Installation
The module comes equipped with a bank of DIP switches and
jumpers for setting configuration.
The default DIP switch settings (all switches in the UP position)
and jumper settings will work for most installations..
The following steps are used to configure the Perle Fast
Ethernet Media Converter Module:
1. Set the Auto-MDIX jumper (optional).
2. Set the Auto-Config jumper (CM-100 only) (optional)
3. Set the DIP switch settings (optional).
4. Insert the Media Converter Module into the chassis.
5. Connect the fiber cable.
6. Connect the copper cable.
Auto-MDIX Jumper
Note: The factory settings for Auto-MDIX will work for most
installations, but if there is a need to modify the settings, follow
the procedure below.
The AUTO-MDIX jumper (J5) is located on the upper edge, at
the midpoint of the module (see diagram below for labelling). By
covering or strapping pins 1 and 2, the C-100 and CM-100 will
operate as an MDI device. By covering or strapping pins 2 and 3,
the C-100 and CM-100 will automatically detect the Ethernet
cable’s polarity and configure itself as either an MDI or an MDIX
device. Removing the strapping is the same as AUTO.
NOTE: The default jumper setting is Auto

Auto-Config Jumper (CM-100 only)
The Auto-Config jumper (J6) is located just below the Auto-MDIX
jumper (see above). Refer to the diagram below for labelling.
This jumper only applies to CM-100 modules.
Strapping pins 1 and 2 of the jumper will set the module in SW
mode and strapping pins 2 and 3 will set it in Auto Config mode.
Auto: When set to Auto the module will, at power-up, check its
internal flash memory to see if configuration information has
been downloaded to it from a management module. If so it will
use this as its running configuration. If there is no configuration
in flash it will read the settings of the DIP switches and use those
as its running configuration.
SW: When set to SW (Switch), the module will, at power-up,
read the settings of the DIP Switches and use those as it running
configuration. It will ignore any configuration information in its
flash memory.
NOTE: The default jumper setting is Auto

Auto
Off
Auto: In this mode of operation the Media Converter Module will
negotiate Ethernet parameters on the copper connection. This will
ensure the most optimal connection parameters will be in effect. If the
copper link partner does not support Auto negotiation, the C-100 and
CM-100 will default to 100 Mbps and Half Duplex mode.
Off: Auto Negotiation should only be turned off, if the copper link
partner does not support Auto Negotiation.
When the Auto Negotiation switch is set to the OFF position, the
Media Converter Module will operate at 100 Mbps and Full Duplex
mode.

Link Mode (Switch 2)
Switch
Mode
Position
Up (default)
Link Pass-Through Mode
Standard Mode
Down
Link Pass-Through: In this mode, the link state on one connection is
directly reflected through the Media Converter Module to the other
connection. If link is lost on one of the connections, then the other link
will be brought down.
With Media Converters on both ends of the fiber link and both setup
for Link Pass-Through, then a loss of copper link on the far end
device will propagate through both Converters and will result in a loss
of copper link at the near end device. This would, in effect, resemble
a direct copper connection.
Standard Mode: In this mode, the links on the fiber and copper sides
can be brought up and down independently of each other. A loss of
link on either the fiber or copper port can occur without affecting the
other connection.
Far End Fault (Switch 3)
Switch
Mode
Position
Up (default)
Down
Enabled
Disabled
Enabled: If the Media Converter Module detects a loss of fiber signal
on the fiber receiver, it will immediately send a FEF on the fiber link.
This, in effect, notifies the fiber link partner that an error condition
exists on the fiber connection.
If the remote Media Converter is set up for Far End Fault (FEF) and
the local Media Converter is set up with Link Pass-Through, a loss of
fiber link on either the transmit or receive line will be passed through
to the local copper connection thus notifying the connected device.
Fast Ethernet Media Converter – Installation Guide
6
If the Media Converter has been set to Link Pass-Through mode, the
effect will be the same as FEF, since the link loss on the fiber receiver
will bring down the copper link, which will in turn cause the transmit
fiber link to be brought down.
Note: If it is required to either generate or detect the FEF signal, then
the FEF switch needs to be set.
Disabled: The Media Converter Module will not monitor for, or
generate Far End Fault.
The following diagram is an illustration of the operation of this feature.
(A) – Remote Media Converter setup for Far End Fault Enabled, Auto
Negotiation – OFF and Link Mode – Standard.
(B) – Local Media Converter setup for Link Pass-Through - Enabled
and Auto Negotiation - OFF
1 – (A) loses fiber connection on its receiver
2 – (A) sends an FEF
3 – (B) detects loss of link in its fiber receiver
4 – (B) drops link on copper connection through Link Pass-Through
5 – (A) Link on copper connection is not affected.

Disabled
Enabled: When Auto Negotiation has been set to Auto (SW 1), the
Media Converter Module will use this setting for its Ethernet
parameter negotiation on the copper connection.
Disable: The Media Converter Module will not negotiate support for
the Pause feature.
Note: The Media Converter Module will not act on, or generate any
Ethernet Pause messages, but will pass them through to the end
device. This switch setting is provided so that the attached device
(near end) can negotiate its Ethernet parameters as if it was
negotiating directly with the far end device. The Pause switch setting
on the Media Converter Module should match the capabilities of the
far end device.
Loopback (Switch 6)
Switch

Disabled
Enabled
Disabled: This is the normal position for regular operation. The switch
must be set to this position in order for data to pass through the
Media Converter Module.
Enabled: This is a test mode. All data received on the receive (RX)
fiber connection is looped back to the transmit (TX) fiber connection.
The state of the copper is not relevant and no data or link status is
passed through to the copper side.

Installing or Replacing Media Converter
Modules
Caution: Observe electrostatic discharge precautions when
installing the Media Converter Module(s) into the Chassis.
Failure to observe this caution could result in damage to the
Module(s) and/or chassis.
The Perle Media Converter Modules can be installed in any available
slot and in any order within the MCR Chassis.
Installing or Replacing a Media Converter Module
1. Remove the Media Converter Module from its packaging.
2. Using a cross-head screwdriver, remove the screw holding
the face plate to the Chassis to reveal the slot opening.
3. Set the jumpers and DIP switches on the Media Converter
Module to the desired operating mode.
4. Locate the top and bottom alignment guides inside the
MCR Chassis.
5. Using the module alignment guides gently slide the module
into the slot until it becomes flush with the front of the
Chassis. Light pressure may be needed to seat the module.
Do not force the module as you might cause damage. If
there is resistance, remove the module and check the
module connector for damaged or incorrectly aligned pins.
If these are not damaged, retry module insertion.
6. Tighten the captive retainer screw to ensure the Media
Converter Module is locked in place.

7. Remove the dust cap from the fiber connector and connect
the fiber and copper cables.
Removing Media Convert Modules
1. Loosen the captive retainer screw on the front of the Media
Converter Module and gently pull the module out.
2. If not inserting a replacement Media Converter Module,
cover the opened slot with a face plate and secure the
screw.
Installing the Duplex Fiber Cable
Locate a 100Base-X compliant duplex (2 strands) fiber cable
with the appropriate connectors.
Connect the fiber cables from the Media Converter Module to the
other Media Converter/switch/fiber device ensuring that the RX
and TX are reversed at the opposite end.
Fast Ethernet Media Converter – Installation Guide 10
Installing the Simplex Fiber Cable
•
•
Locate a 100Base-X compliant simplex (1 strand) fiber cable
with appropriate connectors.
Connect the fiber cable from one Media Converter Module to
another Media Converter/switch/fiber device.
Installing the Copper Cable
•
Locate 100Base-TX compliant copper cables with male, RJ-
45 connectors installed at both ends.
•
Connect the RJ-45 cable between the Perle Media
Converter Module and the device.
Note: The Perle Media Converter Module supports Auto-MDIX,
therefore a straight-through or cross over Ethernet cable may be
used.
Fast Ethernet Media Converter – Installation Guide 11
Operation
Status LED
The Perle Fast Ethernet Media Converter modules have three
single color status LEDs located on the face plate of the module.

•Blinking quickly: the module has a hardware error.
LKF - Fiber Link/Activity
•On: Fiber link present.
•Blinking quickly: Fiber link present and receiving data.
•Off: No fiber link present.
LKC - Copper Link/Activity
•On: Copper link is present.
•Blinking quickly: Copper link present and receiving data.
•Off: No copper link present.
Fast Ethernet Media Converter – Installation Guide 12
Other Features
Auto-MDIX:
Auto-MDIX (automatic medium-dependant interface) detects the
signalling on the 100BASE-T interface to determine the type of
cable connected (straight-through or crossover) and
automatically configures the connection.
Error Recovery:
In certain configurations, and under specific conditions where the
Media Converter Module brings down a link to convey status,
there is potential for a deadlock. Recovery is achieved by
momentarily restoring the link to see if the original failure has
been resolved. If it has not, the link will be forced down again,
however if the original problem has been resolved, the link will
be restored.
Fast Ethernet Media Converter – Installation Guide 13
Troubleshooting
General
•
Ensure the module is correctly seated to the backplane in the
MCR Chassis. The PWR LED should be on solid.
Ensure both devices on either end of the fiber are
compatible. If using a simplex fiber connection, ensure that
you have both an Upstream (U) and Downstream (D) Media
Converter.
•
•
•
Ensure all cabling is of the correct type and is in good
working order.
For duplex fiber connections, ensure the RX and TX has
been reversed between the two Media Converters.
No connectivity
If unable to get full connectivity with all DIP switches in the UP
position, these methods are recommended for troubleshooting.
Method 1
1. If the Module is a CM-100, set the Auto-Config jumper (J6)
to SW so that switches are being read.
2. Set the Link mode to Standard (SW2 – Down) on both
Media Converters. Leave all other switches in the Up
position.
3. Connect the near end device to the copper connection. The
LKC LED indicates good copper connection. If the LKC LED
is not lit, then check the copper cable and the attached
device. Repeat for the far end Media Converter.
4. Connect the fiber cable to both converters. The LKF LED
indicates good fiber connection. If no LKF LED then check
the fiber cabling.
5. Return Media Converter to the desired configuration.
Fast Ethernet Media Converter – Installation Guide 14
Method 2:
The fiber connection can also be verified by configuring the
remote Media Converter for loopback mode. The LKF LEDs on
both Media Converters should be lit. Data should pass through
the local converter, over the fiber connection to the remote
Media Converter. At the remote Media Converter, the data will
be looped back and passed through the fiber, once again, to
pass through the local converter to the copper link.
Note: If troubleshooting a CM-100, setting the Auto-Config
jumper (J6) to SW will ensure the DIP switches are being read.
