The D-Link 8-Port Desktop Switch with 4 PoE Ports enables both home and office users to easily connect and supply power to Power over Ethenet (PoE) devices such as wireless Access Points (APs), IP cameras, and IP phones while adding more Ethernet devices like computers, printers, and Network Attached Storage (NAS) onto a network. Built with home and small business users in mind, this compact PoE switch operates quietly, making it ideal for use in virtually any room or office. POWER OVER ETHERNET IEEE 802.3af The DES-1008PA features 4 10/100BASE-TX ports that support the IEEE 802.3af PoE protocol. Each of the 4 PoE ports can supply up to 15.4 Watts, a total PoE budget of 56 Watts, allowing users to attach an IEEE 802.3af compliant device to the DES-1008PA without requiring additional power. This eliminates the need of having to place networking devices within close proximity of a power outlet and minimizes cable clutter in awkward places such as ceilings or walls. For devices that are not 802.3af compliant, a PoE adapter, such as D-Link’s DWL-P50 can be used to enable the non-compliant device to receive power through the DES-1008PA. SUPERIOR PERFORMANCE No configuration is required and installation is quick and easy. Support for Auto-MDI/MDI-X on all ports eliminates the need for crossover cables for connection to another switch or hub. Auto-Negotiation on each port senses the link speed of a network device (either 10 or 100) and intelligently adjusts for compatibility and optimal performance. When an IEEE 802.3af compliant device is attached, power supplied to that device will be automatically adjusted to fit the device. The DES-1008PA also features diagnostic LEDs, which display status and activity, allowing you to quickly detect and correct problems on the network. With wire-speed filtering and store-and-forward switching, the DES-1008PA also maximizes network performance while minimizing the transmission of bad network packets
