Redundant Enable Jumper

 

Jumper JP1 is used to set the port to operate in the redundant port 
mode. The 10BASE-FL RDN Media Adapter is shipped with the 
redundant port mode set to off.

To set the port to operate in the redundant port mode, perform the 
following steps:

•

Locate the shunt covering the JP1 jumper pins on the media 
adapter board.

•

Gently remove the shunt from the two far left pins.

•

Replace the shunt over the two far right pins.

 

NOTE: 

 

Jumpers JP2, JP3, and JP4 are not 

user-configurable.
