Warnings & Notices

• 

The circuit boards within the product are sus-
ceptible to static electricity. Proper grounding 
is strongly recommended to prevent electrical 
damage to the product or other connected 
devices, including the computer host. 

• 

Avoid placing the adapter close to magnetic 
devices, high voltage devices, or near a heat 
source. This includes any place where the 
product will be subject to direct sunlight. Do not 
allow water to make contact with the adapter.

• 

Before starting any type of hardware installa-
tion, please ensure that all power switches have 
been turned off and all power cords have been 
disconnected to prevent personal injury and 
damage to the hardware. 

• 

When unplugging cables, 

always

 squeeze 

the cable’s overmold (if it has one) to release 
the connector latches before unplugging the 
cable. Failure to do so may result in damage the 
latches on the cable and prevent it from latching 
securely in the future.

• 

The cable you use to connect a device to the 
SFF-8612 connector on the adapter requires 
85

Ω

 impedence for PCIe/NVMe compatibility.
