The DGS-1008P PoE Gigabit Desktop switch provides a cost-effective way for office users to easily connect and supply power to Power over Ethernet (PoE) devices such as wireless access points (APs), IP cameras, and IP phones. It also provides the opportunity to add additional Ethernet devices like computers, printers, and Network Attached Storage (NAS) onto a network. This compact PoE switch is equipped with Gigabit ports for faster speeds and operates quietly, making it ideal for use in virtually any room or office. In addition, D-Link's Green Ethernet technology saves power when the switch is active and inactive.Cable diagnostics functionEvery time the DGS-1008P is powered up, it runs a micro diagnostics routine to check the integrity of the connected Ethernet cables. If a failure is detected, the switch will flag it by means of its front panel LEDs, making it easy for the user to troubleshoot wiring problems.
