5 Removing and replacing components
Operating the server for more than 2 minutes with the top cover removed might damage
server components. For proper cooling and airflow, replace the top cover before you turn on
the server.
To remove the top cover, complete the following steps.
Step 1 Read the safety information and "Installation guidelines".
Step 2 If you are installing or replacing a non-hot-swap component, turn off the server and all
peripheral devices, and disconnect the power cords and all external cables.
Step 3 Slide the server out of the rack until the slide rails lock into place.

13 mm (0.5 inch). Lift the cover off the server.
