2 MIL-140 Media Converters Free

Introduction
The MIL-140 is a multi-mode device that converts optical signals to
electrical signals. The device has a signal capability of transmitting up to 2 km (subject to
fiber budget and collision domain restrictions) and comes equipped with either an SC- or
ST- type connector.
Installation
Do the following to install the MIL-140:
1. Select a well ventilated environment.
2. Attach a UTP cable from the network to the RJ-45 port.
Use screened UTP cabling for CISPR 22 class B installation.
3. Attach both fiber cables TX to RX and RX to TX from the
fiber network cabling to the fiber connectors.
4. Connect the power adapter's cord from the power source to the unit.
MDI-X/MDI Switch
The MDI-X/MDI switch is located on the side of the unit. This switch allows
for quick reconfiguration of the 10BASE-T port.
Cables used when the switch is in the MDI-X position:
• For a hub/repeater, use a swap cable
(pins are connected 1 to 3, 2 to 6, 3 to 1, and 6 to 2)
• For a workstation/PC, use a straight-through cable
(pins are connected 1 to 1, 2 to 2, 3 to 3, and 6 to 6)
Cables used when the switch is in the MDI position:
• For a hub/repeater, use a straight-through cable
(pins are connected 1 to 1, 2 to 2, 3 to 3, and 6 to 6)
• For a workstation/PC port, use a swap cable
(pins are connected 1 to 3, 2 to 6, 3 to 1, and 6 to 2)
Link Sentry Configuration
The Link Sentry feature on the MIL-140 is configured through a 4-position DIP switch
(refer to Table 1).
Link Sentry allows users to add new management tools to the network. When enabled, it
monitors the selected receiver port and, if the LINK test signal is not seen, the unit will stop
sending a signal through the selected transmit port.
Use a mechanical pencil to adjust the DIP switches. The following table shows which Link
Sentry feature is enabled:
Note: Bidirectional link sentry between 2 converters is not supported
Default setting for Link-sentry: All switches set in the UP position (disabled).
