Hello Skooter Blog readers. Today I talk about a Switch Fast Ethernet 10/100Mbps com 8 ports Auto MDI / MDIX (8-Port 10/100M Fast Ethernet Desktop Switch (Auto MDI/MDIX)) acquired on DealExtreme, whose I buy already reported in another article. Switches, or switches in good Portuguese, devices are used in computer networks to forward frames (link layer packets) between devices. Switches na atuam link layer (second layer reference model ISO / OSI), forwarding frames according to the destination address (the Ethernet MAC endereço redes).
Switches are more “Smart” do that hubs because they learn for themselves which port should forward the frames destined to each MAC address. Hubs only replicate the content you receive a door in all other ports. Switches do so only for broadcast frames (broadcast) or when you know which is the port where the recipient can be framed. Whenever it receives a frame switch checks the sender's MAC address and notes, in an internal table, this MAC address and port where the picture came. From Dai, frames destined to this MAC address will be forwarded only to the port where it is.
Exemplifying: The computer is on port 1 and computer B is on port 2. When A sends a message to B, the switch will note that the first is at the door 1 on your table. Then look for the same table B. How can not find it, He must make a broadcast of the frame received, in other words, send it to all ports in the hope that some of them are in B. When B receives the frame and sends a response to the, the switch upon receiving the painting will note also that B is at the door 2, and seeing that the recipient is the, consult your table and know that A is at the door 1, so that the frame is only sent to the port 1.
The Switch Fast Ethernet 10/100Mbps com 8 ports Auto MDI / MDIX uses the standard Fast Ethernet, supporting devices operating at 10Mbps or 100Mbps. Devices that support Gigabit Ethernet can also be connected, obviously, but work with bandwidth “only” 100Mbps. The Switch Auto MDI/MDIX, This implies that can be used both as direct cabling cables crossover, because he can identify them and use them the right way, causing a reversal in connectors, se for o caso. Are 8 ports to connect up to 8 devices.
The manufacturer of the Switch Fast Ethernet 10/100Mbps com 8 ports Auto MDI / MDIX is the U-Link. The box is all in Chinese. I managed to identify a URL, but it is not working. The model is apparently CK-00127A. The Switch has an LED that indicates when it is switched on/off and other 8 LEDs that indicate the status of each port. Access LED means you have um device connected, and flashing LED means that the device is sending / data recebendo.
At the rear there are 8 RJ45 plug entries and an entry for a source of 9V. The source that comes with the product is a 5V supply and 2A. The discrepancy between the voltage noted on switch and annotated at the source apparently causes no problem in operation. At the bottom of the Switch Fast Ethernet 10/100Mbps com 8 ports Auto MDI / MDIX There are rubber feet to set it on furniture, and also holes to hang it on the wall using two screws, so that we can install it the way you want. The source uses two parallel plans plugs, the U.S. standard, therefore not serve in the new Brazilian standard, so be sure to buy a Power Plug Adapter for Redondo Plano (Flat to Round Power Plug Converter) If you do not have to accept the American standard socket for connecting the Switch.
I am using Switch Fast Ethernet 10/100Mbps com 8 ports Auto MDI / MDIX in conjunction with a Pair EP-Rede Adapters Powerline 200Mbps HomePlug PLC5506 to bring the network to the TV room. The cable of the EP-Rede adapter HomePlug PLC5506 connects to one of the doors of the Switch Fast Ethernet 10/100Mbps. In other three ports are connected to TV, o Playstation 3 e o WD TV Live, so that all connected ficam in the network at the same time, via Switch. I have not done any performance testing, or any other more sophisticated test. I can only say that the Switch Fast Ethernet 10/100Mbps com 8 ports Auto MDI / MDIX works perfectly to suit my needs.
Besides version 8 doors, There is also a version 5 doors for those who want to save a bit more. I thought it would not be worth, after all, the price difference is only $2,10 USD (U.S. dollars two). I'm currently using only 4 doors, should I just use a fifth to connect a Blu-ray player. With version 8 doors I still will remain 3 ports for future devices. The trend is that more and more devices have option for a network, then it is always good to have some slack.
