Power Indicator - This green indicator light is on when the Switch is receiving
power; otherwise, it is off.
Link/Act/Speed (1-8) - This LED indicator light is green when the port is
successfully connected to a 1000Mbps device and will blink as data is transmitted
or received.
This LED indicator light is amber when the port is successfully connected to a
100Mbps or 10Mbps device and will blink as data is transmitted or received.
PoE Ports (1-4) - This LED indicator light is solid green when the port is
successfully connected to a powered device and is powering the device
properly.
This LED indicator light is solid red when the PoE port has failed, possibly due
to PoE power circuit shortage, power is over the power current of the PoE
device's classification, or out of the PoE voltage output of 44 ~ 57 VDC.
If the LED is off, there is no connection to a powered device (that requires power).
PoE Max - A solid red light indicates the power output to PoE devices is over 45W.
No additional devices can be powered on safely. A blinking red light indicates that
the addition or removal of a device caused the power output to PoE devices to go
over 45W. The PoE MAX LED will blink for 2 minutes before changing to a solid red
light. When the light is off, the power output to PoE devices is less than 45W.
