DGS-1250 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide LED PoE DGS-1250-28XMP DGS-1250-52XMP Description RJ45 Ports: This LED will light solid green when there is a connection (or link) to a 1000 Mbps Ethernet device or solid amber when there is a connection (or link) to a 10/100 Mbps Ethernet device on any of the RJ45 ports. The LED will blink green when a 1000 Mbps port is active or blink amber when a 10/100 Mbps port is active. The LED will be off when there is no link or activity. SFP/SFP+ Ports: This LED will light solid green when there is a connection (or link) to a 10 Gbps Ethernet device or solid amber when there is a connection (or link) to a 1 Gbps Ethernet device at any at any of the SFP/SFP+ ports. The LED will blink green when a 10 Gbps port is active or blink amber when a 1 Gbps port is active. The LED will be off when there is no link or activity. This LED will light solid green when the corresponding ports are feeding power to the PoE devices plugged in. This LED will light solid amber when the port is in an error condition state. This LED will be off when the ports are not supplying power to the devices plugged into the ports.

LED
Description
RJ45 Ports:
This LED will light solid green when there is a connection (or link) to
a 1000 Mbps Ethernet device or solid amber when there is a connection (or link)
to a 10/100 Mbps Ethernet device on any of the RJ45 ports. The LED will blink
green when a 1000 Mbps port is active or blink amber when a 10/100 Mbps port is
active. The LED will be off when there is no link or activity.
SFP/SFP+ Ports:
This LED will light solid green when there is a connection (or
link) to a 10 Gbps Ethernet device or solid amber when there is a connection (or
link) to a 1 Gbps Ethernet device at any at any of the SFP/SFP+ ports. The LED
will blink green when a 10 Gbps port is active or blink amber when a 1 Gbps port
is active. The LED will be off when there is no link or activity.
PoE
DGS-1250-28XMP
