Installation  
The default switch settings (all switches in the UP position) will  
work for most installations. See the Operation section of this guide  
for more details.  
The module comes equipped with a bank of DIP switches and a  
set of jumpers for setting configuration.  
The following steps are used to configure the Media Converter  
module.  
1. Set the Auto-Config jumper. (CM models only) (optional).  
2. Set the DIP switch settings (optional).  
3. Insert SFP modules into the transceiver ports.  
4. Insert the module into the chassis.  
Auto-Config Jumper (CM only)  
The Auto-Config jumper is J5. Refer to the diagram below for  
labelling.  
Auto (Pin 2 and Pin 3 are strapped): 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: (Pin 1 and Pin 2 are strapped): 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

Smart Link Pass-Through Mode  
Standard Mode  
Smart Link Pass-Through: In this mode, the fiber link state on  
one fiber connection is directly reflected through the Media  
Converter module to the other fiber connection. Since this media  
converter module is protocol independent, it monitors the Signal  
Detect indicator from the SFP and reflects this on the TX port of  
the other SFP by turning off the transmitter. When the signal (Link)  
gets restored and Signal Detect becomes active the affected  
transmitter will get re-enabled.  
Standard Mode: In Standard Mode the media converter module  
will monitor the fiber link in the same manner. If Signal Detect  
goes down the media converter module will output a 25MHz signal  
on the TX port of the other SFP.

Fiber Fault Alert (Switch 2)  
Switch Position Mode  
Up (default)  
Down  
Enabled  
Disabled  
Enabled: If the media converter module detects a loss of fiber  
signal on its fiber receiver, it will disable its fiber transmitter on the  
same SFP. This, in effect, notifies the fiber link partner that an  
error condition exists on the fiber connection.  
Disabled: The Protocol Transparent Media Converter module will  
not monitor for Fiber Fault.  
Note: If 2 media converters are connected to each other, FFA  
should not be enabled on both since this could create a “dead-  
lock” state.

High Speed  
Low Speed  
High Speed – When a multi-rated SFP is inserted, it is enabled for  
its higher speed of operation.  
Low Speed – When a multi-rated SFP is inserted, it is enabled for  
its slower speed of operation.

Installing Protocol Transparent Media  
Converter Modules  
Caution: Observe electrostatic discharge precautions when  
installing the Protocol Transparent Media Converter module(s) into  
the chassis. Failure to observe this caution could result in damage  
to the module(s) and/or chassis.  
The Protocol Transparent Media Converter module(s) can be  
installed in any available slot and in any order within the MCR1900  
chassis.  
1. Remove the 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 jumper and DIP switches on the module to the  
desired operating mode. (optional)  
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 module is  
locked in place.  
7. Remove the dust cap from the fiber connectors.

Removing Media Convert Modules  
1. Loosen the captive retainer screw on the front of the Protocol  
Transparent Media Converter Module and gently pull the  
module out.  
2. If not inserting a replacement Protocol Transparent Media  
Converter Module then cover the opening slot with a face  
plate and secure the screw.

Operation  
Status LED  
The Media Converter modules have three status LEDs located on  
the face plate of the module.  
PWR  
On – Power On  
Blinking Fast – Hardware Error  
LK1  
On – Signal Detected  
Off – No Signal Detected  
LK2  
On – Signal Detected  
Off – No Signal Detected  
Troubleshooting  
General  
Ensure the module is securely seated in the chassis. The  
PWR LED on the module should be On solid.  
Ensure all cabling is of the correct type and is in good  
operating condition.  
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) SFP module inserted and a Downstream (D)  
SFP module inserted.
