Booting from the Recovery Partition Cisco Catalyst 9200CX Series Switches support booting from the recovery partition. This is beneficial to end users if they face an issue while trying to boot the switch from Flash or an external device, such as USB or SDflash. The recovery image is the same as the recommended Cisco IOS image for the switch, and is stored in a partition named drec0 . You can not access recovery partition when the switch is in Cisco IOS prompt. Note that the factory-reset process does not erase this image. Note To check the partition image name, enter dir drec0: switch: dir drec0:

These recovery procedures require that you have physical access to the switch. Note On these switches, a system administrator can disable some of the functionality of this feature by allowing an end user to reset a password only by agreeing to return to the default configuration.
If you are an end user trying to reset a password when password recovery has been disabled, a status message shows this during the recovery process. Procedure Step 1 Connect a terminal or PC to the switch. • Connect a terminal or a PC with terminal-emulation software to the switch console port. • Connect a PC to the Ethernet management port.
