Some ports in a 2 switch 2960x stack are showing down. The stack is cabled as the pic below. Any idea why the ports are showing down? The IOS versions are the same.
Switch#sh sw de
Switch/Stack Mac Address : 70d3.79b2.1780
H/W Current
Switch# Role Mac Address Priority Version State
----------------------------------------------------------
*1 Master 70d3.79b2.1780 15 4 Ready
2 Member cc8e.719d.fa00 1 4 Ready
Stack Port Status Neighbors
Switch# Port 1 Port 2 Port 1 Port 2

##sh switch neighbor

Hello
Most probably faulty stack cable or it isnt attached correctly, Remove it and reset the cable, also make sure the stack port is actually enabled.
switch x stack port x enable
