Check cables first. It might be a
quick fix and are the cheapest
parts to replace. – cont.
Check Hub's communications.
This is not very likely to have
gone bad but it's much easier to
replace a hub than any head.

Explanation/Solution
A cable that has shorted out has
the potential to cause damage to
multiple heads!
A good test of the cables in
multiple head systems is to
temporarily disconnect cables so
that only the first head is
connected to the hub. If all is well
after a hub reset the first head
should not be indicated as a
problem on the LEDs or
VeriColor Software when
connecting.
Now add on one head at a time,
giving the hub a reset each time.
Check back with the hub's LEDs
or consult software.
Eventually one connection will
still reveal a head to be missing
or cause other previously working
heads to missing too. This is the
cable to be replaced.
If replacing cables do not fix the
problem, go to the next section.
If you have a spare hub, connect
the heads to it and apply power. If
you are able to measure with all
heads then your original hub was
the problem.
If you have a spare known good
hub and cable, connect them up
to the original hub and use
software to determine if it found
the right Head Serial # for
"Reported Head List". Remember
to reset the hub after connecting
the spare head.
If the original hub works with the
spare head, the problem exists in
one or more of the original heads.
