Frequently Asked Questions (FAQ)
The Power LED should be lit when the power system is working normally. If the Power
LED is not lit, please check as follows:
A1:
Make sure the AC power cord/power adapter is connected 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.
Q1. Why is the Power LED not lit?
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 working well.
A3:
The cable must be less than 100 meters long (328 feet). If Extend Mode is enabled,
it should be less than 250 meters (820 feet).
Q2. Why is the Link/Act LED not lit when a device is
connected to the corresponding port?
When the total power consumption of connected PoE devices exceeds the maximum,
the PoE port with a smaller port number has a higher priority. The system will cut o
power to the ports with larger port numbers to ensure supplying to other ports.
For example, if port 1, 2 and 4 are consuming 10 W respectively, and an additional PoE
device with 15 W is inserted to port 3, the system will cut o the power of port 4 to
compensate for the overload.
Q3. Why are PoE ports not supplying power for PoE devices?
A1:
Before upgrading a connected PoE powered device (PD), disable PoE Auto
Recovery to avoid the PD’s damage.
A2:
When a PD does not send data packets to the switch for a long period in certain
scenarios (e.g. an IPC in sleep mode), disable PoE Auto Recovery to avoid the PD
repeatedly rebooting.
Q4. What should I notice before using the PoE Auto Recovery
feature?
