Smart PoE+ Switch
T1500-28PCT (TL-SL2428P)
Overview
The T1500-28PCT provides 24 10/100Mbps ports that supports 802.3at/af-compliant PoE,
with a total PoE power supply up to 180W, powerful and exible enough for users to
deploy wireless access points or IP-based network surveillance cameras. The switch also
comes equipped with 4 10/100/1000Mbps RJ45 ports and 2 combo SFP slots, expanding
your network exibly. In addition, it provides high performance, enterprise-level QoS,
useful security strategies and rich layer 2 management features.
TP-LINK Smart PoE Switch T1500-28PCT is a cost-eective product solution for the small
and medium business. T1500-28PCT has useful security features. The Storm Control
feature protects against Broadcast, Multicast and Unknown unicast Storm. Quality of
Service (QoS, L2 to L4) provides enhanced trac management capabilities to move your
data smoother and faster. Anymore, the easy-to-use web management interfaces, along
with SNMP and RMON, mean faster setup and conguration with less downtime. For
workgroup and departments requiring cost-sensitive layer 2 switch, TP-LINK Smart PoE
Switch T1500-28PCT provides you the ideal access-edge solution.

T1500-28PCT (TL-SL2428P)
IEEE 802.3at/af-compliant Power over Ethernet
The T1500-28PCT supports 24 ports of IEEE 802.3at/af-compliant PoE and has a total
power supply of 180W to power any 802.3at or 802.3af compliant power device. It’s
an ecient and cost-eective choice to work with wireless access points, surveillance
cameras, IP phones and other PoE supported devices, while getting rid of cables or
power lines running around. Compact and exible, the T1500-28PCT is ideal to
exibly use PoE to deploy wireless access points or IP-based network surveillance
cameras for projects or small business networks.
Advanced QoS Features
To integrate voice, data and video service on one network, the switch applies rich
QoS policies. Administrator can designate the priority of the trac based on a variety
of means including Port Priority, 802.1P Priority and DSCP Priority, to ensure that
voice and video are always clear, smooth and jitter free. In conjunction with the Voice
VLAN the switch supports, the voice applications will operate with much smoother
performance.
Abundant Layer 2 features
For more application of layer 2 switches, T1500-28PCT supports a complete lineup of
layer 2 features, including 802.1Q tag VLAN, Port Isolation, Port Mirroring, STP/RSTP/MSTP, Link Aggregation Group and 802.3x Flow Control function. Any more, the
switches provide advanced features for network maintenance such as Loop Back
Detection, Cable Diagnostics and IGMP Snooping. IGMP snooping ensures the switch
intelligently forward the multicast stream only to the appropriate subscribers while
IGMP throttling<ering restrict each subscriber on a port level to prevent unauthorized multicast access.

Enterprise Level Management Features
T1500-28PCT is easy to use and manage. It supports various user-friendly standard
management features, such as intuitive web-based Graphical User Interface (GUI) or
SNMP (v1/2/3) and RMON support enables the switch to be polled for valuable status
information and send traps on abnormal events.
