Connect the NV-450M(Master) and the NV-450S(Slave) to the Line
The objective for LAN extender is to pass high speed data over a twisted pair cable. In the setup, connect NV-450M(Master) to NV-450S (Slave) through phone wire(24~26 AWG) or line simulator or any other hardware representation of a cable network, with or without noise injection and crosstalk simulations.

 

Proper Installation: Train & Metro Stations、Boat and Submarine、Parking system、Weather station、

Amusement park、Farm、Jail & Oil Refinery、Telecom.

1. POWER indicator does not light up (green) after power on.

 

Check the power plug by plugging in another that is functioning properly. Check the power cord with another device. Check the terminal block make sure to fasten the power cord. If these measures fail to resolve the problem, have the unit power supply replaced by a qualified distributor.

 

2. NV-450M/S both cannot handsharking after making a connection.

 

    1. 2.1 Verify that the switch and attached device are power on.
    2. 2.2 Be sure the cable is plugged into both the switch and corresponding device.
    3. 2.3 Verify that the proper cable type is used and its length does not exceed specified limits.
    4. 2.4 Check the modem on the attached device and cable connections for possible defects.
    5. 2.5 Make sure that the phone wire must be connecting NV-450S first, when powered on.
    6. 2.6 Replace the defective modem or cable if necessary.
2.7 Checking Phone wire length if exceed 600m(1968ft)

 

3. Line Link cannot be established.

 

  1. 3.1 Please make sure that the phone wire must be connected between NV-450M(Master) side and NV-450S(Slave) side when both are power on. NV-450M Master side will do link speed function depending on phone wire length, therefore if NV-450M Master side can’t detect Slave Side over phone wire while both power on, this will cause the Link to fail.
  2. 3.2 Please check phone wire, we recommend use 24-26 gauge with twisted pair and without rust.
  3. 3.3 Please reinsert power when change cable length or link time over 3 minutes.
3.4 If NV-450S connect to IP-DSLAM and link failure, please try to change band profile as 17a for getting long reach.
  1. .
4. I just bought a NV-450M/ NV-450S to replace my Quest DSL modem for my home. I was told any VDSL2 modem would replace and give me higher communication speeds. It doesn’t get me internet when hooked up. All lights come on but no Link light. Is this the complete wrong application for this unit?

 

Please note NV-450S is a Slave (CPE side), it must be connected to the NV-450M Master(CO side) or IP-DSLAM to get link.

 

5.We need to set up a default gateway on a NV-450M/ NV-450S pair which are in Bridge mode, as they want to manage the units from a different network.

 

When the application is used within the LAN, the switch(bridged) mode is not necessary to set up a gateway .However, if the application crosses various network segments (LAN to WAN(Line) or WAN(Line) to LAN), you must set up a gateway to connect different network segment.
Regarding how to configure a default gateway at switch(bridged) mode for crossing various network segments .
Configuration gateway example from Static Routing:
Destination LAN IP: 0.0.0.0
Subnet Mask: 0.0.0.0
Gateway:  192.168.16.1

Note: Static Routing functionality is used to define the connected Gateway between the LAN and WAN.

6. What can I do if I forgot my password.

 

If you forgot your password, you must reset your modem. Unfortunately this process will change all your settings back to the factory defaults. To reset the modem, locate the reset on the rear panel of the unit. With the modem powered on, use a paperclip to hold the button down for over 5 seconds. Release the button and the modem will go through its reboot process. NV-450M default ip is  192.168.16.249. NV-450S default ip is 192.168.16.254.When logging in, the default username and password both are “admin”.

 

7. What is the maximum Ethernet frame MTU for these modems?
  2. NV-450M / NV-450S jambo frame(MTU) up to 1600 bytes.
