Installing the Intelligent Media Converter Modules
• The LE7501A Management Module can only be installed in the far
right-hand slot. See diagram.
• Intelligent “redundant twister”
™
modules have DIP switches that must
be set prior to installation. Refer to the
Intelligent Media Converter
“redundant twister” Module Installation & User Guide
for more details.
• Intelligent “redundant twister” F/O modules require two slots.
• Modules must be firmly secured to the chassis before network
connections are made.
Follow the simple steps outlined below:
1. Grasp a module by the front panel as shown and insert into a slot
making sure that both the top and bottom of the card edges are lined
up with the top and bottom card guides.
2. Slide the module in until the top and bottom edges of the front panel
are flush and even with the top and bottom edges of the chassis and
secure to the chassis by turning the thumb screw clockwise until snug.
