Hi, 
For zyxel switches, why Are There 2 Triangle Light Indicators For Every Port?
I understand that those pointing to the top refers to the interface on top.
I understand that those pointing to the bottom refers to the interface on bottom.
But why 2 triangles for each interface?

    Hi,
    In the circled portion, there are 2 triangles up and 2 triangles down.
    I notice that when the interface is up, only 1 triangle will light up.
    What is the other triangle for?
