Section 5

Configuring the Input/Output Module

Introduction

This section explains how to configure the I/O module (IOM) and its components.

It covers that portion of the Input/Output system considered part of the central system; that is, from the IOB for the NX5820 or the KIUB for the NX5820 K to the Common Input/Output Module (CIOM) and including the channel interface.

It does not cover from the channel interface outward. That information is included in the Unisys e-@ction ClearPath Enterprise Servers A Series and NX Systems I/O Configuration Guide (7008 6087). See "Information Contained in the I/O Configuration Guide" at the end of this section for a list of topics.
