Develop an end-to-end hypothetical reference model, network architectures, precision time tools, performance objectives and the methods to distribute, operate, monitor time synchronization within data center and much more...
This is a good catch. I corrected these issues in V8. I'll close this issue after uploading V8, please re-open if there are any other issues. Thank you!

The new status LED driver, U6, on sheet 2 of the new schematic has pin 1 ("SDB") pulled to ground through a 100K resistor.
The data sheet description of this pin reads: "Shutdown the chip when pulled low". That would render the driver and LED's useless.
Also, the pulldown is bypass by a 0.1 uF cap. Why?
