Part# 5500335-10
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

DIP Switch Settings
Link Mode (Switch 1)
Switch Position Mode
Up (default)
Down
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.
5
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.
Rate Select (Switch 3)
Switch Position Mode
Up (default)
Down
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.
7
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.
