Panel Explanation
Power LED
| On: Power on
Off: Power off
Flashing: Loop occurs in the network topology
---|---
Link/Act LED
| On: Running at 10/100/1000 Mbps
Off: No device is linked to the corresponding port
Quick flashing: Transmitting/receiving data
Slow flashing: Loop is detected on the corresponding port
---|---
Switch
| On: The switch will monitor and address loop-related issues within the
network
structure to prevent disruptions caused by redundant pathing
Off: (default) The switch will not try to monitor or address loop-related
issues

Frequently Asked Questions (FAQ)
Q1. The Power LED is not lit.
The Power LED should be lit when the power system is working normally. If the Power LED is not lit, check as follows: A1: Make sure the power adapter is connected to the switch with power source properly. A2: Make sure the voltage of the power supply meets the requirements of the input voltage of the switch. A3: Make sure the power source is ON.
Q2. The Link/Act LED is not lit when a device is connected to the corresponding port.
It is recommended that you check the following items: A1: Make sure that the cable connectors are firmly plugged into the switch and the device. A2: Make sure the connected device is turned on and works normally. A3: The cable must be less than 100 meters long (328 feet).
Q3. Why does the switch fail to detect and block a loop from occurring in the network topology when Loop Prevention is enabled?
A: When this switch is connected to other non-terminal devices, such as switches of other brands, and the device is incapable of correctly processing or forwarding loop detection packets, the Loop Prevention function will be limited. It is recommended to connect the terminal devices directly to this switch or connect non-terminal devices with complete forwarding capability to this switch.
