1. General
The CPR consists of the following components.
(a) CPU BOARD: Contains the Main Processor Unit (MPU), ROM, and 128 Mbyte of Random Access 
Memory (RAM). Additionally, this board may be equipped with the ISAGT (PZ-
GT13) on its Industrial Standard Architecture (ISA) bus, and LANI (PZ-PC19) on 
the Peripheral Component Interconnect (PCI).
(b) DSP: Contains the CPR switches and the CPR status indicator...

2. Mounting Location/Condition
The CPR is composed of the CPU BOARD, DSP, FDD/HDD, and PWR and is located in the Local
Processor Module (LPM) as shown below. Since the CPR provides the Industrial Standard Architecture
(ISA) bus and Peripheral Component Interconnect (PCI) bus, the GT and LANI cards are located in those
busses respectively.
