c. Place the PCIe riser upside down on an ESD surface.
d. Remove the screw and the tail-stock filler for that position.
e. If you are inserting a storage drive adapter, connect the signal cables to the adapter before
inserting the adapter. See "Drive installation details for the 8001-12C system" on page 8 for cabling
information.
NVMe drives are only supported on host operating systems; NVMe drives are not supported by
guest operating systems. On systems with RHEL 7.3 or later, or Ubuntu 16.04 or later, NVMe
drives can be used as bootable drives. Port 1 of the internal NVMe host bus adapter must be
plugged into NVMe port 1 on the disk drive backplane.
f. Insert the adapter (A) into the riser (B) as shown in Figure 47, aligning it properly and inserting it
fully into the slot. Secure the adapter tail-stock with 1 or 2 screws as needed.
