Predefined Configuration File Name
C12_Slave_RIOMainRingFxTx_RIOSubRingTx_DIOCloudsVx.xx.cfg, where
Vx.xx references the version number of the file.
Use of this Predefined Configuration
The most common uses of this predefined configuration are to transition from a copper cable to a fiber cable on the main ring or to transition back from fiber to copper. An alternative use is to provide a long-haul return path for a basically copper network where the last remote I/O drop or remote I/O sub-ring in the daisy chain is far away from the local rack.
In any of the above scenarios, this predefined configuration allows you the opportunity to install a remote I/O sub-ring and/or some distributed I/O clouds on the you are configuring.
With this predefined configuration, use 2 DRSs — one installed with this
slave predefined configuration and the other installed with the corresponding
master predefined configuration (
C11) — to provide a redundant connection between the main ring and a remote I/O sub-ring. The
master DRS passes data between the main ring and the remote I/O sub-ring. If the
master DRS becomes inoperable, the
slave DRS takes control and passes data between the main ring and the remote I/O sub-ring.
NOTE: When a master slave becomes inoperable, a slave DRS assumes the primary role in less than 50 ms. Refer to the Comparison of Master/Slave Configuration and Auto Configuration to determine what roles the master and slave DRSs resume if the master DRS becomes operational again.
NOTE:
DRS inner ports are the 2 ports on the switch that are connected to the main ring. When using 2 DRSs, connect the designated master inner ports to the designated slave inner ports.
-
For copper port master and slave DRS redundant configurations, the inner ports are port 2 for the main ring and port 6 for a sub-ring.
-
For copper/fiber port master and slave DRS redundant configurations, the inner ports are port 3 for the main ring and port 6 for a sub-ring.
If you are using a single DRS but plan to convert to redundant configurations in the future, make a note of these port configurations to minimize any schematic changes required because of the conversion.
Devices Supported and Restricted in this Predefined Configuration
The DRS predefined configuration described here can be used with either of 2 switch types:
-
A TCSESM063F2CU1 ConneXium extended managed switch, which supports multi-mode fiber cable
-
A TCSESM063F2CS1 ConneXium extended managed switch, which supports single-mode fiber cable
Both switches have 2 fiber ports and 6 copper ports.
With single-mode fiber cable, you can achieve distances on the main ring up to 15 km. With multi-mode fiber cable, you can achieve distances up to 2 km.
You cannot use a redundant pair of DRSs to connect a sub-ring to another sub-ring.
Do not connect any devices between the master DRS and the slave DRS on the main ring or the sub-ring. Install the DRSs next to each other — within 100 m.
Predefined Port Connections
The top fiber port (labeled 1 in the figure below) makes the redundant connection to the fiber cable on the main ring (A). The other fiber port (port 2) is disabled in this predefined configuration; do not connect to this port.
The top left copper port (port 3) makes the redundant connection to the copper cable on the main ring (B). Copper ports 5 and 6 are used for the remote I/O sub-ring (C) redundant connections. Ports 4 and 7 are used for distributed I/O cloud connections. 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.

NOTE: When you download this DRS predefined configuration file to a switch, the file provides a set of operating parameters that enable the switch to operate with high efficiency in the specified architecture.
Do not adjust the configuration parameters or alter the port usage from what is shown above. Changing the configuration parameters or the port assignments can compromise the effectiveness and accuracy of the switch and the performance of the remote I/O network.
You can enable/disable port mirroring and change the selection of the source ports that you want mirrored. Port mirroring is disabled by default. The destination port is set to port 8, and ports 1-7 are selected as source ports. Do not change the destination port. When using port mirroring, select the ports, for which you want to analyze the traffic, as the source ports. When you finish troubleshooting, disable port mirroring.
Supporting the Fiber-to-Copper Transition on the Main Ring
Remote I/O devices in the main ring often do not come equipped with fiber connectors. Therefore, some part of the main ring requires copper cable. Typically, 2 DRSs are each configured to support 1 fiber and 1 copper connection to the main ring.
When you use a 140NOC78000 distributed I/O head module, interlink the module with the 140CRP31200 remote I/O head module in the local rack, as shown below:
