You can "erase start" from previliged mode and restart the switch. It will bootup with default config.
thanks for ur reply,
I wrote "erase start" on EXEC mode then I entered "reload". After that switch's SYST link has been flushing(green) for 5 minutes, I dont understand what's wrong, I have unpluged and pluged the power cord, but syst link is still flushing and the switch does not work:( could u tell me what to do?
What does the console say? What output do you have on the console/ Is it stuck in ROMMON or something? Can you paste the consoe output?
I think I am stuck in ROMMON but I am not sure, when I connect the switch with console port, only "switch:" is written on the console.
when "?" is entered those output comes

when I unplug the power cord then I push the mode button and plug the power cord, after a certain time this output is appeared

the flash filesystem, and finish loading the operating
I have never seen this commands before, could u tell me the next step?
On the switch prompt, say dir flash:
if you see the ios image there, say boot flash:
this should boot it up.
For more info pls refer :
Hope this helps (pl rate if it does)
if the switch is stuck in "Rommon " mode when you see through the console, probably it is not finding the boot image. See with dir slot0: or dir bootdisk: and once you get the image name, say boot bootdisk: or boot slot0:imagename depending on where the image is located.
switch: dir slot0
unable to stat slot0/: no such device
List of filesystems currently registered:
switch: boot bootdisk:flash (and tried with xmodem and null)
Loading "bootdisk:flash"...bootdisk:flash: no such device
Error loading "bootdisk:flash"
Interrupt within 5 seconds to abort boot process.
Boot process failed...
switch: help boot
Usage for "boot" is:
boot [-n|-j] [-p] [-c] [-f] [-i] [-m] [-notnd] [-notni] [-post] [-skip_post]
[-reserve_mem <1-15>] [-no_esp_keepalive] [
I dont know what to do now, could u tell me what should I do ?
thank u so much for your helps
Do a "dir flash: and see if there is any image in there. If there is issue a "boot flash:
I did it
switch: dir flash:
Directory of flash:/
32513024 bytes available (1024 bytes used)
there is no any image file. so what do I have to do ? I think I need to download 2960 IOS and load to switch, do u know where can I download 2960 IOS
You woul need a cisco.com login to download the image from under "software downloads" on the cisco main page.
