Each AMC13 has a hardware serial number determined by solder jumpers on the T2 board (8 bits). This number determines the MAC address, and is therefore defined as the module serial number, and should be printed visibly on the front panel and on the T3 board.

Every AMC13 consists of a stack of 3 boards, numbered T1, T2, T3 with T1 being the right-most board when the module is oriented as it is installed in the crate. Each board has a serial number for book-keeping purposes, but only the T2 board's serial number is electrically significant.

Each board has a label attached which looks like one of the examples below. These are QR codes which may be scanned with an app on most smart phones, and decode to a URL such as http://db.amc13.info/B.cgi?A0054 for the label on the right. The URL should connect to a database with board information on the AMC13 web site.

The serial numbers for the 3 boards and the module are all different, though the last 3 digits may match when the modules are first assembled. The label with the "SN-xxxx" is the module serial number and and should be used to report problems or for inventory purposes.

The details of the label marking and URL are given below.
