Verify the following: • The Power LED is lit. • The corresponding port number for each connected and powered device should light when linked (connected), and flash when activity occurs. If any light doesn't operate as indicated, see the Troubleshooting section. DC Power Jack: Power is supplied through an external DC power adapter. Check the technical specification section for information about the DC power input voltage. Be sure to connect the 48V/1.25A power adapter DC plug to the DC jack of the GS108P before plugging the power cord to AC power outlet. Grounding Connection: A grounding strap location is provided to enable you to ground the case to Earth. PoE Examples Example 1: Three PDs are connected to GS108P (Port 1 ~ Port 3) consuming 45W, leaving 5W of power available. The PoE MAX LED will light up, as there is less than 7W of power available. The GS108P will not provide power to any newly connected PD. The 5W of power is reserved for power surges by the original PD devices. When a PD is inserted to Port 4, this Port 4 will not supply power and its PoE LED will blink slowly. Example 2: Insert four PDs to Port 2, 3, 4 and 1 in order. Each PD draws 12 W. A total power draw is 48W. Since the remaining power is less than 7W, the PoE MAX LED will light up. If the PD on Port 4 surges to 15W, thereby exceeding the power budget (50W), Port 1 will stop providing power since it has the lowest priority of the 4 ports providing power. The power from Port 1 will be allocated to provide power Port 4. The PoE LED for Port 1 will blink. Example 3: Insert three PDs to Port 1, 2 and 3. Each PD draws 12 W. A total power draw is 36W. When an additional PD is inserted to Port 4 that needs 15W, powering that PD would exceed the maximum power available. Priority will be given to the PD's on ports 1, 2 and 3, since they were already plugged in, so the new PD will not receive power. The PoE LED for port 4 will blink, indicating that not enough power was available for the new PoE device.

Make sure that: • The power cord is properly connected to the switch. • The power adapter is properly connected to a functioning power outlet. If it is in a power strip, make sure the power strip is turned on. If the socket is controlled by a light switch, make sure the switch is in the on position. • You are using the NETGEAR power adapter supplied with your switch. Port number light is There is a hardware connection problem. not lit for a connected • Make sure the cable connectors are securely plugged in at the device, or stays on switch and the device. continuously • Make sure the connected device is turned on. • If the Ethernet cable is connected to a NIC or other Ethernet adapter, make sure the card or adapter is installed correctly and is working. • Make sure the cable is less than 328 feet (100 meters).
