10/100BASE-TX Autosensing Ethernet Port Status LED

There are two port status LEDs on both sides (yellow LED on the left and green LED on the right) of the 10/100BASE-TX Ethernet port on the Switch 4210 PWR models. They indicate the port’s active, link, duplex, and speed status.

In addition, there is an A/L LED and a D/S LED on each Switch 4210 PWR model. These two LEDs indicate the port status LEDs mode. When the A/L LED is on, the port status LEDs respectively indicate the port’s active status and link status. When the D/S LED is on, the port status LEDs respectively indicate the port’s duplex status and speed status. Either the A/L LED or the D/S LED is on at one time. For details, see Table 4.

The A/L LED is	Yellow LED	BLINKING	The port is in the active state and there is

		OFF	The port is in the active state but there is no
			traffic on the port.
	Green LED	ON	The port is connected properly.
	(right)	OFF	The port is not connected or is incorrectly
			connected.
The D/S LED is	Yellow LED	ON	The port operates in the full duplex mode.
on	(left)	OFF	The port operates in the half duplex mode.
	Green LED	ON	The port rate is 100 Mbps.
	(right)	OFF	The port rate is 10 Mbps.

You can change the mode of the port status LEDs by pressing the Mode button. After a switch is powered on, the A/L LED is on initially. If you press the Mode button, the D/S LED will be on. After that, if you press the Mode button again within 45 seconds, the A/L LED will be on again. Otherwise, the A/L LED will automatically be on 45 seconds later.

n	The Switch 4210 26-port, 18-port, and 9-port PWR models provide an
	over-temperature protection mechanism. When the internal temperature exceeds
	65°C (149°F), they will stop providing power from all ports. When the temperature
	is below 60°C (140°F), they will continue to provide power from all ports.
