Karla,
Retagging a DMP-4300G to become or look like a DMP-4305G is not a supported
task or procedure. Altering your DMP-4300G will invalidate any service aggreements
that you may have on the DMP.
DMP-4300G is NOT supported with DMS version 5.2.x. If you need or want to go to
DMS 5.2.x for your DMS install, I would recommend that you purchase DMP-4400G or the
upcoming DMP-4310G to replace your DMP-4300\05G devices.
Please contact a Cisco Partner, Your Cisco Account Rep or Sale Rep for more details.
Cheers!
T.
