Stack Master LED and Stack Number Display
When a switch within a stack is the master unit, the stack master LED, which
is labeled M, is solid green. If the M LED is off, the stack member is not the
master unit. The Stack No. panel displays the unit number for the stack
member. If a switch is not part of a stack, the M LED is illuminated and the
stack unit number is 1.
