Excel Formula to Convert Polycom 8020/8440 Serial Number to MAC Address

This is an obscure tip, but it thought it was cool enough to post as it comes in handy when scanning in inventory with a barcode scanner. This works on Polycom 8400’s (8440/8450) and 8000’s (8020/8002)., and probably any other Polycom SIP device.

This formula will take the serial number in the column to the left and convert it to a MAC address.
