Chapter 2 Introduction
Thanks for choosing the T1600-28TS/T1600G-52TS/T1600G-28PS/T1600G-52PS JetStream
Gigabit Smart Switch!
2.1 Overview of the Switch
Designed for workgroups and departments, JetStream Gigabit Smart Switch from TP-LINK
provides wire-speed performance and full set of L2 and L2+ 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. QoS and IGMP/ MLD snooping/filtering optimize voice and video
application. Link aggregation (LACP) increase aggregated bandwidth, optimizing the transport of
business critical data. SNMP/ S NM Pv6 , RMON, WEB/CLI/Telnet Log-in bring abundant
management policies.
TP-LINK JetStream Gigabit Smart 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.
T1600G-28PS/T1600G-52PS is also a Power Sourcing Equipment (PSE*). All the Ethernet RJ45
ports on the switch support Power over Ethernet (PoE*) function, which can automatically detect
and supply power with those powered devices (PDs*) complying with IEEE 802.3af and IEEE
802.3at.
*PSE: a device (switch or hub for instance) that provides power through an Ethernet cable.
*PoE: This technology describes a system to transmit electrical power, along with data, to remote
devices over standard twisted-pair cable in an Ethernet.
*PD: a device powered by a PSE and thus consumes energy. Examples include powering network
cameras, wireless LAN access points, IP telephones, network hubs, embedded computers etc.
