Loopback (Switch 7)
Switch Position Mode
Up (default) Disabled
Down Enabled
Disabled: This is the setting for normal 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 link is not relevant since no
data is passed through to the copper side. This mode will override
all other switch settings.

Caution: Observe electrostatic discharge precautions when
installing the Media Converter Module(s) into the Chassis. Failure

The Perle Media Converter Modules can be installed in any
available slot and in any order within the chassis.
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
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 some damage. If there is
resistance, remove the module, check the module connector
for damaged or incorrectly aligned pins, if there is no damage,
retry to insert the module.
