Hi,

I hope you will have the IOS in TFTP server. If not, download from CCO and copy the same to TFTP server.

Now copy the same from TFTP server to router flash card using "copy tftp flash" command.

Hi,

Yes. Removing flash card will not bring down your router. THis can be done with your router up and running.

Hi,

Am I right assuming that your question is that, you have a 2851 router which have flash card loaded with old IOS and your new IOS doesnt fit in this flash. So you ordered a new flash and want to know how to load the router with new IOS?.

If yes, you can remove the old flash when the router is up and running. Now place the new flash with new IOS. If you dont have the new IOS, you can download the same from TFTP to your flash card. Make sure the new IOS is not corrupted while downloading from TFTP and reload the router.

Let us know if your question is not what I answered for.

Hi Thanks for the post,

Yes, your guess is totaly correct.

But, what is this "Now place the new flash with new IOS" , How you get the new IOS to new Flash card

If that is the case, upgrade is very simple.

What you saying is, I can remove the current Flash card without any command to shut down the Flash Card, and incert the new one

So if I ge the IOS in the new Flash, after reboot I should get new IOS image loaded in the router
