Many of the Advant Controller 450 components are installed in subracks. Subracks are fitted
with guide bars for circuit boards and other plug-in units. Each unit is connected to the
backplane of the subrack. There are two variants of subracks, both based on a 19-inch standard:
a controller subrack which houses the processor module and the various communication
modules and an I/O subrack which houses the S100 I/O.
&RQWUROOHU6XEUDFN
This subrack exists in one standard height, 400 mm, which includes a cable duct and fan unit.
The disposition of slots is shown in Figure 1-52.
All modules are individually fixed to the subrack with a locking device.
All connections are made from the front.

The controller subrack cannot accommodate any I/O boards. If S100 I/O is desirable, you must
expand the system with one to five I/O subracks.
An I/O subrack can contain up to 20 (19 in case of S100 I/O Bus Extension redundancy) I/O
boards plus one or two bus extension boards which has both voltage supervision and bus-
extension functions. An I/O subrack is connected to the controller subrack and to the next I/O
subrack via the bus extension board, position 21 (20 and 21 in case of S100 I/O Bust Extension
redundancy).
