New Hardware Installation Procedures
The installation of new hardware features onto the 25S/25L/28L/3074 is very similar
to the replacement of existing hardware with a few notable exceptions. First, you
will be removing and discarding existing plates and brackets, and substituting
feature boards in their place. Secondly, you will need to know where to place the
new board, since the existing 25S/25L/28L/3074 does not already have one installed.
Positioning of the new hardware requires knowledge of how the 25S/25L/28L/3074
will react by numbering the cards. Finally, you will probably need to inform the
software that the new hardware has been installed.
