6500E Sup720 Redundant Supervisor Card

Unanswered Question
Oct 22nd, 2009

Hi, I have a 6509E platform with redundant supervisor cards. I noticed one was in ROMMON (not sure how it got there) and when I boot it back up it had an older IOS. I copied the new IOS that's on the active card. Do I just need to reload the (cold) module or do I need to reload both sup cards to get the equipment in a active/hot combo? Much thanks appreciated for any response. I could not find a link on Cisco right off hand describing the process.

I have this problem too.

Hello Robert,

if you have the same IOS image running on the two supervisors you are fine.

you should follow this link


you have to add few lines to master supervisor.

if your IOS allows it you should use SSO redundancy that is the best method.

Hope to help

First of all, you should open a new thread when you ask a new, unrelated question. That way it is easier for others to search for help later on.

Secondly, are you sure that your new (SXF17) image is complete? It sounds like you might have ahd some error during either download from cisco.com or when copying it to the bootdisk: device. Try repreating that process and see if it helps.

HTH, Ingolf
