Hi,
I tried to install the RAM named MEM-MSFC2-512MB on a supervisor engine 2 (product name WS-X6K-SUP2-2GE) e it works!
So now I have 512 MB of RAM on both SUP2 end MSFC2.
Just to know I had some problem with the supervisor's boot register because it booted in rommonitor state. I set it in 0x2102 like the msfc2's boot register.
(To know the supervisor's boot register, the command is "remote command switch show bootvar", but I changed by rom-monitor console)
Bye to everyone!
Giorgio
