Cisco WS-X6724-SFP
Start the console session.
Plug in serial cable to device from PC COM1 port
Open PuTTY and select "Serial" connection type, leave baud rate (Speed) and other settings as default.
Plug power into device and if a power button exists, turn it on.
Access the Rommon prompt.
Press the Break key right after the route processor gains control of the console port, which is about 20-25 seconds after powering on. On the Catalyst 6500 that runs Cisco IOS, the switch processor boots first. The route processor has gained control of the console port when you see this message (do not initiate the break sequence until you see this message): Changing console ownership to route processor Example output:

TIP: If your keyboard does not have a Break key, in PuTTY right-click the titlebar for the dropdown menu -> Special Command -> Break.
Bypass any configured login.
Type the confreg command followed by a string value instruction to ignore the current configuration when booting up (due to a known bug you have about 10 seconds to do this before the device crashes):
rommon 1 > confreg 0x2142 You must reset or power cycle for new config to take effect
If the device did not crash, then type the reset command:
rommon 2 > reset System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 2006 by cisco Systems, Inc.

The boot process should bring you to an initial configuration dialog prompt. Type n then the Enter key, and Enter again when prompted to get started:
Would you like to enter the initial configuration dialog? [yes/no]: n Press RETURN to get started!
Erase any log files, vlan data and all configuration settings.
Type the enable command to enter privileged command mode, then the dir command, then the del command with * where necessary to match multiple filenames listed:
Router>enable Router#dir Directory of flash0:/ 1 -rw- 16958152 Oct 14 2008 00:38:54 +00:00 c1841-spservicesk9-mz.124- 8.bin 31932416 bytes total (14970880 bytes free)
Type the erase startup-config command, and confirm with y:
Router#erase startup-config Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]y[OK] Erase of nvram: complete
TIP: You can verify vlan data and configuration is gone with the show vlans and show startup-config commands respectively:

Copy all the output from the session into your records.
Right-click PuTTY's titlebar, from that dropdown menu click on "Copy All to Clipboard"
Open the file of record certifying the deconfiguration of this device and use CTRL V to paste all the output from PuTTY into that file. Formatting the text with a fixed-width font helps it look more readable.
End the session.
Turn off/unplug the device and close PuTTy.
