4.1  Ethernet Ports 

The Switch has 24 10/100Mbps and 4 10/100/1000Mbps auto-negotiating, auto-crossover 

Ethernet ports, which can be directly connected to the network devices by RJ45 cable as the 

following figure shown.   

 

Figure 4-1 Connecting the RJ45 Port 

4.2  SFP Ports 

The Switch features two SFP (Small Form-Factor Pluggable) transceiver slots that are shared with 

two associated 1000Base-T RJ45 ports. If an SFP transceiver (purchased separately) is installed 

in a slot and has a valid link on the port, the associated RJ45 port will be disabled and cannot be 

used. 

 Tips: 

TL-SL5428E supports 100/1000Base-FX SFP module at full-duplex mode.
