Using Recovery Procedures
After the switch performs POST, the switch begins the autoboot process. The boot loader prompts the
user for a break key character during the boot-up sequence, as shown in this example:
***** The system will autoboot in 15 seconds *****
Send a break key to prevent autobooting.
Step 4 When the boot loader prompts you, enter the break key.
The following example displays the messages that appear on the console after the user enters a break key:
The system has been interrupted prior to initializing the flash file system.
The following commands will initialize the flash file system, and finish loading
the operating system software:
flash_init
load_helper
boot
After a the message diplays, the boot loader prompt resumes.
On the Catalyst 2955C-12 and Catalyst 2955S-12, the PORT 13 LED flashes green and the PORT 14
LED is off during the initial appearance of the boot loader prompt on the console. On the
Catalyst 2955T-12, the PORT 1 LED flashes green and the PORT 2 LED is off during the initial
appearance of the boot loader prompt on the console.
Step 5 Initialize the Flash file system:
switch# flash_init
Step 6 If you 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
7741440 bytes total (3884509 bytes free)
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
