Each stacking port has one link LED labelled LINK/ACT.

Figure 17. Stacking Port S1 and S2 LEDs

The stacking port LED is described in Table 15.

The stacking port LEDs do not indicate packet activity.

The Stack ID LED, shown in Figure 18 on page 52, displays the ID number 
of the switch. A stand-alone switch should have the ID number 0. Switches 
connected with the stacking ports to form a virtual stack must have unique 
numbers. Chapter 5, “Powering On the Switch” on page 85 has the 
procedure for verifying and, if necessary, changing the ID number of the 
switch.
