Resolution

Check your PacketShaper's configuration from Diag information before and after a restart. You don't need to RMA this unit if you can see following information.

Before continuous restart.

Interface info:
----------------------------------------------------
  Inside MAC Address:        00:60:fb:XX:XX:XX
  Outside MAC Address:       00:60:fb:XX:XX:XX
  Right_Inside MAC Address:  00:60:fb:XX:XX:XX
  Right_Outside MAC Address: 00:60:fb:XX:XX:XX

After continuous restart.

Interface info:
----------------------------------------------------
  Inside MAC Address:        00:60:fb:XX:XX:XX
  Outside MAC Address:       00:60:fb:XX:XX:XX
  Management MAC Address:    00:60:fb:XX:XX:XX

----------------------------------------------------

Standby type info:

The reason for this continuous restart was "PacketShaper could not find LEM."

Do not unplug the LEM from your PacketShaper when standby mode is set to DIRECT.

Additional Information:

Booting in safe mode will fix your configuration problem, so your PacketShaper can automatically escape this continuous restart.

See KB4535 for an article that explains how to boot in safe mode.
