Replacing a backup Sup 720

I am replacing a faulty sup720 on a 6513. It s the backup/hot not the

active sup. It has the same IOS on it. Is it correct that all I need to do is

remove the faulty and replace it with  the new sup and do a wr mem?

Fromwat I have read their should be no down time all connectivity

should remain stable?

It should work fine since you are replacing the Stand-by sup, but Just in case, do this during an outage window.

In addition to having the same exat IOS as your primary sup, make sure there is no config on it.

Hi,

As long as hardware and IOS on the New Sup is same as Active one, you won't get any problems.

No, the primary sup will Sync the config to the stand-by.   Then "sh redu" should show that the primary is active and stand-by is hot.

When I checked the IOS I could see there wasn't a configuration on it.

Replacing a backup Sup 720

when the 2nd sup comes up does it check to see if it is

the backup sup ? Does it automatically download the config from the active sup?

Thanks
