„
Verify that is using the right power cord/adapter (DC 48V), please don’t use the
power adapter with DC output voltage higher than 48V, or it will burn this
equipment down.
„ Select the proper UTP/STP cable to construct your network. Please check that is
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: the Switch can be easily monitored through panel
indicators, which describes common problems user may encounter and where
user can find possible solutions, to assist in identifying problems.
„ If the power indicator does not light on when the power cord is plugged in, user
may have a problem with 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.
