 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
