Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.
Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding systems.
Procedure
Touch the static-protective package that contains the M.2 cage to any unpainted surface on the outside of the server. Then, take the M.2 cage out of the package and place it on a static-protective surface.
Install the M.2 cage.
Figure 1. M.2 cage installation
Slide the cage to the direction as shown to align the cage with pins on the chassis.
Tighten the screw and make sure that the cage is secured in place.
Connect the cables routed through the clips on the M.2 cage. For more details, see Internal cable routing.
