About 30Mbps Units

My company bout a 30Mbps 5700BH that i successfully installed for a customer 8 months ago. Recently one had a problem and we have to send it to motorola for repairs; We got another one for replacement for now. I would like to know whether someone has installed 30Mbps Bh that did not come together? I am asking this due to License key problem. When Motorola send the pair, it factory preconfigured (master-slave, mac add license key)
I need assistance

You should only need to match the mac addresses in the configuration screen. There isnt a need to get a new license.
