MAC address in the field provided. Be
sure to use the correct address format.
(The address must be entered in
hexadecimal format with no spaces
or dashes between the values.)
3. Click on OK to accept the MAC address change. Using the OK operation
disables automatic mode. This means that the system will not acquire or set
