IE4320-20P			Enables or disables link aggregation on ports 17 and 18	Enables or disables RRPP on ports 19 and 20

When DIP switch 1 is on, flow control is enabled on all ports. When DIP switch 1 is off, the status of the flow control feature depends on the configuration. For more information about flow control, see Ethernet interface configuration in the configuration guides for the switch.

When DIP switch 2 is on, broadcast suppression is enabled on all ports. When DIP switch 2 is off, the status of the broadcast suppression feature depends on the configuration. For more information about broadcast suppression, see Ethernet interface configuration in the configuration guides for the switch.

When DIP switch 3 is on, the system creates Layer 2 aggregation group 1 and adds the two uplink Ethernet ports to the group. When DIP switch 3 is off, the status of the link aggregation feature depends on the configuration. For more information about Layer 2 link aggregation, see Ethernet link aggregation configuration in the configuration guides for the switch.

When DIP switch 4 is on, RRPP is enabled. When DIP switch 4 is off, the status of the RRPP feature depends on the configuration. For more information, see RRPP configuration in the configuration guides for the switch.

LEDs

System status LED

Only the IE4320S rack mounting industrial switches each provide a system status LED on the front panel to indicate the operating status of the switch.

Table4-12 System status LED description

LED mark	Status	Description
SYS	Steady yellow	Boot ROM booting stage.
	Steady green	Linux kernel booting stage, or the switch has started up correctly.
	Flashing green (1 Hz)	Software image loading and decompressing stage, or software booting stage.
	Steady red	The switch has failed power-on self test (POST) or the switch is faulty.
	Off	The switch is powered off or has not started up correctly.

Removable power supply status LED

Only the IE4320S rack mounting industrial switches each provide two power supply slots at the rear. For each power supply, the switch provides a power supply status LED on the front panel.

	Off	No power supply is installed in the power supply slot.

Fixed power supply status LED

All IE4320 industrial switches except the IE4320S-26S and IE4320S-50S switches use fixed power supply status LEDs to indicate the power input status. Table4-14 provides the description of the fixed power supply status LEDs on the switch.

The IE4320-12P-PWR-M switch provides a built-in power adapter. The compatible power cord contains two DC input circuits for redundancy.

Table4-15 Description for the power supply status LED on the IE4320-12P-PWR-M switch

LED mark	Status	Description
PWR1/PWR2	PWR1: Steady green PWR2: Steady green	Normal DC power input
	PWR1: Off	Active DC power input failure has occurred or no power input.
	PWR2: Off	Standby DC power input failure has occurred or no power input.

PoE status LED

Only the IE4320-12P-PWR-M and IE4320-12P-PWR-M-NAT switches provide a PoE status LED to indicate the PoE power supply status.

Table4-16 PoE status LED description

LED mark	Status	Description
PoE+	Steady yellow	PoE is enabled on the Ethernet port.
PoE+	Off	PoE is disabled on the Ethernet port.

Alarm LED

All IE4320 industrial switches except the IE4320S-26S and IE4320S-50S switches each provide an alarm input connection and can detect changes of the digital input voltage. When the digital input voltage exceeds the acceptable range, the system uses the alarm LED to indicate the exception.

Table4-17 Alarm LED description

LED mark	Status	Description
Alarm	Steady red	A digital input exception has been detected.
Alarm	Off	No exception has been detected.

Diag LED

All IE4320 industrial switches except the IE4320S-26S and IE4320S-50S switches each provide a Diag LED on the front panel to indicate the system operating status.

Table4-18 Diag LED description

LED mark	Status	Description
Diag	Steady red	The switch has failed the POST, or an alarm condition such as MAC chip overtemperature has occurred.
Diag	Off	The switch has passed the POST and is operating correctly.
