Deleted flash directory on Cisco 3550

[hander2020]

Dear all: 

Unfortunately I deleted the flash directory on my Cisco switch 3550, when I reboot the switch I realized that there is no IOS at all.

any way to restore the IOS from local directory ? 

If not , how I could running back the switch

Issue the following commands:

1) flash_init

2) load_helper

Next you need to change the baud rate on the switch, otherwise it will take about 2 hours to transfer the IOS via xmodem.

3) set BAUD 115200

After you issue the baud rate command on the switch make sure you also change it in Hyperterminal or whatever software terminal emulation software you use. Otherwise you won't be able to communicate to the switch.

4) copy xmodem:"image_filename.bin" flash:"image_filename.bin"

5) In Hyperterminal or SecureCRT  select "Transfer" and select "send file". Change the protocol to xmodem. Next select browse and navigate to where you have stored the IOS that you would like to transfer to the switch. Click send.

The transfer will take about 20-40 minutes.

6)boot flash:"image_filename.bin"

DONE

Another option is to load the ios via tftp from ROMMON.

Here is a posting that discusses this option.
