When provisioning the modem, the Cable service provider may request the HFC MAC ID of the modem.  The label on the bottom of the SB6141 contains the Media Access Control (MAC) address, a unique, 48-bit value permanently saved in ROM at the factory to identify each Ethernet network device.  To receive data service, the MAC address marked HFC MAC ID will need to be provided to the Internet Service Provider. The HFC MAC ID is also known as the CMAC Address. This document includes the following sections:
Locating the MAC ID on the Bottom Panel
The MAC ID can be located on a white sticker on the bottom of the device.

Locating the MAC ID in the GUI
NOTE: If the SB6141 is connected to a router, it is recommended to disconnect the router and connect the SB6141 directly to a computer with an Ethernet cable.
