Ethernet MAC Addresses
Single-Port Adapters
The Ethernet address should be printed on the identification sticker on the front of the card.
Multi-Port Adapters
Dual port adapters have two Ethernet addresses. The address for the first port (port A or 1) is printed on a label on the
component side of the adapter. Add one to this address to obtain the value for the second port (port B or 2).
In other words:
l Port A = X (where X is the last numeric of the address printed on the label)
l Port B = X + 1
