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)

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.
Total CPU Utilization 5 Secs ( 18.4377%) 60 Secs ( 12.2220%) 300 Secs ( 11.2987%)
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.

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.
