We are expanding our office into some adjacent space. The space we're
taking over has some finished offices that we're going to keep, and their
drops run to a nice little wiring closet not that far from our own server
room. I figured I'd just throw my switch into their closet and run fiber or
UTP from my existing rack. I was surprised to discover that the drops
already in place are cat 6 STP (must've been put it when they moved in a
couple of years ago), but the shields have simply been trimmed back to the
jacket and are not grounded on either end. I think I read somewhere that an
ungrounded shield could cause problems and I was wondering if I need to
ground these shields somewhere? I don't want to recable but if I had to
repatch them to a panel I can ground the shields to that probably wouldn't
be too pricey, would it?

What do you think?

Big discussion on the very same subject in
comp.dcom.lans.ethernet.

So you better watch there :-)

(No, no definitive answer there neither. No yet, anyway :-)
