I wonder it the difference was that we were using all plenum rated 
cable? We were running between floors and through firewalls. Like 
you, we had 24 port rack mounted patch panels on both ends. We also 
had routers and a lot of patch panels for wall jacks on one end. The 
other end was in the server room. (About 500,000' of 4 pair CAT 5 
installed.)
