Install redundant supervisor

Unanswered Question
Dec 15th, 2008

Hi folks

I have a 6513 with one Sup720 and IOS 12.2(18)SXF5. I'm planning to install a second Sup720 and my question is this:

Are there any obvious "gotchas" when installing the secondary module? More precisely, can this be done without service interruption?



I have this problem too.

This process can be done quite easily, and pretty painless. Ensure your new (secondary) SUP720 has and will run the same IOS version as the primary and that's it. When the new supervisor boots it will pull the config from the primary. Here's an excellent guide that should help. You should not incur any downtime adding a redundant supervisor.
