On all of the 3com boards I have seen in the U.S. the Ethernet address is
located on the board in two places.

On the back of the board, there is a label in English that specifies the
"NETWORK ADDRESS". This number has two parts; an assigned prefix that
identifies the interface as being manufactured by 3com, and a unique part
that identifies the specific board.  

This second part of the address is also located on the small prom chip that
encodes the address. On a 3c505 card the first part of the address is 02.60.8C
and the prom is at U17. A 3c503 card will have a similar set of lables.

If the system is up and running you can find out the Ethernet address by using
the arp command available under UNIX.
