rear half of the top cover open.

cover.
8. Place your hands on the sides of the chassis near the hinge of the rear part such that your
thumbs can aggressively slide the entire top cover toward the rear of the chassis. Sliding the
cover in this direction disengages the hooks on both sides of the top cover from the chassis
housing.

Installing the Top Cover

To replace the cover, complete these steps:
1. Provide ESD protection by wearing an antistatic wrist strap attached to chassis ground of the
system when handling components.
2. Before installing the top cover, check that you have not left loose tools or parts inside the
system.
3. Check that cables, add-in boards, and other components are properly installed.
4. Make sure that the 120 mm fan cover is lifted and open.
5. Fold the rear part of the top cover open and set it down on the chassis, aligning the hooks on
both sides of the front half of the cover.
6. Place your hands on the sides of the chassis near the hinge of the rear part such that your
thumbs can aggressively slide the entire top cover toward the front of the chassis. Sliding the
cover in this direction engages the hooks on both sides of the top cover into the chassis
housing.
7. Close the 120 mm fan cover and tighten the thumbscrew. If the door does not close then the
top cover hooks have not fully engaged into the chassis.
8. Replace the PCI adapter board cover and install the screw that secures it to the top cover.
9. Close the rear half of the top cover and tighten the two thumbscrews.
10. Push the chassis back into the rack.
