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.
1 | Mode LEDs (one for each port) |
2 | LED Mode Select button and indicator LEDs |
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
For 10/100/1000BASE-T, SFP and SFP+ Ports:
Off = 10 Mbps or 100 Mbps
Flashing = 1 Gbps
On = >1 Gbps
For HPE Smart Rate ports:
Off = Not linked
Slow Flash = 1 Gbps
Double Flash = 2.5 Gbps
Triple Flash = 5 Gbps
On = 10 Gbps
For QSFP+ ports:
Off = Not linked
Fast Flash = 40 Gbps
For more information on HPE Smart Rate port LEDs and 40 G ports in speed mode, see HPE Switch v3 zl2 module installation guide.
If the PoE indicator LED 
is lit, the Link and Mode LEDs
indicate PoE status:
Link LED:
On = PoE is enabled on this port
Off = PoE is disabled on this port.
Slow Blinking Orange = Internal PoE fault on this port.
Fast Blinking Orange = This port is denied PoE power or has an external load fault.
Mode LED:
On = PoE power is be supplied on this port
Off = PoE is not being supplied on this port.
