Modular CPU Baseplates (Figures 3-4 and 3-5)
Ŷ
A Power Supply module must be plugged into the left slot (which is not numbered) of these
baseplates. The left slot is a unique size and type that only supports a Power Supply module.
Ŷ
A CPU module (or a special Option module) must be installed in Slot 1 of these baseplates.
Slot 1 is a unique size and type that only supports a CPU module or a special Option module
like the FIP Remote I/O Scanner (IC693BEM330). Slot 1 is labeled CPU/1.
Ŷ
Slots numbered 2 and above are of a unique size and type that only supports I/O or Option
modules.
Ŷ
Expansion and Remote baseplates are supported, so a 25-pin D-type female expansion
connector is located at the right end of the baseplate for connecting to an Expansion or Remote
baseplate.
Ŷ
Since the CPU is modular, it can be replaced or changed to a different type if additional
features are desired.
Ŷ
Only one CPU baseplate is allowed per system. If more than one baseplate is used in a system,
the additional ones must be either Expansion or Remote types.
Ŷ
A modular CPU baseplate is always assigned, by default, Rack Number 0.
