I am moving from 3com dummy switchs to 3 JGS524Ev2 switch's all had the older 2.0.1.26 firmware. I had windows 10 stations that were not able to use microsoft apps or update after moving most everything over to these switch's so I figured upgrading firmware would be simple I would do 1 at a time then pull the last remaining machines off the 3com switchs. When I upgraded to the newest version for these switchs (2.0.1.40) on just one switch it created a issue where I was no longer able to log in on chrome I figured no biggey. Then it kicked off everyone on the other switch I did find I had a bad ethernet cord on a connected switch and unplugged that and it seemed to settle down but that had never been a issue before. Should i revert back to the older firmware? I am worried now that I am going all in with netgear that I made a mistake as this is not confidence inspiring.
Awesome thanks I should have all cat 5e but I will check as this is a over haul for a call center this had me freaked out. Seems like everything has calmed down now maybe that shorted wire was causing a loop I can even log into the switch via chrome today without having moved any wires.
Model: JGS524Ev2|ProSAFE Plus 24-port Gigabit Switch
Please avoid forming loops for network environment. If you see all ports LED blink quickly, and you cannot login the switch, maybe loop happens.

Yeah the really strange thing was without changing any of the hardware except the firmware change I wasn't able to navigate to the switch via chrome but I could with IE that is what threw me. I am glad I found that loop it has probably been there for years as it was installed by someone else.
