Quantum Local I/O, Remote I/O and Distributed I/O Configurations

Overview

The following information contains a description of the Local I/O, Remote I/O and

Distributed I/O and their configurations.

These configurations (see the configuration table below for valid Quantum

configurations) can be equipped with a combination of:

z Quantum CPUs

z Power supplies

z I/O interfaces

z Expert modules

z I/O modules

NOTE: Refer to System Specifications for the Quantum Module, page 53 for a

complete list of part numbers for all Quantum modules.

Local, RIO, and DIO Configuration

The following table provides valid Quantum configurations, including backplanes

and modules.

NOTE: Every Quantum module requires power from the backplane (except power

supply and DIO modules). For a valid configuration, add up the required backplane

current (in mA) for every module, and ensure that this number is less than the

available power in the selected power supply.
