Extreme Networks 5420M

[BoGs]

I have tried to search on the forum but there is little extreme networks stuff. I happened to stumble on a 5420M-24W-4YE and jumped on it as impulse buy lol. It seems there is not much information on the internet about it outside of contact support, which will not happen since I will be running it in a HomeLab for some POE++ devices.

Anyone able to point me to what software to run? I saw some posts about potentially ONIE, but would love to know more and learn more. I am hoping to just use it as access switch. I am unsure what the software would be, or if it comes with it, etc. etc.

Thanks for any tips in advance.

It should have an OS installed, but you might need to flip it from Fabric (VOSS) to EXOS depending on how it was installed before. The knowledge base will help you out for specific things, it's pretty good. The only thing I'm not sure of is how to clear a password if the seller didn't do that.

If you can log into the console through a serial port (usb to serial built into these with the small connector on the right side), then you can issue:

unconfig switch all

This will reset to factory, but only works in EXOS, you might need to try FULL in the above command, it's been a while since I had to clear one.

I have a 5420m-48w-4ye in my lab and a bunch of different models in production. Not an expert with them, but can make things go when needed. The only downside is they lock firmware updates behind a support contract (like many other companies), I disagree with this policy and keep working for a change for at least lab use.

I should probably add that tab will generally complete a command word, and ? will pull up context help for the command you just typed.

And I did look really quick and there is a way to reset things through the boot loader, but I've never tried this. Involves deleting a bunch of file and reboot. And when searching for help, the answer might be given for the 460 series of switches, it's pretty much the same internals and OS images.

Awesome thanks a bunch, its on the way will try when it gets here.

If the VOSS is new enough, the unconfig also works. And if it is in VOSS, I think you need to go into the bootloader to change to exos, no sense being in fabric mode if you don't have a bunch of other switches to form a fabric.

These switches are pretty nice, only thing left out is full routing, that's an optional license and something you might want to check and save before you wipe it.
