IP Address There are two modes to operate the HT–502:
DHCP mode: all the field values for the Static IP mode are not used (even

establish a PPPoE session if any of the PPPoE fields is set.
Static IP mode: configure the IP address, Subnet Mask, Default Router IP
address, DNS Server 1 (primary), DNS Server 2 (secondary) fields. These fields
are set to zero by default.
