3.3 Cavium Ethernet
The Ethernet address for your board is a unique identifier on a network. The address consists of
48 bits (MAC [47:0]) divided into two equal parts. The upper 24 bits define a unique identifier
that has been assigned to Artesyn Embedded Technologies - Embedded Computing by IEEE.
The lower 24 bits are defined by Artesyn for identification of each of our products.
The Ethernet address for the ATCA-9305 is a binary number referenced as 12 hexadecimal
digits separated into pairs, with each pair representing eight bits. The address assigned to the
ATCA-9305 has the following form:
00 80 F9 xx yy zz
00 80 F9 is Artesyn’s identifier. The last three bytes of the Ethernet address consist of the port
(one byte); 0x99(SPI 1), 0x9A (SPI 2), 0x9B (SPI 3), or 0x9C (SPI 4), followed by the serial
number (two byte hexadecimal). The ATCA-9305 Cavium has been assigned the Ethernet
address range 00:80:F9:99:00:00 to 00:80:F9:9C:FF:FF. The format is shown in
Table 3-4 .
