1. Connect your PC(USB) to the switch(RJ45) using a console cable.
2. Open a terminal emulator like Putty and use the settings below.
   Baud rate: 9600
   Data bits: 8
   Stop bits: 1
   Parity: None
   Flow control: None
3. Unplug and plug the power cable from the switch.
4. Press the control + C keys to break the boot process. Or ask the local IT onsite to press the mode button 2-3 times.
5. Once on the ROMMON mode, type switch: SWITCH_IGNORE_STARTUP_CFG=1 as shown below.
6. Boot the switch with the packages.conf file from flash: switch: boot flash:packages.conf
7. Terminate the initial configuration dialog by answering No: Would you like to enter the initial configuration dialog? yes/no: No
8. At the switch prompt, enter privileged EXEC mode.
9. Copy startup-config running-config.
    Switch# copy startup-config running-config
10. Change the enable password.
     Switch(config)# enable secret cisco
11. Save the config.
     Switch# copy running-config startup-config
12. Set the SWITCH_IGNORE_STARTUP_CFG parameter to 0.
      Switch(config)# no system ignore startupconfig switch all
13. Verify that SWITCH_IGNORE_STARTUP_CFG is set to 0.
     Switch# show romvar | inc SWITCH
     AUTO_SWITCH_CONSOLE_DISABLE=0
     SWITCH_DISABLE_PASSWORD_RECOVERY=0
     SWITCH_IGNORE_STARTUP_CFG=0
     SWITCH_NUMBER=1
     SWITCH_PRIORITY=15
14. Reload the device.
      Switch# reload
15. Verify that the ports are all up and running. If they are NOT, enable all of them.
16. Verify that the config register is set to 0x102, not 0x142, which ignores the startup configuration.
17. You’re done!
