CHAPTER 1 RCI Overview

This chapter gives an overview of the Remote Cabinet Interface (RCI).

1.1 RCI Features

The RCI is a device control interface used for connections of I/O units to an RCI host.

In this manual, a base cabinet and an I/O unit that support the RCI are referred to as an

RCI host and an RCI I/O unit (Note), respectively. Furthermore, RCI hosts and RCI

I/O units are generally referred to as RCI units.

Note: RCI I/O unit might be described as RCI-IO unit.

While multiple RCI units consisting of an RCI host, another RCI host, and RCI I/O

units are connected through the RCI, the RCI controls power supply to all these RCI

units together and performs other controls on the RCI I/O units.

By using RCI cables to connect RCI units and RCI setting commands, the following

RCI functions can be used:

z Connecting and controlling RCI I/O units

z Asynchronous RCI monitoring (Note) of RCI hosts in a cluster environment

Note: Asynchronous RCI monitoring is a function that immediately detects the

panic state in any of the nodes that compose a cluster. The asynchronous

monitoring enables the cluster to quickly recover from a failure in a

monitored node.

Note: When the RCI network is used, adequate consideration of security is

necessary for LAN connections of domains.
