Removing the COA
In the event that you need to RMA your module, make sure that you retain the original Certificate of
Authenticity (COA) label. The COA is the label from Microsoft with the code that enables their
windows software. After you return the module, Cisco Systems cannot retrieve the COA label from the
returned module.
The COA label is attached to the inside half of a plastic pull out label tray. To remove the COA label,
cut away half of the label that contains the COA label and save it. Return the unit with the other half of
the label tray that contains the units CLEI code, Serial Number, and other important unit labels back to
Cisco Systems or your licensed reseller.
