NVMe Switch Adapter

CAUTION!

Disconnect the computer from the power supply and from any networks to which you will install the adapter, or 
you risk damaging the system or experiencing electrical shock.

3.

Remove the cover from the chassis.

4.

Check the mounting bracket on the adapter.

 If required for your system, replace the full-profile mounting bracket that 

ships on the adapter with the low-profile bracket supplied. Complete the following steps to attach the low-profile bracket.

a. Using a No. 1 Phillips screwdriver that is ESD safe, remove the two Phillips screws that connect the full-profile 
bracket to the board. Unscrew the two screws located at the top and bottom edges of the board. Avoid touching any 
board components with the screwdriver or the bracket.
b. Remove the full-profile bracket. Do not damage the adapter.
c. Place the adapter on top of the low-profile bracket. Position the bracket so that the screw holes in the tabs align 
with the openings in the board.
d. Using a No. 1 Phillips torque screwdriver that is ESD safe, set to a maximum torque of 4.8 ± 0.5 inch-pounds. 
Replace the two Phillips screws removed in Step a.

ATTENTION:

Exceeding this torque specification can damage the board, connectors, or screws, and can void the warranty 
on the board.

ATTENTION:

Damage caused to the board as a result of changing the bracket can void the warranty on the board. Adapters 
returned without a bracket mounted on the board will be returned without return merchandise authorization 
(RMA) processing.

5.

Insert the adapter into an available PCIe slot.

 Locate an empty PCIe slot adequate for your adapter. Remove the blank 

bracket panel on the rear of the computer that aligns with the empty PCIe slot. Save this bracket screw, if applicable. 
Align the adapter to a PCIe slot. Press down gently, but firmly, to seat the adapter correctly in the slot. The following figure 
shows how to insert the adapter into a PCIe slot.

NOTE:

The shape, size, and locations of the components on your adapter and its bracket might vary from this illustration.

6.

Make sure the system provides the required airflow for the adapter.
