Cisco Smart Install, opens up TCP port 4786, want it disabled

Hello, I have upgraded a couple of 2960G switches to 12.2.52SE and now discovered that TCP port 4786 is open on the switches.

I have looked in the document http://www.cisco.com/en/US/docs/switches/lan/smart_install/release_12.2_52_se/configuration/guide/smart_install.html trying to find a way to disable this function/port, but didnt find anything usefull.

Have anyone found a way to disable this function/port?
