Hi all,
We had an MGC-100 running version 6.0. After trying to upgrade to 9.0.3 the MGC is not booting anymore, we can't login to it.
I guess we should have upgraded it to an intermediate version. Is there any way to reset it back to the working version 6.0?
Thanks a lot.

Eko,
As your MGC was running ver. 6.0 I guess it has a floppy drive (not compact flash). If it's so you have to create a Resque disk and boot MGC using this one. So you need:
- Find MGC software ver. 6.0
- Find the image of the MGC Resque Disk and the appropriate documentation about using it
- Find the 3.5" disk in usable state and a PC with floppy drive
- Make a bootable disk (with OS compatible with resque utils?)
- Using this disk, keyboard and monitor attached to MGC control module make MGC able to get software
- Upload S/W ver. 6.0
- Enjoy the result
Please keep in mind that you need a dongle (hardware key) attached to MGC and configured to support the desired S/W version. Every time you want to upgrade MGC to the next version (6.x to 7.x, then to 8.x, then to 9.x) you have to get the new license (*.don) file from Polycom support site.
I wish you good look - you'll need it!

Hi Mike,
Thank you very much for the detailed explanation.
The MGC-100 was running S/W ver 9.0.4 with XPEK kernel. The Control Unit went defective and I inserted the spare Control Unit which had S/W ver 6.0 installed. The dongle was 9.0.4. I was able to connect to the MGC from the Manager and started the upgrade to 9.0.3. After the upgrade finished, I reset the MGC then I could not connect anymore.
I created a Rescue disk, but was not able to upload 6.0.
I got confused, control unit with ver 6.0 and the dongle 9.0, should I have downgraded the dongle to 6.0 and then started the upgrade to 9.0?
Regards,
Eko

Eko,
In my old notes I can find next things about updates:
- Control units compatible with ver. 7.0 and later: ASY0182P and above, ASY2019G and above
- Control unit must have at least 128 MB of memory to run ver. 7.0 and later
- Free disk space must be at least 130 MB to run ver.7.0 and later
Please note that not all boards are compatible with different S/W versions, so it may be useful to remove all functional modules when upgrading/downgrading.
Also note that XPEC and PSOS resque procedures differ one to other.
Hope this could be useful for you
WBR,
Mike
