Thanks for choosing the TL-SG5428/TL-SG5412F JetStream L2 Managed Switch! 
2.1 Overview of the Switch
TL-SG5428 and TL-SG5412F are Gigabit Ethernet switching products recently developed by 
TP-LINK. TL-SG5428 possesses 24 RJ45 ports and 4 SFP slots, while TL-SG5412F 
characterizing with 12 SFP slots and 4 RJ45 ports. The SFP slot enables remote connection with 
SFP slots on other devices through SFP module and fiber. TL-SG5412F is compatible with all 
kinds of gigabit SFP modules. Here you are recommended to choose gigabit SFP module 
produced by TP-LINK, which can perfectly extended your network and enlarge the bandwidth. 
TL-SG5412F is your first choice to extend the originally large and medium-sized network. 
Designed for workgroups and departments, TL-SG5428/TL-SG5412F from TP-LINK provides 
wire-speed performance and full set of layer 2 management features. It provides a variety of 
service features and multiple powerful functions with high security.  
The EIA-standardized framework and smart configuration capacity can provide flexible solutions 
for a variable scale of networks. ACL, 802.1x, IP Source Guard and Dynamic ARP Inspection 
provide robust security strategy. QoS and IGMP snooping/filtering optimize voice and video 
application. Link aggregation (LACP) increases aggregated bandwidth, optimizing the transport of 
business critical data. SNMP, RMON, WEB/CLI/Telnet Log-in bring abundant management 
policies. TL-SG5428/TL-SG5412F switch integrates multiple functions with excellent performance, 
and is friendly to manage, which can fully meet the need of the users demanding higher networking 
performance.
