Upgrading your Redundant Sup 720 - Part II
by admin on Jan.30, 2007, under Networking, Routers
Tries to go through the maintenance of upgrading our CSM and the IOS on our Sup 720s this past week and ran into some problems. The CSM upgrade went well but after rebooting the CSM with the new software one of our Sup 720s burned out. It was one of those freak things but now working on getting the Supervisor replaced and will be finishing the IOS upgrade then. I had a couple of documents in this post to help you with your upgrades.
The following is some good info for upgrading your CSM when you have a Sup720 instead of a Sup 1 or 2.
CSM> upgrade 127.0.0.zz c6slb-apc.revision-num.bin
The zz is 12 if the supervisor engine is installed in chassis slot 1.
The zz is 22 if the supervisor engine is installed in chassis slot 2.
