There are three types of serial numbers that can be found on Xircom® Ethernet cards.
1. Alphanumeric 12-character serial number (mainly found on new products, particularly the RealPort and CompactFlash cards), for example 9001H100AB73:
a. Take the last six digits of the card and add Xircom's company code to the front. Xircom's company code is 0010A4.
b. You should have 0010A4 + 00AB73 = 0010A400AB73
b. The MAC address for this example would be 00-10-A4-00-AB-73.
Note: For the next two types of serial numbers, you must to convert from decimal to hexadecimal using a scientific calculator).
2. Alphanumeric 7-character serial number, for example C474918:
a. Replace the first letter with its hexadecimal equivalent.
b. You should have 12+474918 = 12474918.
c. Convert it to hexadecimal. You should have 12474918 = BE5A26.
d. Switch the last two characters with the first two characters. 265ABE.
e. Add the Xircom MAC identity code to the front. Xircom's MAC identity code is 0080C7. You should have 0080C7 + 265ABE = 0080C7265ABE.
f. The MAC address for this example would be 00-80-C7-26-5A-BE.
3. Numeric 7-digit serial number, for example 9901718:
a. Convert the serial number to hexadecimal. You should have 971696.
b. Switch the last two digits with the first two digits. You should have 961697.
c. Add the Xircom MAC identity code to the front. Xircom's MAC identity code is 0080C7. You should have 0080C7 + 961697 = 0080C7961697.
d. The MAC address for this example would be 00-80-C7-96-16-97.
