Q1. The Power LED is not lit.
Q2. The Link/Act LED is not lit when a device is connected
to the corresponding port.
Frequently Asked Questions (FAQ)
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.
It is recommended that you check the following items:
A1:
Make sure that the cable connectors are rmly 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.
