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.
The illustrations in the following sections show the connectors, LEDs, and jumpers
on the system board. In addition, illustrations of the connectors and LEDs on the
optional microprocessor and memory expansion tray and the PCIe riser card.
