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

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.

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)

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.  
Fast Ethernet Media Converter – Installation Guide

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.  
PWR - Power/Test

Blinking slowly: the module is in loopback mode.  
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.
