5. Troubleshooting
This chapter contains information to help you solve issues. If the Industrial Gigabit
PoE+ Switch is not functioning properly, make sure the Industrial Gigabit PoE+
Switch is set up according to instructions in this manual.
The Link LED does not light up
Solution:
Check the cable connection and also try to swap one new cable.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The Industrial Gigabit PoE+
Switch runs in auto-negotiation mode and if the partner is set to half duplex, then
the performance will be poor.
1000BASE-T port link LED lights up, but the traffic is irregular
Solution:
Check whether 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 Industrial Gigabit PoE+ Switch doesn’t connect to the network
Solution:
Check each port LED on the Industrial Gigabit PoE+ Switch. Try another port on
the Industrial Gigabit 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 after my PoE PD device is connected to IGS-504HPT/IGS-624HPT, it
cannot power on?
Solution:
1. Please check the cable type of the connection from IGS-504HPT/IGS-624HPT
(port 1 to port 4) 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, all will affect the power supply.
2. Please check and assure the device is fully complied with IEEE 802.3af/IEEE
802.3at standard.
Can I install MGB-SX or other non wide temperature SFP module into SFP
slot of Industrial Gigabit PoE+ Switch?
Solution:
Yes, you can. However, since the MGB-SX and other non wide temperature SFP
modules cannot operate under -40 degrees C, it must be brought to attention.
Please pay attention to this point.
