That is also one thing we have found with TP Ethernet. Mod jacks have to be suspect since they can become loose and can cause unusual errors. Another reason the lights are nice with Cabletron. >We used the patch cords for maximum flexibility and >I believe this to be a mistake.

I wonder if you use the little finger trays between hundred pair sections for patch cord organization? If you use the plastic, screw-on-the-wall type 110, patch cords all hang in front and make a mess. The little finger trays on the 110s installed on metal troughs are much nicer for organizing large panels. We also put D rings in between the vertical columns of 110 for organizing patch.
