3.6.4 Set DNS Server IP Address
The DNS server allows the name of a remote machine to be resolved automatically. Enter the IP address of
the DNS server. If the device is DHCP enabled, the DHCP server provides the DNS server IP address,
which will override this configured value.
Note: This setting is applicable only in Manual Connection mode.
3.6.5 Change Telnet configuration password
Setting the Telnet configuration password prevents unauthorized access of the setup menu via a Telnet
connection to port 9999 or through Web pages. The password is limited to 4 characters. An enhanced
password setting of 16 characters is available under Security Settings for Telnet access only.
