The colors of component labels indicate different types of components.
A blue label on a component or near 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.
An orange label on a component or near a component indicates that the component can be hot-swapped. This indicates that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running.
Use the IBM® System x3850 M2 and x3950 M2 Types 7141, 7233, 7144, and 7234 Problem Determination and Service Guide 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.
