No.	Indicator	Name	Color	Status	Description
1	PWR	Power module indicator	-	Off	The switch is powered off.
			Green	Steady on	The power supply is normal.
			Yellow	Steady on	The power supply is abnormal.
2	SYS	System status indicator	-	Off	The system is not running.
			Green	Fast blinking	The system is starting.
			Green	Steady on	During the system startup preparation phase, the SYS indicator is steady green, which lasts for a maximum of 30 seconds.
			Green	Slow blinking	The system is running normally.
			Red	Steady on	The system does not work normally after registration, or a fan alarm or a temperature alarm has been generated.
3	MST	Stack indicator	-	Off	If you are not changing the indicator mode (default): The switch is a standby or slave switch in a stack or the stacking function is not enabled on the switch. If you are changing the indicator mode: The stack mode is not selected.
			Green	Steady on	The stack mode is selected. The switch is a standby or slave switch in a stack, and the service port indicators show the stack ID of the switch.
			Green	Blinking	If you are not changing the indicator mode (default): The switch is the master switch in a stack or a standalone switch with the stacking function enabled. If you are changing the indicator mode: The stack mode is selected. The switch is the master switch in a stack or a standalone switch, and the service port indicators show the stack ID of the master switch. After 45 seconds, the service port indicators automatically restore to the status mode.
4	PoE	PoE indicator	-	Off	The PoE mode is not selected.
			Green	Steady on	The PoE mode is selected, and service port indicators show the PoE status of each port.
5	MODE	Mode switch button	-	-	When you press this button once, the service port indicators change to the stack mode and show the stack ID of the local switch. When you press this button a second time, the service port indicators change to the PoE mode and show the PoE status of each service port. When you press this button a third time, the service port indicators restore to the default mode and show the connection status and link activity of each service port. If you do not press the MODE button within 45 seconds, the service port indicators restore to the default mode. In this case, the PoE indicator is off. NOTE: In V600R023C00 and later versions, hold down the mode switch button for 6s and release it to start the web initial login mode. Either of the following situations will occur: If the switch has no configuration file, the system attempts to enter the web initial login mode. If the system enters the web initial login mode successfully, the MST mode indicator turns green and stays on for a maximum of 45 seconds. If the login fails, check whether the device uses factory default settings.
6	-	Service port indicator (one indicator for each port)	Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top.		Meanings of service port indicators vary in different modes. For details, see Table 4-238. NOTE: If a power failure occurs on a device's PCB board, indicators of the last four GE, 10GE, or 25GE optical ports on the device's front panel blink green cyclically at an interval of 1 second, with each indicator illuminating for 0.25 seconds.
7	ID	ID indicator	-	Off	The ID indicator is not used (default state).
			Blue	Steady on	The indicator identifies the switch to maintain. The ID indicator can be turned on or off remotely to help field engineers find the switch to maintain.

	Green	Steady on	The switch is not the master switch in a stack. If the indicator of a port is steady on, the number of this port is the stack ID of the switch.
	Green	Blinking	The switch is the master switch in a stack. If the indicator of a port is blinking, the number of this port is the stack ID of the switch.
PoE mode	-	Off	The port is not providing power to a powered device (PD).
	Green	Steady on	The port is providing power to a PD.
	Green	Blinking	The power of the PD connected to the port exceeds the power capacity of the port or the power threshold configured on the port. Alternatively, the PD does not comply with IEEE standards.
Speed mode NOTE: In V600R023C00 and later versions, the service port indicators can be set to the speed mode through the set device led mode Speed diagnostic command. The default mode is automatically restored after 45s.	-	Off	The port is not connected or has been shut down.
	Green	Steady on	10/100/1000BASE-T port: The port is operating at 10 Mbit/s or 100 Mbit/s. 1GE/10GE SFP+ port: The port is operating at 1 Gbit/s.
	Green	Blinking	10/100/1000BASE-T port: The port is operating at 1000 Mbit/s. 1GE/10GE SFP+ port: The port is operating at 10 Gbit/s. 1000BASE-X port: The port is operating at 1000 Mbit/s.

Power Supply System

The switch has a built-in AC power module and does not support pluggable power modules. The built-in power module can provide 125 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.

Heat Dissipation System

The switch has a built-in fan for forced air cooling. Air flows in from the left side and front panel, and exhausts from the right side.

When working properly at a normal temperature, the device meets the desktop-class noise requirements. However, the fan speed may be high and the noise may be loud during device startup.

This figure only shows the airflow direction and does not depict the actual device.
