Figure 1. AT-iMG646xx Series Intelligent Multiservice Gateway

The MAC address(es) for the AT-iMG646xx gateway are located on the
label above the RJ11 and RJ45 ports.
The AT-iMG646BD-ON has a single MAC address. The
AT-iMG646PX-ON gateway has two MAC addresses, one for the GEPON
WAN uplink (GEPON WAN MAC or GEPON MAC), and the other for the
AT-iMG646PX-ON gateway itself (Ethernet iMG MAC or iMG MAC). When
the AT-iMG646PX-ON is initially registered, the OLT tries to register the
unit based on the GEPON WAN MAC address. After registration, the
network configuration is loaded against the AT-iMG646PX-ON MAC
address.
