Figure 13. Server components for 5U server models with hot-swap power supplies
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.
