Reset CISCO 5505 ASA to Factory Default

You’ll need to use the Console Port to perform this proceedure.

Hook
up the blue console cable to your DB 9 PIN serial port. Plug the other
end into ‘Console’ port on the ASA 5505. The console port looks like a
network jack. It’s above the usb ports and is surrouned with a blue
color matching the console cable itself and says console right next to
the port.



Use hyperterminal, click Start, Programs, Accessories,
Communications, Hyperterminal, create a connection on Com1 using the
terminal settings:

- Bits per second: 9600
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None

After
you open your connection through hyperterm, press enter a couple times.
You should get a prompt similar to the following: ‘ciscoasa>’, or
‘nameofyourdevice>’
type ‘ena’ to go to enable mode. Enter the password, or just press enter if there is no password set.
type ‘config t’
type ‘config factory-default’
hit
spacebar when the ‘more’ is displayed to get the next page of output.
You want to get back to the prompt that looks like: ‘ciscoasa(config)#’
type ‘reload save-config noconfirm’

Make sure that the outside line is plugged into port zero, and your pc is plugged into any of the ports 1-7.

The
Cisco ASA has been reset to factory settings. DHCP is enabled on the
cisco device, and it’s internal IP address is now 192.168.1.1!
