Predefined Configuration File Name
C3_RIOMainRingFX_DIOSubRingTX_DIOCloudsVx.xx.cfg, where
Vx.xx references the version number of the file.
Use of this Predefined Configuration
In some applications, long distances (up to 15 km) may exist between consecutive RIO devices on an M580 network. You can span these distances using single-mode or multi-mode fiber optic cable on the main ring of your network.
The relationship between the main ring and the RIO sub-rings is essentially the same as with
only copper connections, with 2 key differences:
Devices Supported by this Predefined Configuration
The predefined configuration described here can be used with a DRS that supports either single-mode or multi-mode fiber cables.
Both switches have 6 ports that support copper connections. Fiber cable can be used only on the main ring, not on the sub-rings.
With single-mode fiber cable, you can achieve distances up to 15 km on the main ring. With multi-mode fiber cable, you can achieve distances up to 2 km.
Predefined Port Connections
For this predefined configuration, use the 2 fiber ports (ports 1 and 2) for the main ring (A) connections. Use the middle 2 copper ports (ports 5 and 6) to connect an RIO sub-ring (B) to the main ring. The sub-ring can contain only approved RIO modules. No distributed equipment is used in either the main ring or the sub-ring.
Ports 3, 4, and 7 on the DRS are available for additional optional connections, and can be used to connect DIO clouds to the M580 system. Port 8 is reserved for
port mirroring, i.e., for monitoring the status of the ports you previously selected in the switch’s port mirror web page.
NOTE: The default configuration of port 8 has port mirroring disabled.
A
main ring with 2 fiber connections (ports 1 and 2)
B
RIO sub-ring with two copper connections (ports 5 and 6) to some M580 RIO drops

Except when enabling or disabling ports that are not connected to either a main ring or a sub-ring, do not adjust the configuration parameters or alter the port usage in the predefined configuration file. Changing the configuration parameters or the port assignments can compromise the effectiveness and accuracy of the switch, as well as the performance of the RIO network.
Port mirroring is disabled by default. If you enable port mirroring, you can select the ports on which you want to analyze traffic as the source ports. Ports 1-7 can be selected as source ports. Port 8 is the destination port, and it cannot be changed.
Supporting Fiber Links on the Main Ring
RIO devices in the main ring often do not come equipped with fiber connectors. Therefore, some part of the main ring requires copper cable. This predefined configuration is usually implemented with at least 2 other DRSs configured to support
1 fiber and 1 copper connection to the main ring.
In this example, the dashed line represents fiber cable and the solid line represents copper wire:
1
A DRS with a C3 predefined configuration file uses 2 fiber ports that support the main ring and 2 copper ports that support an RIO sub-ring.
2
Two DRS with C5 or C6 predefined configuration files use 1 fiber port to support copper-to-fiber and fiber-to-copper transitions. They enable a fiber-based network to connect to the copper ports on the CPU with Ethernet I/O scanner service in the local rack.
