Upgrading Supervisor in Cat 4500

[bgl-group]

I have a 4510R-E chassis which currently has a single supervisor 5 installed.

We are now looking at upgrading the supervisor to a Sup6. Now the question is this, can I install the Sup6 into the redundant cpu slot and then perform a failover to get the new switch working without any noticable downtime.

I'm not sure what having a Sup V and a Sup 6 in at the same time will do to the backplane.

Otherwise I have to take the switch down and then install the card and software manually.

Thanks

No, you can't configure 2 different sups in redundant (SSO or RPR) mode. This change will require an outage window.

Thanks for the answer - I thought that would be the case. Looks like a middle of the night job for me again...
