Fast Ethernet Media Converter

FCC Compliance Statement

This equipment generates and uses radio frequency energy. If not installed and used properly, in strict accordance with the instructions provided, it may cause interference to radio and TV reception. The equipment has been tested and found to comply with the limits for a Class A computing device, in accordance with specifications in Subpart B of Part 15 of FCC rules. These rules are designed to provide reasonable protection against such interference in a commercial environment. However, there is no guarantee that interference will not occur in a particular installation.

If you suspect this equipment is causing interference, turn your converter on and off while your radio or TV is showing interference to determine the source. You can try to correct interference by:

• Reorienting the receiving radio or TV antenna where this may be done safely.

5. Installation

Operating Environment

This converter must be installed and operated within the specified operating temperature and humidity limits (refer to the Specifications section). Do not place objects on top of the unit. Avoid positioning the converter near heating sources such as heaters or radiators, or in direct sunlight. Prevent water and moisture from entering the unit. Use a dehumidifier if necessary to reduce humidity.

Guidelines for Installation

• The nodes connected to the media converter must operate at 100Mbps.
• The two nodes connected to the ports of the media converter must operate with the same duplex mode.
• Devices connected to the media converter can include network adapters, hubs, switches, or routers.
• The network configuration with the media converter can follow various architectures.

Network Configuration Diagrams:

Standalone Configuration: Illustrates two network switches connected by a media converter. The UTP connection spans 100 meters, and the fiber optic connection spans 2 Kilometers (100Mbps fiber).

Back-to-Back Configuration: Shows two network switches and a PC interconnected via media converters. One UTP connection is 100 meters. One fiber optic connection spans 60 Kilometers (100Mbps fiber), and another UTP connection is 100 meters.

Connecting the Cable

Ensure UTP and fiber cables are properly connected to the converter. Use a Category 5 UTP straight-through cable for connecting the UTP normal port to a PC/adapter or the UTP uplink port to a hub port. For fiber connections, use 50/125 or 62.5/125 micron multi-mode fiber for multi-mode media converters, and 9/125 micron single-mode fiber for single-mode media converters.

Connecting the Power

Connect the output end of the power adapter to the power connector on the rear panel of the converter. Plug the power adapter into a power outlet. The green Power LED on the front panel should illuminate.

6. Trouble-shooting

UTP or Fiber Link LED is not lit

• Check the power switch on the network device connected to the converter; ensure it is turned ON.
• Verify the network cable: ensure the UTP cable complies with EIA/TIA 568 specifications and fiber optic cables comply with industry standards.

Fail to transmit data

• Ensure the UTP distance does not exceed 100 meters.
• If the FDX LED is not lit (indicating operation at half-duplex mode), confirm the fiber distance does not exceed the maximum distance listed below. If the FDX LED is lit (full-duplex mode), the fiber distance should not exceed the converter's available maximum distance (e.g., 2km or 60Km).
