ESM for CIsco2000
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
To perform a factory reset, password recovery of the ESM module or recover an ESM module with a corrupt software image on the CGR 2010.
Note: A direct connection to the CGR 2010 via console is required for this procedure to work.
Step 1. Connect to the CGR 2010 directly via console.
Step 2. Issue the command service-module gix/x/x reload to reload the ESM:
service-module gi0/0/0 reload
Step 3. As the ESM module is booting, use a pin to press the Express Setup (ES) button on the ESM module to break the boot sequence.
Step 4. Enter the ESM by issuing service-module gix/x/x session.
Step 5. Once in the switch: prompt, initialize flash: by issuing flash_init. After Step 5., follow the appropriate sections.
Step 10. Once in the CGR, use the copy command copy flash:<file from CGR2010> xmodem: to copy the new ESM image to xmodem.
cgr2010-ast03-lab#copy flash:test1 xmodem:test2
**** WARNING ****
x/ymodem is a slow transfer protocol limited to the current speed
settings of the auxiliary/console ports. The use of the auxiliary
port for this download is strongly recommended.
During the course of the download no exec input/output will be

Step 11. After the ESM image is copied to xmodem: successfully, log in to the ESM module.
service-module gigabitEthernet 0/0/0 session
Step 12. At the switch: prompt on the ESM, use the boot command to load the appropriate image.
Step 16. Enter n at the prompt to abort the initial configuration dialogue.
Enable secret warning
In order to access the device manager, an enable secret is required
If you enter the initial configuration dialog, you will be prompted for the enable secret
If you choose not to enter the intial configuration dialog, or if you exit setup without setting the enable secret,
please set an enable secret using the following CLI in configuration mode-
enable secret 0 <cleartext password>
Would you like to enter the initial configuration dialog? [yes/no]: no

Step 17. At the switch prompt, type en to enter enable mode.
Type rename flash:config.old flash:config.text to rename the configuration file with its original name.
Switch#rename flash:config.old flash:config.text
Step 19. Copy the configuration file into memory.
Switch#copy flash:config.text running-config
Step 20. Overwrite the current passwords.
Step 21. Copy current config with new passwords to startup-config.
