[This Figure, callout 34]

The M.2 SATA interface is provided for SATA SSD access using the PS-side bank 505 GTR transceiver. This Figure shows M.2 connector U40.

The socket 2 SATA adapter pinout with key M is shown in Table: M.2 Connector U40 Pinout. SATA-A data connection is used for TX and SATA-B for RX. The M.2 connector U40 is a type 2242 (active component section 22 mm wide with overall length 42 mm form factor) used on socket 2.
