Special Precautions

With the FP2
The FP2 uses the term "module" when express the size of the unit or backplane.
The unit installation sizes come in two sizes: the basic 1-module size, and the 2-module
size that is twice as wide.
The 1-module unit is the size that physically takes up the space of one guide on the
backplane.
The 2-module unit is the size that physically takes up the space of two guides on the
backplane.

Backplane Selection
Following two kinds of backplanes are available.
1) FP2 backplane (AFP25***) (Color of letters on the printed board: White)
2) FP2 backplane H type (AFP25****H) (Color of letters on the printed board: Yellow)
These two backplanes cannot be used in combination.
Carefully select the type of backplanes before you order.
The selection of the backplane should be based on the total number of modules to be
used in the system. In other words, the module number of the backplane must be
greater than or equal to the total number of modules for the system. So be sure to select
a backplane that allows the installation of all the required units.
