Troubleshooting

This section is intended to help user solve the most common problems on the 8 10/100/1000Base-T with 1 1000Base-X SFP/RJ45 Combo port Web Managed Switch with.

Incorrect connections

The switch port can auto detect straight or crossover cable when link switch with other Ethernet device. For the RJ-45 connector should use correct UTP or STP cable, 10/100Mbps port use 2 pairs twisted cable and Gigabit 1000T port use 4 pairs twisted cable. If the RJ-45 connector is not correct pin on right position then the link will fail. For fiber connection, please notice that fiber cable mode and fiber module should be match.
