I recently acquired another ICX6610-48P from eBay for dirt cheap. It was sold as being bricked ("It stopped booting fully after a firmware upgrade"), but that's fine with me - my primary reason for purchasing it was to swap the 40 GbE daughtercard into my existing, functional 6610 that has one defective 40 GbE port.
Just for grins, though (and before I go through all the effort of taking both of them apart), I pulled a PSU and fan tray from my working unit and stuck it in this one to see what state it's in.
It's stuck in a boot loop of some kind. The PSU fans rev up upon having AC applied, run for a couple seconds, rev down for a few seconds more, and then rev back up again. Repeat x inifinity.
On the console, this is what I get (over and over again). Hitting 'a' or 'b' as prompted looks like they work, but they do nothing to interrupt the boot looping - it just reboots again a few seconds later.
Code:
ICX Boot Code Version 10.1.00 (grz10100)
Enter 'a' to stop at memory test
Enter 'b' to stop at boot monitor
Boot(Mem-Test)>aaaaaaaaaaaaaaa$
ICX Boot Code Version 10.1.00 (grz10100)

Enter 'b' to stop at boot monitor

Any hope of recovering this short of JTAG?
