Chapter 2 Introduction
Thanks for choosing the TL-SL5428E 24-Port 10/100Mbps + 4-Port Gigabit L2 Managed Switch!
2.1 Overview of the Switch
Designed for workgroups and departments, TL-SL5428E 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-SL5428E 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.
2.2 Main Features

business critical data.
+ IEEE 802.1s Multiple Spanning Tree provides high link availability in multiple VLAN
environments.
+ Multicast snooping automatically prevents flooding of IP multicast traffic.
+ Root Guard protects root bridge from malicious attack or configuration mistakes
•Layer 2 Switching
+ GVRP (GARP VLAN Registration Protocol) allows automatic learning and dynamic
assignment of VLANs.
+ Supports 255 active VLAN groups and 4K VLAN IDs.
•Quality of Service
+ Supports L2/L3 granular CoS with 4 priority queues per port.
+ Rate limiting confines the traffic flow accurately according to the preset value.
•Security
+ Supports multiple industry standard user authentication methods such as 802.1x, RADIUS.
+ IP Source Guard prevents IP spoofing attacks.
+ Dynamic ARP Inspection blocks ARP packets from unauthorized hosts, preventing
man-in-the-middle attacks.
+ L2/L3/L4 Access Control Lists restrict untrusted access to the protected resource.
+ Provides SSHv1/v2, SSL 2.0/3.0 and TLS v1 for access encryption.
•Manageability
+ IP Clustering provides high scalability and easy Single-IP-Management.

7
+ Supports Telnet, CLI, SNMP v1/v2c/v3, RMON and web access.

Chapter 3 Installation
3.1 Precautions
To ensure a long-term and stable performance of the Switch, please pay attention to the following
before the installation.
1) Safety Requirements
•Before cleaning the Switch, cut off the power supply. Do not clean it by the waterish cloth,
and never use any other liquid cleaning method.
•Take waterproof measures during storage, transportation and operation of the equipment.
•Use only the power cord provided with the Switch.
•Make sure the voltage of the power supply meets the requirement of the input voltage of the
Switch.
•Do not push any objects into the openings of the Switch.
•Ensure the vent hole is well ventilated and unblocked.
•Do not open or remove the cover of the Switch.
2) Location Requirements
When you choose a location for the Switch, please follow these guidelines:
•Install the Switch on a flat and stable surface that can support the entire weight of the
Switch with all fittings.
•Locate the Switch far from strong electromagnetic field generators (such as motors),
vibration, dust, and direct exposure to sunlight.
•To ensure adequate air flow around the Switch. At least 10 cm (4 inches) of space at the
front and rear of the Switch is needed for ventilation.
•Make sure that the Switch will be accessible and that the cables can be easily connected.
•Position the Switch away from water and moisture sources, be sure to provide an
acceptable temperature and humidity operating environment.

3.3 Connect to Ground
Connecting the Switch to ground is to quickly release the lightning over-voltage and over-current of
the Switch, which is also a necessary measure to protect the body from electric shock.
In different environments, the Switch may be grounded differently. The following will instruct you to
connect the Switch to the ground in two ways, connecting to the Grounding Bar or connecting to the
Ground via the power cord. Please connect the Switch to ground in the optimum way according to

your specific operation environment.
•Connecting to the Grounding Bar
If the Switch is installed in the Equipment Room, where a Grounding Bar is available, you are
recommended to connect the Switch to the Grounding Bar as shown in the following figure.
Figure 3-4
