And the access or aggregation of the campus network and the connection of the data center server farm.1.

Pre-terminated trunk cables are typically used in the connection of trunk and crossover cabling in the data center. This pre-terminated cable simplifies the installation process, saves time and labor costs compared to field termination. Now there are variety of pre-terminated trunk cables in the mar

The Huawei S5700-28P-PWR-LI-AC switch is a new generation of green, energy-efficient Gigabit Ethernet switches introduced by Huawei that can meet the needs of large broadband access and Ethernet multi-service development. This switch uses a high-performance hardware chip, with large capacity, high-d

We know that in the present market, Gigabit Ethernet switches generally have two ports: RJ45 port and SFP port, both of which can be transmitted with Gigabit Ethernet. Then what are the differences between the two ports? How should we wire them respectively? This tutorial will answer one by one.Giga

In terms of performance, industrial Ethernet switches and ordinary switches are not much different. From the network level, there are two switches, of course, there are three switches. Industrial Ethernet switch has a stress in its product design and component selection, which meets industrial field

Network monitoring system in our security occupies an absolute position. In the high-definition network video surveillance system, customers often have a feedback of the delay, Caton and other phenomena, caused for many reasons, but in most of the situation, they are caused by unreasonable switch co

A simple definition of the fourth layer exchange is that it is a function that determines transmission based not only on the MAC address (the second layer network bridge) or source/destination IP address (the third layer routing) but also on TCP / UDP (the fourth layer) application port number. The

POE (Power Over Ethernet) refers to the technology that existing Ethernet Cat.5 cabling infrastructure without any changes can transmit data signals for some IP-based terminals (such as IP telephones, wireless LAN access point AP, network camera Etc.) while transmitting data signals, but also provid

Cisco network equipment has a variety of models, which often confuses people and makes it difficult to record, so it’s necessary to conclude the meanings that various product models stand for.1. The meaning of the letters in the Cisco product models1. Product models that start with CISCO are routers
