Hi, one of our MS120-48 poe switch keep hang (red light), after power cycle, it can run for a few hours , then hang again. Anyone can advise whether it is hardware issue, it is brand new one. Thanks in advance.
10.44 is the current stable. You could try the current Beta which is 11.4 but I doubt it will help.
Getting the switch swapped out might indeed be the best way to go. Maybe there's a hardware issue with it. Especially if you have no problems with other switches.
Event log doesn't say anything about that particular switch right?
yes, event log nothing, only stp info, but it looks not related. I will try beta version, most probably it is hardware issue because another switches same version but running well.
