Cisco IOS Upgrade

Medium Priority
Last Modified: 2012-06-27
I found that i need to install an IOS upgrade to my router to use the HWIC-1FE module I purchased.  I have a Cisco 2821 router. From the spec sheet i read that i need a minimum IOS of 12.4(15)T.   I called my Cisco retailer and he send me the following file c2801-advsecurityk9-mz.124-22.T.bin . When i tried to load this it says it is not for my hardware.  I am guessing this is because it begins with c2801 and i need it to be c2821?  Should i ask for a different file?  Could i just rename it?  Thank you for your help!

Hope this help.

You cannot use c2801-advsecurityk9-mz.124-22.T.bin as IOS are platform specific

This is the IOS you need to go far c2800nm-advsecurityk9-mz.124-22.T.bin

I would not suggest changing your file name since I doubt the source of the file. Download the uggested IOS fresh from website and always verify MD5 checksum after copying it
