So your EEPROM programmer/contents should look like this:ĮEPROM Unlock Strings FCX Advanced Routing Note: These are raw HEX bytes (not ASCII) to be written starting at the beginning of the EEPROM. You can also buy a cheap EEPROM Programmer - see the EEPROM Programmer guide at the bottom of this page. They will take 3 to 4 weeks to arrive, but they work.įor programming the strings into the EEPROM, it's possible to do it from the v7 bootloaders with the i2cWriteByte command, but it involves multiple commands.
All US vendors I could find are out of these as they are old, this is the only place I could find to order some. They need to be AT24C164 chips, the later revision 24LC16B will not work. If the switch didn't come with a blank EEPROM already in the socket, you need to purchase one. Some devices shipped with a blank EEPROM already in the slot that you can program from the bootloader, others came with none. Then the second optional EEPROM in a removable socket: this is the EEPROM that contains the magic string. Note: All FastIron devices had two EEPROMs - a soldered in main EEPROM that contained chassis data like MAC address, serial number, manufacture date, etc.
I am providing the strings here to give these old pieces of hardware a little more life. These products are now very old, have not been sold for a decade, and the below license EEPROMs are impossible to buy as the company no longer exists (Foundry is gone).
The EEPROM would contain a magic string of letters and numbers, and when the switch OS saw this it knew to unlock said features. These were either installed from factory, or you could purchase them and install them yourself.
