The Structure Of The Hub
Sep 09, 2021
The external board structure of ordinary hubs is very simple. For example, D-Link's simplest 10BASE~T EthernetHub hub is a rectangular parallelepiped, with AC power sockets and switches, an AUI interface and a BNC interface on the back, and a row of 17 RJ-45 interfaces on most of the front.
On the right side of the front, there are LED interface indicators and LED status indicators corresponding to each RJ-45 interface. High-end hubs are not much different from modern routers or switching routers from the outside. In particular, modern dual-speed adaptive Ethernet hubs generally have built-in switching modules that can communicate with each other between internal 10Mb/s and 100Mb/s network segments, so that this type of hub can be used in the network segment with the hub as the node. , To realize the communication exchange between various nodes, and sometimes people simply call this type of switching hub a switch, which makes it difficult for users who use the hub for the first time to distinguish them correctly. However, it is a relatively simple method to determine the hub based on the type of backplane interface.
