Help with Upgrade 81C

[mistoceva]

Hi,

I need to upgrade Meridian81c rls 25.40b to 4.5 and install new 12 VGMC. I checked and the IPLine from my old VGMC (3.05.02) is not compatible with Rls 4.5 and IPLine from the new cards (4.5) is not compatible with Rls. 25.40B.
To do the upgrade I need to split the CPUs into:
- CPU 0 with 25.40B for live system;
- CPU 1 with 4.5 for installing the new IPLines.

Somebody knew how to split the CPUs that will work: on day CPU 0 with no CPU1 and on night CPU 1 with no CPU0?


Regards

when you split the cores... core 0 and cmdu 0 active, put cpu 0 in maint, turn off the cni's on core 1, press and hold the ini button, switch cpu 1 in maint and rls the ini button... core one is not a part of your switch, if you have the install disk in the drive, it will boot into the install menu.. if not it will just boot... your switch (main screen) will tell you that you are no longer rdun due to maint mode.. it will not scpu or attempt to scpu until you take it out of maint..
