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 (in
other words, it is a stack of one switch), the M LED is lit, and the unit number displays.
