What this means
The IEEE assigned the MA-L block FCE1FB to Array Networks. Every network interface they manufacture under this block has a MAC address beginning with these digits, followed by a unique per-device identifier. If a device on your network shows a MAC starting FC:E1:FB, it is Array Networks hardware.
