5. Troubleshooting

This chapter contains information to help you solve issues. If the 802.3at PoE+ 
Switch is not functioning properly, make sure the 802.3at PoE+ Switch was set up 
according to instructions in this manual.

The Link LED is not lit.
Solution:

Check the cable connection and also try to swap one new cable.

1000BASE-T port link LED is lit, but the traffic is irregular.
Solution:

Make sure the attached device is not set to 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 Switch doesn’t connect to the network
Solution:

Check the LNK/ACT LED on the 802.3at PoE+ Switch. Try another port on the 
802.3at PoE+ Switch. Make sure the cable is installed properly. Make sure the 
cable is the right type. Turn off the power. After a while, turn on the power again.

Why the GSD-1002VHP/GSW-1820VHP/GSW-2620VHP, connected to PoE 
device, cannot be powered on
Solution:

Please check the cable type of the connection from GSD-1002VHP/GSW-1820VHP/
GSW-2620VHP to the other end. The cable should be an 8-wire UTP, Category 5 or 
above and EIA568 cable within 100 meters. A cable with only 4-wire, short loop or 
over 100 meters will affect the power supply.

Please make sure the device is fully complied with IEEE 802.3af/IEEE 802.3at 
standard.

What is the power output of each PoE port?
Solution:

1. Each PoE port supports 

53V-54 DC, 600m

A and a 

maximum of 30 watts

 of 

power output. Detect and inject by the standard of IEEE 802.3at.

2. Each PoE port supports 

53V-54 DC, 300mA

 and a 

maximum of 15.4 watts

 

of power output. Detect and inject by the standard of IEEE 802.3af.
