1	PWR indicator	2	Twenty-four GE PoE+ electrical ports
3	Electrical port indicator	4	Two GE optical ports
5	Optical port indicator	6	Port mode switch button NOTE: Standard Mode: All ports are in the same VLAN, and the flow control function is enabled. Port Isolation: All downlink ports are isolated from each other and cannot communicate with each other. Downlink ports can communicate only with uplink ports. (The last two downlink electrical ports are not isolated.) Uplink ports are not isolated or aggregated. Uplink Aggregation: Two uplink optical ports are aggregated into a trunk interface. Eth-Trunk supports load balancing only based on source physical ports. Flow Control Disabling: All ports are in the same VLAN and flow control is disabled.
7	Port indicator status switch button NOTE: Port status: The port indicator indicates the data transmission status of the port. PoE status: The port indicator indicates the PoE status of the port.	8	Ground screw
9	AC socket NOTE: Use the power cable delivered with the device.	–	–

Description

Available Components

GE PoE+ electrical port

RJ45

A GE PoE+ electrical port sends and receives service data at 10/100/1000 Mbit/s.

The port supports the PoE function.

Ethernet cable

GE optical port

SFP

A GE optical port can send and receive data at 100/1000 Mbit/s.

FE SFP/eSFP optical modules (only optical modules with transmission distances less than or equal to 15 km are supported)
GE eSFP optical modules (only optical modules with transmission distances less than or equal to 10 km are supported)

Indicators and Buttons

Table 4-23 Description of indicators on the device

Indicator	Color	Status	Description
PWR indicator	–	Off	The device is powered off.
PWR indicator	Green	Steady on	The power supply is normal.
Port indicator (Port status)	–	Off	The port is not connected or has been shut down.
	Green	Steady on	A link has been established on the port. NOTE: During device startup, all port indicators are steady green for about 2 seconds and then off, indicating that service initialization is complete.
	Green	Blinking	The port is sending or receiving data.
Port indicator (PoE status)	–	Off	The port is not supplying PoE power.
	Green	Steady on	The port is supplying power to the connected PD.
	Green	Blinking	The PoE power of the device is insufficient, and the port cannot provide power to the PD.

Power Supply System

The device uses the power adapter delivered with the device to supply power to the device and the connected PD. The power adapter can provide 124 W PoE power, which ensures full PoE power on 8 ports in compliance with 802.3af or on 4 ports in compliance with 802.3at.
