I think it sounds like you're making the assumption that there will be equipment in the various racks scattered about. I've wired a lot of offices where all the servers etc are located in a single closet, and if there's another closet located out there somewhere ... The 2nd closet is nothing but network cables. Generally for the sake of having a network closet within Ethernet copper cabling range. _______________________________________________ Tech mailing list Tech@lopsa.org http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
