The worst thing when starting a new job is when the previous Network Administrator left behind no documentation. How do you get into the devices? If you've been in this situation or just accidently mistyped your password, this article will hopefully shed some light on your problem.
 

1. Console to the device

Console into your switch using a console cable an a program such as HyperTerminal, CRT, SecureCRT or Putty.

2. Enter recovery mode

Unplug the power cable. Then, plug the power cable back in WHILE holding the mode button located on the front panel of the switch.

Note: For 2900/3500XL and 3550 Series switches, release the mode button after the LED above port 1 turns off. For 2950 Series switches, release the mode button after the STAT LED goes out.

3. Initialize the flash

 

switch: flash_init

Open in new window


4. Issue the load_helper command

 

switch: load_helper

jjmartineziii,
This appears to be substantially nothing more than the information already provided by Cisco:

Do you have anything further to add that they don't cover already?
