It doesn't really matter whether you have powered off a slot or not (the module is
recognized even when powered off).
As soon as you oir the module, a bus stall will probably occur. We have seen that multiple
times.
Theoretically if you know how to insert/remove the module (not too quickly, not too
slowly; it's a known pins "issue") you shouldn't have this problem,
Personally, i always had 100% success when doing it myself, but i don't expect everyone
else to be so lucky.

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?

Subject: Cisco 6k no power enable module
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_RECOVERED: The switching bus stall is recovered
and data traffic switching continues
Router(config)#no power enable module 8
