Restoring deleted IOS image

shelby_county · ‎01-08-2007

I purchased this switch on ebay, it does work (or at least it did before I deleted the files on it). I have followed the procedure to copy a file from via tftp and hyperterminal but get a permission denied error from hyperterminal and cannot connect from tftp.

I'm connecting via the console cable to a c2912-XL-EN, 8MB RAM. When I type dir flash: I get four options flash, null, bs and something else I can't remember (I'm at work, switch is at home). I know that there is a simple fix or way to proceed but just starting into this arean I need some assistance. Any advice is appreciated.

if you are unable to load a new IOS through HTTP or TFTP or CLI, you can load IOS through XMODEM in ROM monitor mode.

refer this link to get more information.

A senior network tech told me to try the following and it worked like a charm, but you have to be fast or you'll have to repeat the steps.

When you hit enter (after the copy

xmodem: flash:?? command), QUICKLY click

the ?transfer? pull-down menu & start the

xmodem transfer.

Also?. on SOME older Cisco devices the

command is ?copy xmodem: bootflash:

c2900xl-c3h2s-mz.120-5.WC16.bin?

Shelby,

Can you please paste the output of "dir flash:".

Let us know what prompt when you connect the console to the switch.
