Hi there!
It looks like I've joined the family! Two Tuesdays ago I saw a link to this thread on Reddit. I spent some time reading through this thread then immediately bought an ICX6450-48P off of ebay! I got it for the low price of $139 Canadian. No complaints there! What drew me to this particular switch was the 10gbE ports, the PoE, and the comment that the fan is "nearly silent" since this will be in my living room for now. I would prefer the 24 port version but none were available so 48 port it is!
It arrived by the Friday. It was in almost perfect condition save for a slight scratch across the top of the switch. Very clean inside too, components looked in good shape. The date stamped on the inside of the case was September 2012. I turned it on, and this thing was anything but "nearly silent" lol. I ended up pulling out my trusty rusty analog Radio Shack decibel meter. At three feet it was 80dB then when the fans spun down it dropped to 74dB! Disconnecting two of the fans it read 70dB at start, dropping to 65dB. Not living room friendly lol. I got a console cable on it and saw that the firmware version was 07.4.00dT31. So I hoped it was due to being an old firmware.
I started working through the guide but found the commands listed didn't work - I assume because of being an older firmware. I dug through the '?' menu until I found the commands that did what was needed, but I was unable to find a command to update the firmware with tftp. I had a look at the webui and saw there was an option to update the Primary with tftp. No option for uboot, so I told it to update the Primary and rebooted. Lo and behold the commands worked as listed. The best part: the fan is a LOT quieter now! I started the guide from the top and updated uboot, then went on to updating the PoE firmware and all the rest, and now I have a fully working, fully licensed 6450-48P. This is awesome! I'm going to learn a lot with this switch!
I've read through the first 100 pages of this thread, and the last 55 so far. I've learned a lot from everyone here, and enjoyed reading your adventures. So felt I should post mine!

Fohdeesha, this is an incredible resource and I've contributed to your liquor fund. It's much appreciated!
My next step is to get a replacement fan. The single fan is still too loud for a living room so I'm looking into getting a quieter fan.
I'm also looking into getting a couple 10gbE cards. I was looking at the Mellanox MCX311A cards, but about all I can find on ebay come from China so I'll be waiting a month. Any alternative cards one can recommend that I might actually be able to find?
I also saw a comment to not use heatpaste on the heatsinks? And that the clips break easily? Being a 10 year old switch I thought it might be good to freshen it up, but not if it's going to cause problems.
This has been fun so far, thanks all!
