I know the question has been asked millions of times before, but I don't think I've seen this answer. While I was browsing CCO, I came across this snippet at http://www.cisco.com/warp/public/63/7500_faq.html#Q9
Q. How Can I Find the Serial Number of My Cisco 7500 Chassis? A. The show rsp chassis command was introduced in Cisco IOS. Software releases 12.0(13)S and 12.0(13)SC. This command will be supported in future releases.
