This button is used for these purposes:
■ Deleting Passwords - When pressed by itself for at least one second, the
button deletes any switch console access passwords that you may have
configured. Use this feature if you have misplaced the password and need
console access.
This button is provided for your convenience, but its presence means that
if you are concerned with the security of the switch configuration and
operation, you should make sure the switch is installed in a secure
location, such as a locked wiring closet.
■ Restoring Factory Default Configuration - When pressed with the
Reset button in a specific pattern, any configuration changes you may
have made through the switch console, the web browser interface, and
SNMP management are removed, and the factory default configuration is
restored to the switch. For the specific method to restore the factory
default configuration, see “Restoring the Factory Default Configuration”
on page 11, in chapter 4, “Troubleshooting” of this manual.
