This misconception is surprisinglyĬommon, however it is important to remember that power ratings quotedīy manufacturers are upper limits and are not fixed. Not at all, the same cabling - Cat 5e,Ĭat 6, etc - and "RJ45"-style connectors are used for both regular and All the user has to do is wire up the networkĪs normal, and the equipment will take care of power delivery. May have required careful design, but IEEE 802.3af POE is designed toĮnsure reliable operation in any configuration that would be possible Gained universal adoption as POE's popularity has spread, meaning thatĬompatibility between all modern POE equipment is assured. If your port is faulty, you won’t have a good connection or any connection at all. Of POE, many home-brewed and proprietary schemes were employed to get This is the most basic test of your ethernet port. POE is a recently-developed technology, and many people are put offĪdopting it by the raft of conflicting or out-of-date information that The article which helped me understand why there wont be any damage These days a feature knows as auto MDI-X is used to automatically connect the two devices. The information loops and amplifies itself using the additional path instead of stopping when it reaches its destination. When networking was nascent you would have physically damaged the ports of you had not used the right cable but now with technology being "idiot proof" the network adapter automatically calibrates itself to work accordingly to prevent any damage or malfunction A network loop occurs when a network has more than one active path carrying information from the same source to the same destination. You must also know what is a patch cable and a crossover cable, patch cables are used when you want to connect to internet or a network (routers to PC) crossover cables are used to transfer information between 2 devices (computer to computer) you may have realised connecting the cable you didn't get any internet that's because you used it as a crossover cable. Here is a link I found with a quick search describing the issue its old but informative If you want details just google "what happens when two computers are connected via ethernet port " Since I don't want to setup two machines and run software on both the test connection my first thought was to create a loopback cable. The loop back she mentioned means the network traffic just bounces around and amplifies between those two ports it can physically damage the ports and/or the network adapter, this was a problem many years ago but now I must say this, most consumer network adapter are "idiot proof" Test communication of interface using Cat5E loopback Ask Question Asked 11 months ago Modified 11 months ago Viewed 214 times 1 So I need to create a simple process to test a large amount of gigabit network ports.
