Removing and Replacing the Server Top Cover
To remove or replace the top cover of the server, follow these steps:
Tip You do not have to remove the cover to replace hard drives or the power supply.
Step 1 Remove the top cover (see Figure 3-3):
a. Loosen the captive thumbscrew screw that secures the rear edge of the cover to the chassis.
b. Push the cover toward the server rear about one-half inch (1.27 cm), until it stops.
c. Lift the cover straight up from the server and set it aside.
Step 2 Replace the top cover:
a. Place the cover on top of the server about one-half inch (1.27 cm) behind the lip of the front chassis
panel. The cover should sit flat.
Note The flanges on the top cover must slide underneath the front chassis panel.
b. Slide the top cover toward the front chassis panel, sliding the flanges on the top cover underneath
the front chassis panel.
c. Tighten the captive thumbscrew that secures the rear edge of the cover to the chassis.
