I've been happily running with my Brocade ICX7250 48P-2X10G switch for a few months now. Recently I observed my Proxmox cluster nodes regularly rebooting my VMs and I think I have traced the problem to the Brocade switch. It seems to reboot intermittently multiple times per day and I don't see an obvious pattern to it.
I have syslog remote logging to a server so these logs persist whilst the show logging outputs don't seem to survive a reboot. I don't see anything weird in there other than regular warnings along the lines of:
May 26 19:42:24:A:System: Stack unit 1 Temperature 67.0 C degrees,
I see this steadily rise to about 80C then at some stage a reboot occurs and the temperatures can be closer to 60C again then start rising.
I wonder then if these issues are actually thermal related despite being below the shutdown temperature of 105C? I also note that recently I discovered one of my ports with an SFP+ to 10GBaseT adapter was not blinking LEDs or providing a network. On replacing the adapter the switch quickly went into a boot loop with all amber LEDs. I had the system powered off overnight then next day it powered on ok with the adapter in except for this more intermittent boot looping.
Am hoping someone can make sense of this/have seen something similar in their own switch, and suggest how I can fix this. Any advice would be very much appreciated at this stage as aside from this new issue I have been very happy with this device. Thanks for your help!
