Master high-end switch cascade to instantly become a master of the Network

Master the high-end switch cascade to instantly become a master of the network, previously introduced the relevant knowledge. After the publication of the stack and cascade of switches, we have received a number of emails from many readers to discuss with us about the cascade of switches. So we will introduce some related content about high-end switch cascade. High-end switch cascade: optical transceiver connection When optical cables are used for cab

Detailed explanation of wiring construction requirements

unplug the twisted pair cable, which does not affect the work of other nodes;G. Twisted Pair wires are generally not installed outside the room. When a small part is installed outside the room, casing should be installed in the outdoor part;H. Select the eight-core twisted pair wires. When you install the connectors on your own, the eight wires should be installed properly. Do not install only four wires or cut off the other four wires. Iv.
