[c-nsp] 6500 line card mounted cable management bars (??)

[Brian Fitzgerald]

There was the old rj21 telco that Cisco used on the 10 and 10/100 cards for
the 6500- but it was big and bulky, and only good to cat4/5.

There is a newer connector - the MRJ21 - that terminates 24 pairs of cat5e;
giving you 12 ports of 10/100 or 6 ports of 10/100/1G or PoE.  It is small
(about 2cmx4cm), rated for high speeds, and gives decent density.

The MRJ21 is a Tyco/Amp patent, but liberally licensed to others (ADC,
others), and used already on Force10's E series high-density (90 port)
copper cards.  Lots of modular solutions, cable assembles, patch panels, etc
available.

Now just have to convince Cisco after they were burned going with the MTRJ
fibre connector...
