There are rumors that it's the same as a Dell something or an HP something else, but no one has outright said, "I loaded a Dell XXXX firmware onto it and solved all of the random ass bugs." 

I managed to brick one of these by loading the wrong firmware, or doing it at the wrong layer.

I have gotten a few more and these are great switches for home or environment where you have a spare on hand.  You can usually get them for around $100 on eBay.

The firmware is *really* not designed for anything fancy but I’ve been able to drop in a variety of optics and have it work without issues in the 10G ports.

Check the flash on them as there is a primary/secondary flash once you’re past the boot image.  (Don’t try to flash it from that level, that’s how I killed it at least).

I tossed a few different firmware versions I extracted here, as well as the flash0/flash1 images and the doc i found for it.
