Hi Team,

When we try to perform a Link Test with the PTP 550 channel bonding, the unit reboots. There is nothing store in the logs to help us understand what is going on after reboot. Software version is 4.7.0.1.

Thank you for your feedback!  
Does it happen to any specific radio or you see it on every PTP550 that you have tried?

Thank you.
