hp Z220 duplicated Mac-Addresses (+50 devices)

[Nader_Lan]

I have more than 50 devices ( Z220 Workstation) and all of them with the same Mac-Address..!

What shall I do with this problem ?

All devices Are second hand

No one touched them yet..

NO Systems were installed yet

All devices show in the bios config screen that the Mac-Address is 88:88:88:88:87:88
