CHAPTER 13 RCI Setting
13.1 Overview
The remote cabinet interface (RCI) function turns on/off the power of the expansion unit along with the main unit.
The RCI function also reports any error that occurring in an expansion unit to the main unit.
RCI displays the current node addresses, executes initialization, and requests the binding of a new node after hot
system replacement. It supports the commands explained below.
13.2 RCI Commands
Overview The RCI command has a function that displays the RCI configuration information, sets the node
address, and incorporates the node during hot system replacement.
The following table lists the RCI commands:
rci-config This command displays RCI configuration information. Use
this command to check the host node address and references
node device names after the RCI setting.
rci-config n m This command initializes RCI and sets an address for the
local host node. It does not connect the node. N is the
node address number and m is the number of hosts (n=m).
(Necessary command for initialization)
rci-configio-init This command sets new addresses of all RCI nodes (host and
I/O) and connects them. I/O node addresses are reassigned,
starting with 1. Use this command in initial installation.
rci-configio Use this command to add or remove a local node (I/O).
Notes
In initial installation, execute an rci-config command by specifying n=1 and
m=1. Then, execute an rci-configio-init command.
When adding a host node, set the mode switch on the panel of a connected host
node to "MANUAL." This masks a failure report caused by the node expansion.
Then, use the RCI cable to connect the expansion target host and turn on the host.
Execute an rci-config n m command and an rci-configio command in
the host. Set the mode switch to the original position when the connection is
complete.
When adding an I/O node, set the mode switch on the panel of a connected host
node to "MANUAL." Use the RCI cable to connect the expansion target host and
turn on the host again. Then, execute an rci-configio command when the
ok prompt is displayed.
