER button. At this time, the POWER indicator light (green) and the ALARM indicator light (red) on the front panel will be on. The ALARM indicator light will go out in one or two minutes, indicating that the device works.

• Connect the ETH0 interface to a computer with a standard RJ-45 Ethernet cable, then change the computer NIC to 10.251.251.x/24 segment, then configure the Network Secure device.

• Use standard RJ-45 Ethernet cable to connect the ETH2 interface to the Internet access device, such as routers, optical fiber transceivers, or ADSL Modem.

Precautions

  1. The multi-line Network Secure device supports multiple Internet lines. At this time, the ETH2 interface is connected to the second Internet access device. The ETH3 interface is connected to the third Internet line, and so on.
  2. Use the standard RJ-45 Ethernet cable to connect the DMZ interface to the DMZ network. Generally, the DMZ is equipped with web servers, e-mail servers, etc., that provide services for the outside.               Network Secure can provide security protection for these servers.
  3. When the device works, the POWER and LINK indicators for both the WAN and LAN interface will stay on. The ACT indicator will keep blinking when there is data traffic. The ALARM indicator is constantly red (for about one minute) only when the system loads after startup and goes out when the system is working. If the indicator light (red) stays on during installation, please power off and restart the device. If the red light is still on after startup, please contact us.
  4. Use a straight-through network cable to connect the WAN interface to the MODEM and a crossover Ethernet cable to connect to the router. Use a straight-through network cable to connect the LAN interface to the switch and a crossover Ethernet cable to connect to the networking interface of the computer. When the indicator light is in normal status and the connection fails, please check whether the cables are connected correctly. The difference between the straight-through network cables and the crossover Ethernet cables lies in the wire sequence at both ends of the cables as follows.
