This chapter explains the following items regarding the initial build procedure of the
Remote Cabinet Interface (RCI) in the installation work.
-RCI Overview
-RCI command
-RCI Setup
1.1RCI Overview
RCI is an interface to connect RCI Host (general name for main units supporting RCI
and for RCI I/O units).
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, respectively. Furthermore, RCI Hosts and RCI I/O
units are generally referred to as RCI device.
To connect RCI I/O units or to use the RCI asynchronous monitoring functions for an
FJ cluster, a setup using the RCI setup commands is required in addition to the
connection with RCI cables.
1.1.1Overview of RCI connection
There are two types of main unit: midrange servers equipped with one RCI and highend servers equipped with two RCIs.
I/O units include units equipped with one RCI and units equipped with two RCIs.
The following figures show different RCI connection patterns:

1.2RCI command
RCI commands are used to display RCI configuration information and set node
addresses.
To connect I/O units equipped with RCI ports, a setup using RCI commands is
required in addition to the connection with RCI cables.
Remarks: When you use the terminal function of the External power controller,
perform the setrcic command and confirm setting or connection of the
External power controller. For details of the setrcic command, see the RCI
User's Guide or man page.
1.2.1Command list
1.2 RCI command
The RCI commands are explained below.
Table 1.1 Command list
CommandFunction
setrci -c statDisplays RCI configuration information. This command
is used after the RCI setup to verify
that the settings of the host and I/O units have been made
correctly.
setrci -c initInitializes the RCI configuration information.
If other host units are connected through the RCI, the
RCI settings must be initialized on each host unit.
You can use this command if the system is powered off.
setrci -c set [host_no] Sets up an RCI Host node.
Before this command can be executed, the RCI settings
must already have been initialized.
host_noÅF Integer numbers from 1 to 32 are assigned
in this order.
setrci -c initconfigAssigns an RCI address to an I/O unit connected via RCI.
Before this command can be executed, the RCI Host
node settings must already have been made.
setrci -c addconfigMakes the RCI settings for the case that a host unit or an
I/O unit is added.

Appendix A Troubleshooting
A.2In the Case Where RCI Status of RCI Host
Changes From ACTIVE to INACTIVE
Remarks: When this problem has occurred, do not replace the XSCF unit because it
is not a failure of the XSCF unit.
This problem is occurred by the mistake of the RCI construction procedure and the
RCI connection.
t occurrs when the same RCI address is set and constructed, or, when connecting with
the RCI network of the construction of the RCI host that has not been initialized.
Confirm whether to correspond to this problem. The procedure is the following:
1Excute showlogs command, and check whether RCI configuration conflict is
generated in error log.
2When that message was generated, check the RCI establishment procedure,
the RCI address value and the connection.
3In the case of anomaly, correct the RCI address or the connection of relevant
device according to the change procedure of each device.
4Refer to Chapter 1.3.4, "When a RCI Host is added later" and retry RCI
establishment.
