The switch from Mercusys is useful for creating or expanding a wired network. If the ethernet ports of the router are not enough for the wired connections of all your devices, a switch will help you. It is unmanaged, meaning it does not offer the ability to configure its settings, which makes it more economical. It is mainly recommended for simple users who simply want to expand their small home network and for small businesses with no special requirements. It has 5 ethernet ports with a maximum speed of 1Gbps. It features Power over Ethernet (PoE) technology, which allows it to simultaneously transmit power and data over an Ethernet cable. Before choosing a switch with PoE, you need to know how much power your devices consume. This specific one has PoE (802.3af) and PoE+ (802.3at), suitable for high power requirements of devices such as IP video phones, HD PTZ IP cameras, 802.11ac (WiFi 5) AP, small speakers, or sound systems.
