Catalyst 6K additional supervisor

[de1denta]

Hi All,

We have a Cisco Cat 6500 with a single sup2t and I have been tasked to add a secondary sup2t for redundancy. The secondary sup2t is new and will a different IOS image installed in flash.

I have checked the procedures and its not fully clear if I can simply insert the new sup2t and it will download the IOS image/config from the primary supervisor automatically or if I need to manually copy between the supervisors, can anyone confirm?

Thank you

Nope, it will not.

Thanks Leo,

So will there be any issues with installing the second supervisor card that is running a different software version? Once its booted, can I simply copy the IOS from the primary supervisor to the secondary using 'copy bootflash:<ios image> slavebootflash:<ios image>' and the reboot the secondary?

Because both Supervisor cards will be running different IOS, the second card will boot into ROMmon. 

Copy the IOS from the active Supervisor card using a USB flash drive and then force the new card to boot this IOS using the command "boot usb0:IOS_filename.bin".
