Installation
There are four LEDs, including:
• TP/ACT: Receiving packets from the 10BASE-T port
Do the following to install the MIL-140 into a rack
mount chassis:
1. Make any configuration changes to the module (i.e.,
DIP switch settings).
• TP/LINK: There is an active connection on the
10BASE-T port
• FX/LINK: There is an active connection on the
2. Remove the screws securing the faceplate and
remove it from the chassis.
10BASE-FL port
• FX/ACT: Receiving packets from the 10BASE-FL port
3. Slide the module into the slot through the guide
rails.

4. Insert the module into the card-edge connector (port
bay). Make sure it is seated firmly.

Pin 1 = Transmit Data +
Pin 2 = Transmit Data -
Pin 3 = Receive Data +
Pin 6 = Receive Data -
5. Secure the module with the two thumbscrews
located on the faceplate of the unit.
The unit is now ready for network connections.
MDI-X/MDI Switch
RJ-45: MDI-X
The MDI-X/ MDI switch allows for quick configuration
of the 10BASE-T port. Cables used when the switch is in
the MDI-X position (the “left” position):
•

•
Pin 1 = Receive Data +
Pin 2 = Receive Data -
Pin 3 = Transmit Data +
Pin 6 = Transmit Data -
•
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)

Link Sentry Configuration
The Link Sentry feature on the MIL-140 is configured
through the 4-position DIP switch (refer to Figure 1).
Default setting for the DIP switches: All switches are in
the “up” position.

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.

Note: For two MIL-140s used back-to-back and UTP-to-UTP, all DIP switches must be enabled (in
the “down” position) on the first MIL-140. On the second MIL-140, enable switches 1 and 4
(in the “down 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)
Default setting for Link Sentry: All switches set in the “up” position (disabled). When using
the SNMP module to control the Link Sentry feature, leave the switches in the default mode
(“up”).
