Product OutlineSwitch-S24GPWR is an Ethernet Switching Hub with management function having 24ports of 10/100/1000BASE-T.Ports 1 to 24 support IEEE802.3af PoE power supply function.1.1 Features71 Ports 1 to 24 are 10/100/1000BASE-T ports corresponding to auto negotiation.Also their speed and communication mode can be switched by configuration. Ports 1 to 24 can supply power conforming with IEEE802.3af. Supplying power upto 15.4 W per port, and up to 124 W in total is possible. All twisted pair ports support straight/cross cable auto sensing function. Simplyconnect devices with straight cables, whether it is a terminal or a network device.(This function does not work if the port communication configuration is set at Fixedor Link Aggregation. Ports 1 to 22 are set at MDI-X. (default)) Has the IEEE 802.3az (LP1)-compliant Energy Efficient Ethernet function (hereafterreferred to as EEE). This function automatically saves power when there is no datacommunication in the linkup state, allowing a reduction in the power consumptionof each port. Embedded power saving mode detects the connection status automatically andsaves power consumption to minimum. VLAN function allows free grouping of up to 256 VLANs. The IEEE802.1p compatible QoS function is supported. Has a loop detection function, which notifies when a loop occurs with thecorresponding port LED and automatically shuts down the looped port. Has a loop detection history function, which notifies when a loop occurs with thecorresponding LED and enables a network administrator to identify the looped portafter the loop is removed. Using the PoE scheduler function, power supply control for PoE can be scheduled.
