There were no ServerUpdateInstaller.exe
so the 4 server packages had to be installed one-by-one.
The new version after the update is 4.0.7577.108.
The update was very quick and everything started up and worked well after a reboot.
My Lync Client changed
and so did my Topology builder
but the Lync Control Panel stayed at 4.0.7577.0
