    Appendix B Troubleshooting • Verify that is using the right power cord/adapter (DC 24-48V), please don't use the power adapter with DC output higher than 48V, or it may damage this device. • Select the proper UTP/STP cable to construct the user network. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections that depend on the connector type the switch equipped: 100O Category 3, 4 or 5 cable for 10Mbps connections, 100O Category 5 cable for 100Mbps connections, or...
