5. Troubleshooting
This chapter contains information to help you solve issues. If the Industrial Gigabit Ethernet Switch is not functioning
properly, make sure the Industrial Gigabit Ethernet Switch was set up according to instructions in this manual.
The per port LED is not lit
Solution:
Check the cable connection of the Industrial Gigabit Ethernet Switch.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The Industrial Gigabit Ethernet Switch is run at Auto-negotiation
mode and if the partner is set to half duplex, then the performance will be poor.
Per port 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 Industrial Gigabit Ethernet Switch doesn’t connect to the network
Solution:
Check per port LED on the Industrial Gigabit Ethernet Switch. Try another port on the Industrial Gigabit Ethernet
Switch. Make sure the cable is installed properly and the right type. Turn off the power. After a while, turn on the power
again.
Can I install S30-SX or other non- wide temperature SFP module into SFP slot of Industrial Gigabit
Ethernet Switch?
Solution:
Yes, you can. However, the S30-SX and the other non- wide temperature SFP module cannot operate under -40 to 75
degrees C.
