Downgrade ACS 5.0 to 4.2

Hello all,

i just got my 2 ACS boxes  and they are pre-loaded with ACS 5

My problem is that all my documentation, test plans, schmatics etc were made on ACS 4.2

Am also using feature from 4.2 that are not on 5

I tried downgrading the appliance by booting on the DVD ( ACS 4.2 recovery that came with the box )

my problem is that the setup hang juste after loading the mscdex ( win95 boot )

Since it can boot on the DVD, the hardware is a DVD ( A CDrom would not read a CD )

i cannot get to the 1-2-3 menu... i try burning a copy of the dvd without any luck

Any idea?

Which features are you missing on ACS 5?

If this is the main issue you may want to consider ACS 5.1 that has additonal features beyond ACS 5.0

Re: Downgrade ACS 5.0 to 4.2

There is no PEAP-TLS support in ACS 5.1 at this time:

As for the DVD problem, try burning a copy with your burn speed set as low as your burner will allow.

The DVDs can get corrupted at times when using high burn speeds.

Re: Downgrade ACS 5.0 to 4.2

Hi guys

I had the same problem,the fix is:

serial console 9600,8N1 only with Hyperterminal and it works.

SecureCRT or ZTERM are my faivorites but only Hyperterm worked for this issue.

Cisco Secure ACS: 4.2.0.124

Appliance Management Software: 4.2.0.124
--------------------------------------
Acs Appliance Recovery Options

  [1] Reset administrator account
  [2] Restore hard disk image from CD
  [3] Exit and reboot

Enter menu item number: [2]

This operation will completely erase the hard drive.
Press 'Y' or 'y' to confirm, any other key to cancel:y

Please wait while Cisco Secure ACS image is restored.
This might take several minutes ..

Regards

Alain
