I have just receieved 2 IBM x345 Servers that I will be using to replace our older Call Manager servers. I am trying to install the OS on the x345's and get the error using the hardware detection disc that the software is not supported on this server. I have made sure the server parts are exactly what are required for call manager support, so I'm not sure what to think. I did read somewhere that the X345's need version 2.6 O/S for use with call manager, what I would like to know is that both the hardware detection discs I have tried (one from 3.3(4) call Manager and the other from 4.01 both are version 2.4 OS 2000. Will these discs work or do I somehow need to get 2.6 direct? Any thoughts or suggestions?
