[e-nsp] failed POST on summit?

[Josh]

I just picked two used Summit switches (a 48 and 24 - older
series, not 'i').

When they boot up they show:

So the mystery is that the green light flashes properly after bootup
(which indicates POST was ok according to the manual) - and the
switch seems to work ok.  How do I figure out what the 'failed'
is in reference to?  Could this be due to just not having GBIC's
installed?  Or is this a real hardware issue?

Thanks for any help!
