It would also be good to seperate CAN-related LEDs and Bootloader-related.

Leave status where it is right now, and move closer to the bottom, in a single row, in this order:

• Power (red)
• Terminated (orange)
• Traffic (green)

"Enable" is actually putting the switch in the downwards position, so the "Enable" on the top case is very confusing in this regard.

If possible, change the switch to one that doesn't have the ON/1 print.

But, the print on the top case should def be changed to OFF/ON to make it clear that the downward position is what turns on the CAN bus.
