Why is the WiSM2 not recomended in the Sup slots?

[rhodrijenkins]

I have a situation where a customer doesn't have the required power units installed in theior 6500 for me to provision a WiSM2.
They use a VSS paiur with a single Sup720 in each. They have no intention of adding a second Sup to each chassis.

I need to justify why they can't use slot 6 (which has power reserverd) if I am to get them to upgrade the PSU's. The documentation I've found says it is supported but not recomended. Does anyone know of any cast iron reason why this is not recomended.

Cheers in advance
Rhodri
