The following illustration shows the major components in the server.
Blue on a component indicates touch points, where you can grip the component to remove it from or install it in the server, open or close a latch, and so on.
Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.
