Fast Ethernet Fiber to Fiber Media Module – Installation Guide 4
Installation
The media 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 Media
Converter Module:
•Set the Auto-Config jumper. (CM-100MM only) (optional)
•Set the DIP switch settings. (optional).
•Insert the media module into the chassis.
•Connect fiber cable 1 to port MM1.
•Connect fiber cable 2 to port MM2/SM2.
Auto-Config Jumper (CM-100MM only)
The Auto-Config jumper is J5.
Refer to the diagram below for labelling. This jumper only applies
to the CM-100MM converter module.
Auto (Pin 2 and Pin 3 are strapped): When set to Auto. At power
up the media module will, check its internal flash memory to see if
configuration information has been downloaded to it from a
management module. If so, the media module will use this
configuration as its running configuration. If there is no
configuration in flash, the media module will read the settings of
the DIP switches and use those settings as its running
configuration.
SW (Pin 1 and Pin 2 are strapped): When set to SW (Switch). At
power up, the media module will read the settings of the DIP
switches and use those settings as its running configuration. The
media module will ignore any configuration information in its flash
memory.
Note: The default jumper setting is Auto

DIP Switch Settings
Note: All switch changes take effect immediately and will result in
a link reset on both fiber ports.
Link Mode (Switch 1)
Switch
Position Mode
Up (default) Link Pass-Through Mode
Down Standard Mode
Link Pass-Through: In this mode, the link state on one fiber
connection is directly reflected through the media module to the
other fiber connection.
Standard Mode: In this mode, each fiber link can be brought up
and down independently of each other. A loss of link on either fiber
connection can occur without affecting the other fiber connection.

Fast Ethernet Fiber to Fiber Media Module – Installation Guide 6
Far End Fault (Switch 2)
Switch
Position Mode
Up (default) Enabled
Down Disabled
Enabled: If the media module detects a loss of fiber signal on the
fiber receiver, the media module will immediately send a FEF on
the transmitter of its fiber link to the remote end module. This, in
effect, notifies the fiber link partner that an error condition exists on
the fiber connection.
Note: This switch needs to be set to either generate or detect the
Far-End Fault signal.
Disabled: The media module will not monitor for, or generate Far
End Fault.

Installing Media Converter Modules
Caution: Observe electrostatic discharge precautions when
installing the media module(s) into the chassis. Failure to observe
this caution could result in damage to the module(s) and/or
chassis.
The Perle media module can be installed in any available slot and
in any order within the MCR chassis.
•Remove the media module from its packaging.
•Using a cross-head screwdriver, remove the screw holding the
face plate to the chassis to reveal the slot opening.
•Set the jumpers and DIP switches on the media module to the
desired operating mode. (optional)
•Locate the top and bottom alignment guides inside the MCR
chassis.
•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 to insert the module.
•Tighten the captive retainer screw to ensure the media module
is locked in place.
•Remove the dust caps from the fiber connectors and connect
the fiber cables.

Fast Ethernet Fiber to Fiber Media Module – Installation Guide 9
Removing Media Convert Modules
Loosen the captive retainer screw on the front of the media
module and gently pull the module towards you.
If not inserting a replacement media 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 module to the other
media module/switch/fiber device ensuring that the RX and TX are
reversed at the opposite end.
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 module to another media
module/converter/switch/fiber device.

•On- Fiber link present.
•Blinking- quickly: Fiber link present and receiving data.
•Off- No fiber link present

Fast Ethernet Fiber to Fiber Media Module – Installation Guide 11
Troubleshooting
General
•Ensure the module is correctly seated to the backplane in the
MCR chassis. The PWR LED should be on solid.
•Ensure all cabling is of the correct type and is in good working
order.
•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 module.
•For duplex fiber connections, ensure the RX and TX has been
reversed between the two media converter module.
No connectivity
If unable to get full connectivity with all DIP switches in the UP
position, these methods are recommended for troubleshooting.
Note: If troubleshooting a CM-100, setting the Auto-Config jumper
(J5) to SW will ensure the DIP switches are being read.
Method 1
1. Set the Link mode to Standard (SW1 – Down) on both media
converter module. Leave all other switches in the Up position.
2. Connect the near end device to the MM1 port. The LK1 should
be lit to indicate a good fiber connection. If the LK1 LED is not
lit, then check the fiber cable and the attached device.
3. Repeat step 2 for the MM2/SM2 port
4. Return the media module to the desired configuration.
Method 2:
The fiber connection can also be verified by configuring the remote
media module for loopback mode. The LEDs on both media
converter module should be lit. Data should pass through the local
module, over the fiber connection to the remote media module. At
the remote media module, the data will be looped back and
passed through MM2/SM2 transmit fiber link.
