We had some a 3424 and a 3508 die. When we RMA'd the 3524 it
sounded a lot like there were known hardware problems with them
and the exchange was quite pro-forma. The rest of that lot
are still working fine.
I'd say if it hangs up in POST repeatedly, just tell them that
it was unreliable. You should try to capture any diagnostic
output on the console port, I don't know if there's any setting
to make them more verbose.
With reference to the Smartnet stuff, most new Cisco switches are
supposed to be lifetime warranty, all smartnet gets you is an
instant replacement. Not sure what the deal is on older switches.
