There are two modes of PoE, A and B. Mode A delivers power on the data pairs of 100BASE-TX or 10BASE-T. Mode B delivers power on the spare pairs. PoE can also be used on 1000BASE-T Ethernet, in which case there are no spare pairs and all power is delivered using the phantom tec...

The term network topology is used to denote the arrangement of the network devices in a computer network. Network topology may be used to show physical or logical arrangement of devices inside a computer network. A network topology diagram allows a network engineer to visualize how the devices ar...
However, since you need to be able to connect >two hubs/switches together you have to switch one of the ports to >"uplink" mode, which makes that port wired as a host. Thank you H. Peter for your lengthly explanation! How many switches can be cascaded? What is the time delay ...
firewalls and hubs -- with Ethernet ports that could auto detect whether the device on the opposite side of the cable was attempting to link via MDI or MDIX. In turn, the interface automatically switches between MDI and MDIX operational mode using software. This enables admins to use either ...
A PoE (Power over Ethernet) Switch is a network switch which can provide PoE (Power over Ethernet) technology. A PoE (Power over Ethernet) Switch can provide both power and data over Ethernet twisted pair cable simultaneously. A PoE (Power over Ethernet) Switch can simplify the cabling and ...
The main advantage of Full-Mesh topology is multiple paths to the destination computer. If one link is down, we have another path to reach the destination. ForLANnetworking, Full-Mesh topology is not commonly used these days. Full-Mesh topology is used for site-to-siteWANconnectivity, to inc...
