About this Manual
This document covers the MIL-170TRM media converter module. The terms
“MIL-170,” MIL-170TRM,” and “converter” are used throughout this document
to describe the MIL-170TRM.
Introduction
The MIL-170TRM is one of a series of modules designed to be installed into Digi's
Media Conversion System. This half-/full-duplex device converts optical signals
to electrical and vice-versa.
The device has a signal capability of transmitting up to 15 km (subject to fiber
budget and collision domain restrictions). This module also has the Link Sentry
feature.
Features
• One RJ-45 (UTP) connector
• One single-mode, ST connector
• Link Sentry feature
• Diagnostic LEDs
• Management ready–supplied by the optional SNMP modules (MIL-4650 and
MIL-4655)
• Power supply equipped on the rack mount chassis
Installation
Do the following to install the MIL-170TRM into a redundant rack mount chassis:
1. Make any configuration changes to the module (i.e., DIP switch settings).
2. Remove the screws securing the faceplate and remove it from the chassis.
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.
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
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):
• 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 (the “right” position):
• For a hub/repeater, use a straight-through cable (pins ar e 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-170TRM is configured through a 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.
Model: MIL-170TRM 3
Install Guide
The following table shows which Link Sentry feature is enabled:

Switch Losing Link on RX of Stop sending Link on TX of
1 (down) Fiber port Fiber port
2 (down) UTP port UTP port
3 (down) UTP port Fiber port
4 (down) Fiber port UTP port
Note:
For two MIL-170s used back-to-back and UTP-to-UTP, all DIP switches must be
(in the “down” position) on the first MIL-170. On the second MIL-170, enable switches 1
and 4 (in the “down” position).
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”).
Indicators
There are four LEDs, including:
TP/ACT : Receiving packets from the 10BASE-T port
TP/LINK : There is an active connection on the 10BASE-T port
FX/LINK : There is an active connection on the 10BASE-FL port
FX/ACT : Receiving packets from the 10BASE-FL port
