Performing EXNET-ONE Card Diagnostics will take the EXNET Ring out of service. *The External Loop Back mode can be used when both I/O ports are externally looped back with fiber optic cabling.
	0x05 Prepare For Addition There is no data associated with this entity. 0x06 Expand Ring There is no data associated with this entity. 0x07 Loop Back Port Node ID of the neighbor CSP node. This message must be sent to the node that will loopback its "A" port. The neighbor node will automatically loopback "B" port. Data[0] 0x00 Logical Node ID of node whose "B" port will be looped back. 0x08 Add Node There is no data associated with this entity.
	0x09 Master-configurable The value of this field indicates whether or not a node is allowed to become the EXNET Ring Master. Valid entries for these fields, based on the value of the Entity field value 0x09, are as follows: Data[0] Allow Master Arbitration Flag. 0x00 Do not allow this node to participate in EXNET Ring Master Arbitration. 0x01 Allow this node to participate in EXNET Ring Master Arbitration. (Default for CSP 2090 and CSP 2040 nodes)
	0x0A Ring Mode The Ring Mode entity configures the Enhanced Fault Tolerance Ring Mode. Data[0] Ring Mode 0x00 Reserved 0x01 Enhanced Fault Tolerance Ring Mode This mode adds enhanced Single Ring Redundancy with seamless switchover support, run-time software link validation, enhanced live node insertion, and overall improved performance and stability. This mode is recommended for homogenous second generation EXNET rings.
