ethernet leds are amber netgear prosafe GS748T
Hi, I hope somebody help me. We have a switch netgear ProSafe GS748T, and suddenly, the leds that indicates if any port is occupied are amber, even if the port is empty, and they don't blink, all of ...
Hello caifan125,
Port LEDs turn amber/yellow when it is running a 10/100mbps speed with the LAN device connected to it.
• Solid Green - A valid 1000 Mbps link is established on the port.
• Flashing Green - Packet transmission or reception is occurring on the port at 1000 Mbps.
• Solid Yellow - A valid 10/100 Mbps link is established on the port.
• Flashing Yellow - Packet transmission or reception is occurring on the port at 10/100 Mbps.
• Off - No 10/100 Mbps link is established on the port.
• Solid Green - Full-duplex link is established on the port.
• Off - No full-duplex or half-duplex link is established on the port.
However, in your case, even if the LAN port is empty it still lights up. That does not sound right. I suggest you do factory reset on the switch, FW update if you can access the admin page. And if youg et the same results, it needs replacement.

Hello caifan125,
It should be MAC address of the switch, this MAC address will only show up right when the switch is properly connected to the network and working as it should. Even when you connect the switch to the computer directly and switch is not connected to the network, the MAC address should still show up.
I guess try installing the switch and configure the IP address first.

I will try, thanks for your help
Hi, I'm having same problem. How do you finally fix it ?
all leds in yellow (without nics connected)
Hi juantxu,
LAN ports should be off and no light lit up when there is no LAN device plugged in.
If you have any special config on the switch such as LAG, VLANs, QoS, etc., back up the config first then hard reset the switch. May be best if you update the firmware if it is not updated yet.
