The 30-year-old had already been fined £2,000 by magistrates after pleading guilty to assault and resisting arrest in the Crown dependency.
Gloucester have now issued an identical fine to Cipriani and ordered the England international to undertake an "additional 10 hours of community service".
"Having reviewed all the facts and spoken to both Danny and Willi Heinz, who witnessed the events first hand, we are in agreement with the Magistrate in Jersey that this was a minor incident," said a club spokesman.
"While Danny is very apologetic for his actions, we do not believe he is guilty of bringing the game into disrepute and he will continue to get our full support.
"Danny has now faced disciplinary action from both the courts and his club and, with the new season about to kick off, our focus is very much on preparing for Northampton on [September 1]."
Cipriani was left out of Gloucester's matchday squad for their pre-season friendly against Ulster in Belfast on Saturday.
