I know that the 3700 itself will drop to 3x4 MIMO if it only gets 15.4W of power (takes 16.8 with 4x4). If I add in a WSSI module, I know that is not enough power to run the WSSI module. We'd like to deploy our APs with the module installed and light up WSSI only as we get 802.3at power available. What I don't know is if the AP will light up as 3x4 with WSSI disabled, or if the AP will just completely fail. I should get a chance to test this soon, but if you happen to know, please tell!
Thanks!

If you have enough power to the AP, you can look at the GUI and under the main screen under Access Point Summary, you will see Dual-Band Radios... the WSSI or WSM will show up there.

I believe with just 15.4w PoE, the WSSI module won't power up.

Yep, the AP w/WSSI does power up and service clients on an 802.3af port. Not sure how to tell if the WSSI module gets powered up or not (I presume not...seems to be either a black hole in the AP status on the WLC UI, or it's not intuitive).
On 802.3at port, the AP draws 16.8W without WSSI, or 20.7W with it.
