RE: [Trinux-talk] Re: When the device is receiving the heartbeat

Remember y'all, the link light only
indicates that a completed circuit
exists. It does not indicate anything
about the quality of the circuit. If a
cabling contractor is testing installed
lines with a simple continuity checker,
and not a CAT5 or better tester, then
the lines are not truly certified CAT5.
Oh yeah, and fire them quick!

Now that you mention it...  I too have
had situations where the cards had
link lites, but no talk...  But I never
had a card that talked with a link
lite that was dark...

I once found that due to cable
length/quality issues, one nic card was
trying to do 100 mbps and the other
10mbps.  Link lites were on, but
nobody home...
