Point-to-Point Initialization Failure
1. Confirm that the port is active
If a Fabric device or another switch is connected to the switch, the switch port

b. Verify that the State Change Notification (SCN) code is 1. An SCN of 1
indicates that the port is active.
Example:
2. Skip over the loop initialization phase
After becoming an active port, the port becomes an F_Port or an E_Port,
depending on the device on the opposite side. If the opposite device is a Fabric

the port becomes an E_Port.
Some Fabric devices have problem with loop initialization. If this is the case,
perform the following step:
— Enter the portCfgGport command.
