1.2 Configuration of Main Unit

There are two types of basic base units for the L3 controller: one for single configuration
and the other for duplex configuration.
The L3 main unit (basic unit) comprises an L3 CPU module which is the core component
of the L3 controller, an EN7 module for connection to the Ethernet, various other IF
modules, and a power supply module which supplies power to each of these modules.
Each module is installed in each slot of the basic base unit.
1.2.1

Single Configuration

The basic base unit is available in four types which differ in the number of slots for
connection with station bus: 2-slot, 4-slot, 6-slot and 8-slot types. The power supply
module is installed in slot [PS], the L3 CPU module, EN7 module, and IF modules in the
station-bus-connectable slots ([S1] through [S*]: * represents number 1, 3, 5 or 7), and
G3 I/O modules in slots for connection with direct bus ([S#] through [S10]: # represents
number 2, 4, 6 or 8).
Figure 1-3 shows an example of basic unit in single configuration (BU748).
