DETAILED STEPS

Command or Action Purpose

Step1 service-module interface slot/port session

Example:

Router# service-module gigabitethernet1/0 session

Connects to the service module and opens a Cisco

EtherSwitch service module session.

Step2 dir flash:

Example:

rommon> dir flash:

Displays a list of all files and directories in flash

memory on the service module.

Step3 service-module interface slot/port password-reset

Example:

Router# service-module gigabitethernet1/0

password-reset

Enables password recovery.

Step4 flash_init

Example:

Switch: flash_init

Initializes the flash memory file system.

Step5 load_helper filesystem:/file-url ...

Example:

Switch: load_helper flash:xyz

Loads and initializes one or more helper images.
