We've got around 20 c7000 chassis and have never had problems other than one that was DOA due to shipping damage.

If you're using Nexus switches, the B22 module for the C7000 gives you the ability to connect a C7000 chassis to a 5xxx Nexus like a Fabric Extender (FEX). I'm told they will soon support the Nexus 7000. -j _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
