Using Recovery Procedures
Step 3 Unplug the switch power cord.
Step 4 Press the Mode button, and at the same time, reconnect the power cord to the switch.
You can release the Mode button a second or two after the LED above port 1X goes off. Several lines of
information about the software appear, as do instructions:
The system has been interrupted prior to initializing the flash file system. These
commands will initialize the flash file system, and finish loading the operating system
software:
flash_init
load_helper
boot
Step 5 Initialize the Flash file system:
switch# flash_init
Step 6 If you had set the console port speed to anything other than 9600, it has been reset to that particular
speed. Change the emulation software line speed to match that of the switch console port.
Step 7 Load any helper files:
switch# load_helper
Step 8 Display the contents of Flash memory as in this example:
switch# dir flash:
The switch file system is displayed:
Directory of flash:/
3 drwx 10176 Mar 01 2001 00:04:34 html
6 -rwx 2343 Mar 01 2001 03:18:16 config.text
171 -rwx 1667997 Mar 01 2001 00:02:39 c2950-i6q412-mz.121-9.EA1.bin
7 -rwx 3060 Mar 01 2001 00:14:20 vlan.dat
172 -rwx 100 Mar 01 2001 00:02:54 env_vars

Step 9 Rename the configuration file to config.text.old.
This file contains the password definition.
switch# rename flash:config.text flash:config.text.old
Step 10 Boot the system:
switch# boot
You are prompted to start the setup program. Enter N at the prompt:
Continue with the configuration dialog? [yes/no]: N
Step 11 At the switch prompt, change to privileged EXEC mode:
switch> enable
Step 12 Rename the configuration file to its original name:
switch# rename flash:config.text.old flash:config.text
