[c-nsp] Cisco 6k no power enable module

[Matt Addison]

The bus stall is due to the physical pins in the LC making contact,
disabling power to the slot will not avoid this.

We also just labbed a VS-S720-10G running 122-33.SXJ1 and were able to shut
a slot down without a module installed. Unfortunately we ALSO were able to
incorrectly install a WS-X6748-GE-TX and cause the 3 second bus disruption.
Anyone else run into this?

Anyone know why Cisco doesn't allow for you to shut power down to a
slot/module unless a FRU is installed in it? We can reproduce 100% multiple
times in the lab WS-X6748-GE-TX installation's that causes the bus to stall
3 seconds. It has to do with the force you apply to the card during
installation.

%C6KERRDETECT-SP-2-SWBUSSTALL: The switching bus is experiencing stall for
3 seconds
%C6KERRDETECT-SP-2-SWBUSSTALL_RECOVERED: The switching bus stall is
recovered and data traffic switching continues


Router(config)#no power enable module 8
%FRU Absent. Power admin state updated
