Troubleshooting

Q1: POWER LED does not illuminate after the product is turned on. What should I do?

A1: Verify that you are using the power cable provided with the device and that it is securely connected to the ADSL2+ modem and a wall socket/power strip.

Q2: I am not sure what type of Internet broadband connection I have for my DSL

connection. How do I find out?

A2: You can contact your Internet Service Provider's (ISP) Customer Service or Technical Support Department for the correct information.

Q3: I specified the IP address 192.168.1.254 in my Web browser, but an error messages says, "The page cannot be displayed. How can I get into the TDM-E400 / TDM-C400 web configuration page?

A3: Please check your hardware and TCP/IP settings again by following the instructions in the QIG. Make sure the Power, WAN and the LAN LEDs are on. Then try to access the configuration page using your Web Browser again.

Q4: INTERNET LED does not illuminate after phone cable is attached.

A4: Verify that a standard telephone cable (called an RJ-11 cable) like the one provided is securely connected to the ADSL port and your wall phone jack. Allow about 30 seconds for the device to negotiate a connection with your ISP.

Verify that you are using a straight-through type Ethernet cable to the uplink port on a hub or a cross-over type cable to a stand-alone PC. If you connected the device to an ordinary hub port (not Uplink), you must use a straight-through cable. (To check: hold the connectors at each end of the cable side-by-side with the plastic spring facing down. Looking at the wires from left to right, if the first, second, third, and sixth wires are the same color on the two connectors, then it is a straight-through type. On a cross-over type, wire 1 on one connector should be the same color as wire 3 on the other. The same is true of wires 2 and 6.)

Q5: Ethernet LED does not illuminate after Ethernet cable is attached.

A5: Verify that the Ethernet cable is securely connected to your LAN hub or PC and to the ADSL2+ mdoem. Make sure the PC and/or hub is turned on.

Verify that your cable is sufficient for your network requirements. A 100 Mbps network (10BaseTx) should use cables labeled CAT 5. A 10Mbps network may tolerate lower quality cables.

Q6. My LAN PCs cannot display web pages on the Internet.

A6: Verify that the DNS server IP address specified on the PCs is correct for your ISP, as discussed in the item above. If you specified that the DNS server be assigned dynamically from a server, then verify with your ISP that the address configured on the ADSL2+ modem is correct, then you can use the ping utility, described on page 174 of the user guide,

to test connectivity with your ISP's DNS server.

TDM-E400 specifications

The TRENDnet TDM-E400 is a robust and versatile network device designed to enhance the functionality and performance of small to medium-sized networks.

One of the standout features of the TDM-E400 is its capability to transmit Ethernet signals over existing coaxial cable, which can significantly reduce installation costs and time. This allows for seamless integration into environments where coaxial cabling is already in place, such as older buildings or setups where running new cables is not feasible. The TDM-E400 supports long-distance Ethernet transmissions, extending connections up to 4,000 feet (1,220 meters) over coaxial cable.

This device operates using advanced technology that ensures high-speed data transmission. It supports both 10/100 Mbps Ethernet connections, accommodating standard networking needs. The TDM-E400 includes features like auto-sensing and automatic MDI/MDI-X crossover, allowing for easy plug-and-play setup without requiring manual configuration.

Another notable characteristic of the TRENDnet TDM-E400 is its versatility in terms of powering options. It supports Power over Ethernet (PoE), which simplifies installation by allowing the device to receive power through the Ethernet cable, eliminating the need for additional power adapters and outlets. This feature is particularly beneficial in environments where power sources may be limited or where the device needs to be mounted in a hard-to-reach area.

In terms of build quality, the TDM-E400 features a compact and rugged design, ensuring durability in various operating conditions. Its intuitive LED indicators provide real-time status updates, making it easy to monitor network status and troubleshoot potential issues.

Additionally, the TDM-E400 is designed to work seamlessly with a range of networking devices, making it an ideal choice for integrating wireless access points, industrial devices, or IP cameras into existing coaxial networks. With its combination of extensive range, ease of use, and robust performance, the TRENDnet TDM-E400 stands out as a reliable solution for businesses and organizations looking to expand their network capabilities with minimal disruption.
