How is the Commander's Single Board Computer (SBC) labeled on the back of the Commander site controller?

The Commander's Single Board Computer (SBC) is labeled as "A" on the back of the Commander site controller. This labeling is utilized for easy identification and ensures that technicians and users can quickly locate the SBC when performing maintenance or troubleshooting tasks. By standardizing the labeling, it helps reduce confusion in environments that may have multiple controllers or components, streamlining the process and ensuring effective communication among team members who are handling the site controller. The other labels may denote different components or serve other purposes within the system, which is why "A" specifically identifies the SBC.
