No Interface Card is connected 2. No SFP+ transceiver/cable is connected to the installed Interface Card 3. An SFP+ transceiver/cable is connected to the corresponding port of the Interface Card, but it is not connected to a device  10/100/1000Mbps RJ45 Ports: Port 1-24, designed to connect to a device with the bandwidth of 10Mbps, 100Mbps or 1000Mbps. Each has a corresponding Link/Act LED.  SFP Ports: Port 21F-24F, designed to install the SFP transceiver. These four SFP transceiver slots are shared with the associated RJ45 ports. The associated two ports are referred as a "Combo" port, which means they cannot be used simultaneously, otherwise only RJ45 port works. The SFP ports support 1000M SFP module connection only.  SFP+ Ports: Port 25-26, designed to install the 10Gbps SFP+ transceiver/cable. T2700G-28TQ also provides an interface card slot on the rear panel to install the expansion 10

10/100/1000Mbps RJ45 Ports:
Port 1-24, designed to connect to a device with the bandwidth
of 10Mbps, 100Mbps or 1000Mbps. Each has a corresponding Link/Act LED.
SFP Ports:
Port 21F-24F, designed to install the SFP transceiver. These four SFP transceiver
slots are shared with the associated RJ45 ports. The associated two ports are referred as a
“Combo” port, which means they cannot be used simultaneously, otherwise only RJ45 port
works. The SFP ports support 1000M SFP module connection only.
SFP+ Ports:
Port 25-26, designed to install the 10Gbps SFP+ transceiver/cable.
