N3048 Switch Randomly Crashed

Have a fairly new Dell N3048 switch on our network. Had it for several months in production working just fine. Yesterday the thing randomly died with no external anomalies known. The device was powered off. We have two PSU's in the unit. A tech that investigated said one was on blowing warm air and the other was off. He found that odd as the room is quite chilled and the unit is always cool to the touch and blowing out cold air from the device. The switch is plugged into two separate backups systems.

Any ideas? Running 6.2.0.5

Logs pulled from the device (starts at bottom. sorry for the ordering)

RE: N3048 Switch Randomly Crashed

Forgot to mention that the tech had to remove power from the device and plugged it back in. The device came back up and everything is working properly. But now I'm afraid I'm going to have random non-recoverable failures in the future.

RE: N3048 Switch Randomly Crashed

I could not find much info based on the logging messages. Is this a PoE switch? Or is the second power supply just for redundancy? In the Web GUI under System > General > Health, it should display the status of the hardware. Does everything there look ok?

Second PSU just for redundancy, no POE. The system health shows everything as great. I can't find any issues or cause but it definitely crashed into a powered-down state.

RE: N3048 Switch Randomly Crashed

With everything's status showing as good, it may be hard to pinpoint the exact cause. I would continue to monitor. It could be a one off situation. But It also wouldn't hurt to open a support ticket, just to document the occurrence.

RE: N3048 Switch Randomly Crashed

Odd..... We have lost connectivity to the management interface on the stack master.  I cant even connect to it from putty or a serial connection.  It pings and seems to connect fro telnet or serial but no interface screen comes up...... This is getting dire.
