There are a number of different labels on the IPA card

The two main labels are

a) Serial number : this can be found on a silver label (see Green Arrow)

See these FAQs

Serial Number Lookup for Warranty Eligibility

Service: Is there a way to identify the age of a Clear-Com product by its serial number

b) mDNS (Host IP name) : This can found on the board, (see Red Arrow)

The mDNS name is used to help auto-discover the IPA card on the network by the Eclipse frame and/or IP networking tools and is also used to access the IPA’s CCM (on board web browser).
