Interpreting Electronic Serial Number (ESN)

Module labels contain a product serial number that could be significant in your dealings with

Cambium or your supply chain. This is the electronic serial number (ESN), also known as the

Media Access Control (MAC) address, of the module. This hexadecimal number identifies the

module in

• communications between modules.

• the data that modules store about each other (for example, in the Registered To field).

• the data that the BAM software applies to manage authentication and bandwidth.

• Prizm auto discovery of SMs through the AP (or BHS through the BHM).

• software upgrades performed by CNUT.

• information that CNUT passes to external tools.
