[c-nsp] Shutting Down Catalyst 6509

[Mark Kent]

>> My concern is 'how do I shut the switch down'?

In addition to the "turn it off" replies, if you wanted to be
super-careful you could:

a) wr in the msfc

b) from the fwsm system context, "wr mem all", then force a fail-over
   to the other 6509/fwsm you have (you do have another, right?).

c) Do "no power enable module 1" (replace 1 with the actual slot number). 

d) Repeat b+c for any other FWSM/ACE modules.

e) remove power
