Wet carpet under system

DEHUMIDIFIER. After you wet vac. Run it non-stop until moisture level is below 50%.

And some strong fans to circulate air.

Pull up all of the carpet and underpad that got wet, even if only damp. Open up any drywall and structure that got wet and replace anything that could not be dried out immediately. Anything that needs to be salvaged should be treated with an anti-fungal solution to prevent growth of mold. 

Thanks again to all for your responses.
Two industrial fans are now in operation.
Carpet is drying nicely.
Only a part of the room was affected.  Turns out, it didn’t get wet under the gear after all, only adjacent to it.

I'm glad none of your equipment was ruined or anyone hurt from any electrical shock. Hopefully you can salvage the carpet and find where the water came in to prevent any future problems. I had a whole finished basement ruined because of water coming in during a hard rainstorm. Good luck in  getting everything cleaned up and back to normal.
