Port Verification
When connecting to select devices, such as PowerFlex 750-Series drives, the Port
Verification dialog box displays if device conflicts are found during the
connection process. These conflicts typically require resolution before the
connection is established with the device.
The information and options available in this dialog box are detailed here:
Common Symptoms and
