Workstation label locations
In general, the serial number labels can be found on the top panel or on the side of the workstation
and at the rear of the workstation (your workstation may look different). Keep this number available
when contacting customer service for assistance.
A product number is generally located next to the serial number.
The COA is used for Windows-preinstalled systems only and is generally located on the top panel or
side of the workstation near the serial number label. On some workstations, it is located on the bottom
of the workstation.
