Method step
1, after purchasing the equipment, unpack and check whether the equipment and accessories are complete. ZXHN F420 host (including base), power adapter, RJ-45 network cable and RJ- 1 1 telephone line.
2. Detailed explanation of the meaning of ZTE ZXHN F400 optical network equipment indicator light:
Power indicator (green): Always on? Turn on the power. Put it out? Turn off the power.
Network e (green): always online? Device registered successfully. Blink? Equipment composition. Put it out? Device registration failed or the system is not powered on.
Signal light (red): Always on? The optical power received by the device is lower than the sensitivity of the optical receiver. Put it out? The device receives normal optical power.
Alarm (red): Always on? The device is not started or faulty. Blink? Version upgrade or version download. Put it out? The equipment is running normally.
3. Gateway 1, iTV, Gateway 3, Gateway 4 (green): flashing? Indicates that there is data transmission. Always bright? The network port is connected, but there is no data transmission. Put it out? The network port is not connected with a network device (or is not powered on). Voice 1, voice 2 (green): flashing? There is traffic flow transmission. Always bright? Successfully registered to Softswitch, but there is no service flow. Put it out? No connection is established (or the device is not powered on)
4. Turn on the regulated power supply (the voltage fluctuation must be less than 10%, otherwise it will lead to unstable operation of the equipment) and turn on the power button.
5. Schematic diagram of telephone wiring (voice 1, voice 2).
6. Schematic diagram of the connection between the computer and the TV set-top box.
7. Wiring diagram of network, telephone and TV (you can surf the Internet normally after connection, generally there is no wireless network, so you need to buy your own router if you need WiFi).
8. After turning on the power, enter:192.168.438+0.5438+0 in the browser address bar of the computer? Enter to open the settings management interface (as long as you can access the Internet, try not to set it yourself).
9. If the equipment is installed by staff, usually enter the correct logical ID and password to activate the optical network equipment.

Because the router is the key equipment in the network, in view of various security risks in the network, the router must have the following security features:
(1) Reliability and line safety reliability require fault recovery and load capacity. For routers, reliability is mainly reflected in two situations: interface failure and increased network traffic. Therefore, backup is one of the indispensable means for routers. When the main interface fails, the backup interface automatically works to ensure the normal operation of the network. When the network traffic increases, the backup interface can also undertake the task of load sharing.
(2) Authentication in the authentication router mainly includes authentication when accessing the router, authentication of the opposite router and authentication of routing information.
(3) Access Control For the access control of routers, hierarchical password protection is required. There are IP address-based access control and user-based access control.
(4) When hiding information and peer-to-peer communication, there is no need for real identity communication. With address translation, you can hide the internal address and access the external network only through the public address. Except for the connection initiated by the internal network, users outside the network cannot directly access the resources in the network through address translation.
(5) data encryption
In order to avoid information leakage caused by data eavesdropping, it is necessary to encrypt the transmitted information, and only the opposite end communicating with it can decrypt the ciphertext. By encrypting the message sent by the router, the privacy and integrity of the data and the authenticity of the message content can be guaranteed even if it is transmitted on the Internet.
(6) Attack detection and prevention
As the external interface device of the internal network, the router is the first target for an attacker to enter the internal network. If the router does not provide attack detection and defense, it is also a bridge for attackers to enter the internal network. Providing attack detection on the router can prevent some attacks.
