[nsp] 7500 insertion force

[Clinton Work]

The Cisco 7500 CBUS is shared amoung all the line cards attached
to it. When you do an OIR the bus is electrically interrupted and a
CBUS complex operation is started to rediscover the cards. This usually
means that all packet forwarding stops for 20-30 seconds. If your lucky,
everything comes back and the new card is ready for use. We have run
into a lot of problems with OIR and we now power off our 7513s before swapping
line cards.
