    Celestica D4040 32 Port QSFP 40GbE Switch $165

    Also for those curious there is another listing up, this one appears to have a MFG date after the new stepping's were released(feb 2017) https://www.ebay.com/itm/SmallStone-XP-D4040-32-Port-Switch/324163304095?hash=item4b79a37a9f:g:XwMAAOSwp49eua97 So this may be a very good deal for someone...

    I ended up finding a good deal on the Penguin Arctica 3200XLP variant of this switch that had a licensed cumulus 3.6 on it ($150 free shipping) And have been playing with that the last few days, I'll be attempting the resistor mod on this one as the motherboard looks like the other ones in the...

    Yeah I was hoping for that as well, but it would need to be manufactured after like February 2017 for it to have a c0 stepping chip.

    So this motherboard is slightly different than the one that was shown in one of the older threads: https://forums.servethehome.com/index.php?threads/celestica-d4040.24256/post-232018 The items that were being soldered to previously for the 3.3v source have now been moved to the back of the...

    Celestica D4040 32 Port QSFP 40GbE Switch $165

    Ok so this one was manufactured in 2016/02 and does indeed ship with no os on it, bit of a bummer. I'm gonna try to get sonic installed on it.

    Also @fohdeesha i saw you had mentioned in previous threads that you were looking at potentially porting other switch os's to this switch. I guess it's safe to assume the reason you haven't is because they've died on you...

    https://www.ebay.com/c/18017982470 Just ordered one of these myself, hoping it comes installed with an OS atleast. I am hopeful considering it is talking about doing a password reset. I offered $130 and they accepted. $180 after tax and shipping to texas. Maybe we can revive interest in this...
