Kernel Power Supply Module (A1)
Each Kernel Power Supply module receives 24 Vdc from the main power
supplies and provides regulated 5 Vdc and 5 V pre-charge power sources to the
other kernel modules (CPU and I/O modules). The 5 Vdc power source is used
by each module in the kernel section to power its microprocessor. The 5 V pre-
charge power supply is only used as a pre-charge power source to allow all I/O
modules to be hot replaceable. The 24 Vdc power from the main power supplies
is routed through this module to the other kernel modules to allow all kernel
power to be completely removed when this module is not installed. This module’s
health and operation is monitored and verified by its respective kernel CPU.

Central Processor Unit (CPU) Module (A2)
This module, following the instructions of the application program, controls the
circuits of the 5009 control so that they perform all the required control and
sequencing functions. There are three CPU modules provided with each system.
Figure 2-3 is a diagram of a 5009 CPU module. Each CPU utilizes a Motorola
68040 microprocessor to perform its data processing. The VME bus arbitrator
block controls the VME bus and determines what device may use the bus when
there is a conflict.
An RS-232 Serial Port is located on the front of each CPU to interface with the
PCI engineering workstation, OpView or other RS-232 compatible devices.
The CPU has a PCMCIA (Personal Computer Memory Card International
Association) slot on its front panel. The PCMCIA slot is used to down load
application files to the CPU module.
