Need Help to boot Cisco2621 Router

Greetings!

I accidentally deleted the IOS files in the flash memory. And when I reset the router I got the ff error:

Device does not contain a valid magic number

boot:cannot open flash

boot:cannot determine first file name on device "flash"

Could anyone help me on how to get this router running.

Thanks.

Re: Need Help to boot Cisco2621 Router

Sounds like your 2621 is booting into ROMmon, and your flash memory is empty. You're going to need to copy a valid image onto it again.

First, get a copy of the IOS image you need (a file name that begins with c2600- ). Then work your way through the following links.

Start here:

ROMmon Recovery for the Cisco 2600 Series Router and the VG200

http://www.cisco.com/warp/public/130/recovery_c2600.html

Then go to one of these:

How to Download a Software Image to a Cisco 2600 via TFTP Using the tftpdnld ROMmon Command

http://www.cisco.com/warp/public/471/76.html

or

Xmodem Procedure for Downloading a Cisco IOS Software Image onto a Cisco 2620 Router

http://www.cisco.com/warp/public/130/xmodem_generic.html#download_2620

Hope this helps.

Thanks.

I already found the link just after I posted this question and have yet to try it.

I'm just new to cisco routers and just finished my CCNA training. And right now reviewing for the exam and have one Cisco 2621 as my hands-on unfortunately I accidentally deleted the IOS. Hope this will work.

Thanks for the help.
