networks:
1. Ensure the Coupler and Control cables are disconnected at this point.
2. Get Both N-Rings working with a status of OK.

Port. Save Configuration.
4. Configure N-Link Master: Select the Control and Coupler ports. Save the Configuration.

Configuration
Requirements:
•
The Master and Slave must be part of the N-Ring topology.
•
If using default configuration choices, the administrator only needs to configure the N-Link Master. The
N-Link Slave and both Coupler switches will auto-detect any needed configuration.
•
If not using default configuration choices, the administrator may also need to configure the Default Coupler
port on the N-Link Slave.
•
There must be a direct link between the Master and Slave Control ports. Use of media converters or other
switches is not supported.
•
There must be a direct link between the Master and Slave Partner ports. Use of media converters or other
switches is not supported.
•
There must be an N-Link aware switch on each side of the Master.
•
N-Link will only support a single point of failure. Multiple points of failure and misconfiguration are not
supported and may cause a network storm under some circumstances.
•
Control and Partner connections should be either fiber or 10/100Base-TX copper.
