Cable Kit Notes
The cable kit M5000M/RK-1 will work with any Marathon base unit, however if the Marathon
base unit that the Magnum Router is being installed into is a 75e, 3K, 5KT Pro or a 20K Pro;
then it is important that the jumper settings for the A1 port be set for RS-232 operation.
The cable kit M5000M/RK-2 is designed to work only with jumper selectable Marathon base
units (75e, 3K, 5KT Pro, and 20K Pro) as these units allow the A1 port to be changed from RS-
232 operation to V.35 operation. This cable kit will not work on Marathon units 2K, 2K Plus, 5K
Turbo, 10K and 20K.
Verify the Marathon base unit, and jumper position (if necessary) before installing the Magnum
Router.
Installing the Magnum Router Module into the Marathon base unit
Follow these steps to install the hardware.
1. Remove the power cord from the Marathon base unit. Remove the top cover. Remove
all of the necessary “blank” back plane dividers and internal module spacers (found at
the front of each module, nearest the LED’s).
2. Determine which level within the back plane the Magnum Router module is to be
installed. It is recommended that the Magnum Router be installed in the last module slot
or upper-most slot within the Marathon stack.
The Marathon CCM does not recognize the Magnum Router. This means that if
the Magnum is placed in the “B” slot, and the card above it is set for “B”, there will not
be a conflict. However, to eliminate confusion it is recommended that the Magnum
Router be placed in the top most level of the Marathon unit.
3. Install the module in the Marathon chassis like any other Marathon expansion module
paying close attention to the placement of the 2 “50 pin bus connectors” on the right side
of the module. Apply a reasonable amount of pressure over the bus connectors to
ensure the module is properly “seated” then re-install the necessary module spacers at
the front of the module. Using the screws removed from the step 1, fasten the Magnum
Router sheet metal back plane to the Marathon chassis and re-assemble the required
number of blank back plane dividers.
4. Re-install the Marathon base unit top cover and the 4 black screws to hold the top cover
in place.
