LED Mode Select Button and Indicator LEDs
To optimize the amount of information that can be displayed for each of the
switch ports, the 5400R zl2 switches use a Mode LED for each port. The
operation of this LED is controlled by the LED Mode Select button on the
switch chassis, and the current selection is indicated by the mode indicator
LEDs near the button. Press the button to change from one mode to the next.

■
If the Activity indicator LED is lit, each port Mode LED displays
activity information for the port—it flickers faster for the higher traffic
rates.
■ If the Full Duplex indicator LED is lit, the port Mode LEDs light for
those ports that are operating in full duplex.
■
If the speed indicator LED is lit, the port LEDs behave as follows to
indicate the connection speed for the port:
• Off = 10 Mbps or 100 Mbps
• Blinking = 1 Gbps (the blinking behavior is a repeated on/off cycle
once every 0.5 sec.)
• On = Faster than 1 Gbps
