M4300 24X: sudden restarts

Hi wuebra and the Community

Please be sure that the NETGEAR Tech Support team, the NETGEAR Engineering team and the PLM team are working on these issues. To date, most cases logged in our system are resolved after PSU replacement. We are in the process of getting all faulty PSUs back to Engineering for complete analysis (root causing) so that actions can be taken at the factory as we suspect faulty PSUs. Please understand that there is no correlation between the fan speed, the internal components heat and the reboot in all your posts above. The fans are on duty "dynamically", based on internal heat sensors. The CPLD function is to make sure the heat remains under the system MAX thresholds. The CPLD is increasing fan speed when the temperature of the internal components is getting closer to the MAX threshold. In all your explained situations above, this is not what triggers a reboot. By design, the system is shutting down when and only when the internal sensors are reporting internal heat at or above the MAX threshold.

wuebra is your case number finishing with 181? For that case we replaced two switches under RMA and the NETGEAR Tech Support agents don't get responses anymore since then. 

In any case please send me your Tech Support case nuber so that I can help prioritize your issue. As we can't replicate the issue with our own devices in our labs, we are depending on close collaboration on site for exporting the logs etc. You can send me your case number or any help request using private message here. 

We are very sorry for this reboot issue on that model, litterally thousands units of that model are working well in the field and I know how the frustration can be when one unit is rebooting intermittently. We shall resolve this issue, I can guarantee! Again, please send me your Case Numbers.

Regards,
