Markhenry,
With the terminology that you are using I would say that you have an Axxess system and not a 5000 system. The CPS was replaced by the PS-1, a Linux based server. I am not sure what you mean by serial cable connections off of the CPS as it always used IP for that connection, but you may be looking at the VPU[EM] that has a serial cable "look" to it that connects to the a CPC or CPU in the Axxess Cabinet and those servers can look similar. If I am correct that it is an Axxess then it is no longer supported for upgrades to newer versions of software and therefore newer servers and OSs.
To give a little history here the Axxess was replaced by the CS-5000 series platform that came in three version:
1. CS-5200 the base system
2. CS-5400 a PEM [Processor Expansion Module] is added to the Processor Module of the CS-5200
3. CS-5600 a PS-1 [Processing Server] is added as a seperate server to communicate with a CS-5400, which means that you had to upgrade the CS-5200 to a CS-5400 and then add the PS-1.
Now, we have the HX-5000 series platform which follows all the same rules as above, but they are no longer designated as 5200, 5400, or 5600 even though some installers may still use that terminology to differentiate the type of hardware used when talking to one another. The most obvious difference in the two is the form factor used for the base system, as well as the cards that fit into the cabinets, but the expansion cabinets called DEIs and the PS-1 are still the same.
As for the Inter-Tel Data Manager and Contact Center Manager those can be upgraded to the latest versions and put on a new server, although it is no longer call Contact Center Manager.
Thanks,
TE
