In the MicroZed Hardware guide it is written:
"When used as a production SOM, it is recommended that D4 be de-populated and D9 be replaced with a shunt."
Now, since I'm not a native English speaker, I had a look in my dictionary for "shunt" and it tells me that this is a small resistor. So I'm supposed to replace D9 with a resistor? Then how big should that resistor be? Or would it be OK if I just directly wire the two contacts for D9.
