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

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.
