Components Used

The information in this document is based on the hardware version below.

• Cisco AS5200 Series Router

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Look for a Valid Image in Flash:

Follow the instructions provided below:

1. Issue the dev command to see which devices and Flash files are available on your router:

   rommon 1 > dev
   Devices in device table: 
           id  name
       flash:  flash
   bootflash:  boot flash
       eprom:  eprom 

2. Issue the dir flash: command and look for a valid Cisco IOS® software image:

   rommon 2 > dir flash: 
            File size           Checksum   File name 
      7452688 bytes (0x71b810)   0x1f76    c5200-is-l.120-11.bin 

3. Try to boot from that image.

   • If the file is valid, this brings you back to normal operation mode.

     rommon 3 > boot flash:c5200-is-l.120-11.bin 
     program load complete, entry point: 0x22000060, size: 0x71b7f0 
     ... 

   • If none of the files are valid, you need to download a new one using one of the following procedures:

     • Download using the Boot Image and a Trivial File Transfer Protocol (TFTP) Server

       See How to Upgrade from ROMmon Using the Boot Image for the detailed instructions.

     • Download Using Xmodem from ROMmon

       You can also download a new Cisco IOS software image directly from the ROM monitor (ROMmon) through the console port, using Xmodem.

       See Xmodem Console Download Procedure Using ROMmon for the step-by-step procedure.
