Lenovo THINKSERVER 3821 - Manual (Page 158)

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.
Opening the bezel
Important: Before you install optional hardware, make sure that the server is
working correctly. If an operating system is installed, start the server, and make
sure that the operating system starts. If no operating system is installed, start the
server and make sure that a 19990305 error code is displayed, indicating that an
operating system was not found but the server is otherwise working correctly. If the
server is not working correctly, see the Chapter 5, “Diagnostics,” on page 27 for
diagnostic information.
The following illustration shows how to open the bezel.
