4. Troubleshooting
This chapter contains information to help you solve issues. If the PoE Ethernet
Switch is not functioning properly, make sure the PoE Ethernet Switch is set up according to instructions in this manual.
The Link / Act LED is not lit
Solution:
Check the cable connection and remove duplex mode of the PoE Ethernet Switch.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The PoE Ethernet Switch is run at auto-negotiation mode and if the partner is set to half duplex, then the performance will be poor.
1000Base-T port link LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch to change duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.
Why the PoE Ethernet Switch doesn’t connect to the network
Solution:
Check the LNK/ACT LED on the PoE Ethernet Switch. Try another port on the PoE
Ethernet Switch. Make sure the cable is installed properly and make sure the cable is the right type. Turn off the power. After a while, turn on power again.
Why I connect my PoE device to PoE Ethernet Switch and it cannot power on
Solution:
1. Please check the cable type of the connection from the PoE Ethernet Switch
(port 1 to port 8) to the other end. The cable should be an 8-wire UTP, Category
5 or above, EIA568 cable within 100 meters. A cable with only 4-wire, short loop or over 100 meters will affect the power supply.
2. Please check and assure the device is fully complied with IEEE 802.3af / 802.3at standard.
What is the power output of each PoE port?
Solution:
Each PoE port supports 51V DC, 350mA, max 15.4 watts power output. Detect and inject by the standard of IEEE 802.3af.
Each PoE port supports 51V DC, 600mA, max 30 watts power output. Detect and inject by the standard of IEEE 802.3at.
