Racks
Section 2-2
2-2 Racks
This section describes the Racks used to construct a PC System. The individual
components used to construct the Racks are described in the next section.
2-2-1 CPU Racks
The following figure shows the parts of the CPU Rack. There are five Back-
planes available for the CPU Rack. Any CPU can be mounted to any Backplane.
The only differences in the Backplanes is the number of slots that they provide
for Units, their expansion capability, and the number of slots for CPU Bus Units.
The CV500-BC031, CV500-BC051, and CV500-BC101 provide complete ex-
pansion capability and provide 3, 5, and 10 slots, respectively, for Units other
than the CPU, Power Supply Unit, and I/O Control Unit.
The CVM1-BC053 and CVM1-BC103 do not support I/O Control Units and pro
-
vide 5 and 10 slots, respectively, for Units other than the CPU and Power Supply
Unit. Because I/O Control Units are not supported, these Backplanes can be
connected only to a single Expansion I/O Rack as illustrated on page 18.The
CPU Backplane cannot be used for an Expansion CPU or Expansion I/O Rack.

Units, SYSMAC LINK Units, SYSMAC BUS/2 Masters,

C500 Special I/O Units, SYSMAC BUS Masters)
An I/O Control Unit must be mounted to the Rack in order to
connect an Expansion CPU or more than one Expansion I/O
Rack. The model of I/O Control Unit used determines the
other Racks can be connected.
