12345Kevin, From the technical update course for 7.1:
"You can install up to two Quad CIM's in any 3300 ICP Controller, with the exception of the AX controller which only supports one quad CIM.
On CX and CXi Controllers, only the first 3 prots on each Quad CIM are functional -- the fourth port is not supported"
MitelDude, it would appear you are good to go (as long as your software is 7.1 or better.
