JetNet 3705-24V 5-port Industrial Fast Ethernet Power over Ethernet Switch
Troubleshooting
Verify that you are using the right power cord/supplier/adapter (DC 24V/48V),
please don't use the power supplier/adapter with a non-compliant DC output voltage,
or it will burn the equipment.
Select the proper UTP/STP cable to construct your network. Please check that you
are using the right cable. Use unshielded twisted-pair (UTP) or shield twisted-pair
(STP) cable for RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps
connections, 100Ω Category 5 cable for 100Mbps connections, or 100Ω Category
5e/above cable for 1000Mbps. Also be sure that the length of any twisted-pair
connection does not exceed 100 meters (328 feet).
Diagnosing LED Indicators: To assist in identifying problems, the Switch can be
easily monitored through LED indicators on the front panel, which describe common
problems the user may encounter and where the user can find possible solutions.
If the power indicator does not light on when the power cord is plugged in, user may
have a problem with the power cord. Then check for loose power connections,
power losses or surges at power outlet. If you still cannot resolve the problem,
contact the local dealer for assistance.
If the Industrial switch LED indicators are normal and the connected cables are
correct but the packets still cannot transmit. Please check your system's Ethernet
devices' configuration or status.
