We are planing to install NM-16ESW on the cisco 2600 router and cisco 2800 router.
but there run on IP BASE IOS version
c2600-i-mz.123-1a.bin and c2801-ipbase-mz.124-1c.bin .
I think that IP BASE IOS does not support NM-16ESW module it work well only IP PLUS IOS Version.
Does any one tell me the minimum IOS version to run NM-16ESW module on the Cisco 2600 and Cisco 2800 router?
