Output Expansion
Similarly, LD-33100 Loader boards may also be used for output-
expandable systems. For example, Figure 28 shows a 512 x 512 system
expandable to 512 x 1024:
Figure 28.
Again, considering one signal path (Figure 29), pre-wired cable connec-
tions do not allow for installation of individual terminators. Instead,
LD-33100 Loader boards are installed in the unused frame, but in this
case they are installed in the input slots.

Input and Output Expansion
The rules just described for use of LD-33100 Loader boards will also
apply to systems designed for expansion of both inputs and outputs.
An example would be a 512 x 512 pre-wired for expansion to 1024 x
1024 (similar to the system shown on page 52). Only chassis 0 would be
active in the 512 x 512 router, so only the port expanders connected to
Frame 0 would be in use. Frame 1’s inputs are connected to the top left
PE; while Frame 2’s outputs are connected to the top right PE. Therefore
Frame 1’s input slots would require LD-33100s and Frame 2’s output
slots would require LD-33100s. No LDs would be needed for Frame 3.
