Install the TDM Module
1.
Grasp the module by its edges. Orient it towards the plug and the rear panel of the
chassis as you found the original module.
2.
Push the right side of the module into the chassis rear panel slot, and, at the same
time, slide the left side of the piece of metal into the rear panel.
3.
Push the module laterally into the plug and toward the rear panel of the chassis.
You may have to work the module back and forth as you pull, in order to secure
the module from the two directions.
Note that there is a gap in the edge connector of the module PCB. There are
metal bands on either side of the gap. The left-most part of the connector section
is outside of the plug.
4.
Attach the screw that secures the piece of metal attached to the module to the rear
panel.
5.
After you finish installing the module, replace the cover of the unit.
