Naming Ports and Nodes for Serial Targets with Direct Port Access

When using direct port access to serial targets of Dominion SX, combined with accessing ports on the SX without using CC-SG, it is recommended that the port name and the node name for the target are identical.

If the port name and the node name are not the same, you will need to know both names, and use the correct name depending on your point of access. For example, depending on whether you access via CC-SG, or directly via SX.

CC-SG enforces unique node names. Make all changes in CC-SG using these procedures to ensure a unique name is propagated to the port, to keep names in synch, and to prevent connections from going to the wrong target.

• To name ports and nodes for serial targets with direct port access:

1. When configuring SX ports on CC-SG, set the node name and the port name to be the same. The port name propagates to the SX.
2. Configure only 1 serial interface per CC-SG node. This results in unique names for nodes that are identical to the port name.
3. When changing a CC-SG node name, change the port name to be the same to keep the SX port name and its associated node in synch. The new port name propagates to the SX.
