3. Place hard drive in the tray and fix HDD with the hard drive mounting screws. After that,
put the tray with HDD back to the NA762A-G3 enclosure. Repeat the procedure to
complete the rest of the trays with hard drives.
4. Install PCIe 3.0 ×4 host adapter card into one available PCIe slot in the host computer.
The tower Mac Pro (2019) or Windows PC must have at least one available PCIe slot (×4, ×8
or ×16); the slot could be PCIe ×4 electrically even if its physical appearance is PCIe ×8 or
×16, so please check the user’s manual of tower Mac Pro or PC motherboard to verify the
specification of the PCIe slot.

5. Connect NA762A-G3 and host computer with external PCIe 3.0 ×4 data cable, and then
connect the storage with power source.
※Note the ring-pull of the external PCIe ×4 data cable connector must be at the same side
as Nestor host card’s obverse side when cable is connected to the NP963AG3 host card.
Also, when inserting the PCIe ×4 data cable into NA762A-G3 storage’s rear port, the
ring-pull of the cable must face upward.
