Hardware Overview 95
Port and System LEDs
The front panel contains light emitting diodes (LEDs) that indicate the
status of port links, power supplies, fans, stacking, and the overall system
status. See "N2000 LED Definitions" on page 97 for more information.
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 illuminated, and the unit number is displayed.
