my company bought an ACS 1120, no SMARTNET support of course, and I'm getting prepared to deploy it.
I've litterally gotten it out of the box and powered it up...
in the box came several CD/DVD's of which is ACS 4.1 for windows; 4.2 for windows; and one that has a copy of a Windows Server (looks like a special version, i'm writing this post from home and dont have the CD's in front of me, sorry)...
My question is merely, do i ust run through the initial setup prompts? And is it necessary to start at 4.1 and upgrade as I go (ie...4.2, then 5.0)??? Or can I go straight to 5.0?
The ACS 4,x software you have been shipped is to assist customers who need to migrate from an earlier 3.x/4.x release. If they are on a specific 3.x release they can upgrade,using the disks to 4.x and then perform a migration procedure to ACS 5.0/5.1 tomigrate certain subsets of the data. The migration procedure requires ACS 4.x to be installed on a windows PC so the disks can also be used by customers who have a closed 4.x appliance and need to backup the database and then restore data onto an ACS 4.x windows based installation created using the disks provided.
For new installations these disks are not applcable and just need to run the basic setup. However, as others have suggested, if you are just getting started, I would recommend downloading ACS 5.1 from CCO and reimaging so that you can work with the latest version. Note the ACS 5.0 license can be used for ACS 5.1 as well
ACS for WIndows (whatewer version you have) will run on Windows 2003 server (see inatllation requirements for details) ACS 5.X exists only as appliance or VMWare image. In general - appliance is more hardened in terms of viruses and intrusions
If your goal is to have ACS 5.X running, then go straight to it, download ACS 5.1, which has most ACS 4.X features.
If I am not wrong your 1120 should already be running ACS 5.0...but just in case you should also be able to download the DVD from CCO:
You will require a valid license for ACS 5.X, which will need to be issued by the Licensing Team.
If you prefer you can stay with ACS 4.2; you would need to intall the "ACS 42. s/w for cisco 1120 appliance", this type of ACS will be preinstalled with the OS and you cannot access the OS.
The migration from ACS 4.2 to ACS 5.X is not something recommended since they are totally different breads!
