NVIDIA ConnectX-5 InfiniBand/Ethernet Adapter Cards User Manual

Finding the GUID_MAC and Serial Number on the Adapter Card

Each NVIDIA adapter card has a different identifier printed on the label: serial number and the card MAC for the Ethernet protocol and the card GUID for the InfiniBand protocol. VPI cards have both a GUID and a MAC (derived from the GUID).

The product revisions indicated on the labels in the following figures do not necessarily represent the latest revisions of the cards.
