If you encounter stability issue after upgrading firmware to ZLD4.60, PROVIDED THAT YOU’RE RUNNING FIRMWARE VERSION:

  • ZLD4.39C0

The Symptom:

The firmware listed above is subject to a bug. When FQDN object is created and

used in the system configuration, the device may hang after upgrading firmware to any newer version. However, if the device is running firmware version that is not listed above, then your device is immune from this symptom. Lastly, if you didn’t configure FQDN object, then your device is immune from this symptom, regardless of the running firmware version.



Power cycle the device (power off the device completely for 5 seconds, then power on the device).


1.    Reminder: in order to perform power cycling, you must have physical access to that device. You may need an on-site visit if the device was installed in a remote place.

2.    Please backup your device configuration before upgrading firmware.

3.    If your device is running weekly build: ZLD4.39WK32, ZLD4.38WK26/30, ZLD4.55WK26/30, then your device may be subject to the same symptom.
