NETGEAR 10/100/1000 Mbps Gigabit Ethernet GS108 - Manual (Page 7)

Troubleshooting
The Power light is not lit
The switch has no power.
• Make sure the power cord is properly connected to the switch.
• Make sure the power adapter is properly connected to a functioning power outlet. If it’s 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.
• Make sure you are using the NETGEAR power adapter supplied with your switch.
The Port number light is not lit for a connected device or
stays on continuously
There’s a hardware connection problem.
• Make sure the cable connectors are securely plugged in at the switch and the device.
• 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).
