Cudy's CD-FS1018PS is a 16 Port Fast Ethernet switch with 16x 802.3af/at PoE ports and 2x Gigabit, 1x SFP Combo Uplink ports. The switch offers a 190W PoE budget, up to 30W per PoE port with a VLAN and Extender toggle switch. VLAN mode enables port isolation on ports 1-16 while Extender mode increases the transmission distance on ports 1-16 to 250m at 10Mbps. The watchdog function continuously monitors PoE connections. If an error is detected on the device, the switch immediately restarts the port.
