If you do not want to reset to factory-default settings and lose your configuration,
reboot the security appliance and use a packet sniffer (such as Ethereal™) to
capture packets sent during the reboot. Look at the ARP packets to locate the LAN
interface address.
STEP 5 Launch your web browser and ensure that Java, JavaScript, or ActiveX is enabled.
If you are using Internet Explorer, click Refresh to ensure that the Java applet is
loaded. Close the browser and launch it again.
STEP 6 Ensure that you are using the correct login information. The factory default login
name is cisco and the password is cisco. Ensure that CAPS LOCK is off when
entering this information.

configuration.
