A BOUT THE TL-SL5428
Overview
The TL-SL5428 is a Fast Ethernet switch with 24 10/100BASE-TX ports
and four Gigabit combination ports1that are comprised of an RJ-45 port
and an SFP transceiver slot. The switch also includes an SNMP-based
management agent embedded on the main board. This agent supports
both in-band and out-of-band access for managing the switch.
This switch provides a broad range of powerful features for Layer 2
switching, delivering reliability and consistent performance for your
network traffic. It brings order to poorly performing networks by
segregating them into separate broadcast domains with IEEE 802.1Q
compliant VLANs, and empowers multimedia applications with multicast
switching and CoS services.

Switch Architecture
The TL-SL5428 switch employs a wire-speed, non-blocking switching
fabric. This permits simultaneous wire-speed transport of multiple packets
at low latency on all ports. The switch also features full-duplex capability
on all ports, which effectively doubles the bandwidth of each connection.
This switch uses store-and-forward switching to ensure maximum data
integrity. With store-and-forward switching, the entire packet must be
received into a buffer and checked for validity before being forwarded.
This prevents errors from being propagated throughout the network.
Network Management Options
The TL-SL5428 switch contains a comprehensive array of LEDs for
“at-a-glance” monitoring of network and port status. It also includes a
management agent that allows you to configure or monitor the switch
using its embedded management software, or via SNMP applications. To
manage the switch, you can make a direct connection to the RS-232
console port (out-of-band), or you can manage the switch through a
network connection (in-band) using Telnet, the on-board Web agent, or
SNMP-based network management software.
For a detailed description of the advanced features, refer to the Management
Guide.
Description of Hardware
10/100BASE-T Ports
The TL-SL5428 contains 24 10/100BASE-TX RJ-45 ports that operate at
10 Mbps or 100 Mbps, half or full duplex. The ports all support automatic
MDI/MDI-X operation, so you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs. (See
“10BASE-T/100BASE-TX Pin Assignments” on page B-2.)

D ESCRIPTION OF H ARDWARE

Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can
be selected automatically. If a device connected to one of these ports does
not support auto-negotiation, the communication mode of that port can
be configured manually.
Each port also supports auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.
SFP Slots
The TL-SL5428 contains four Small Form Factor Pluggable (SFP)
transceiver slots that are shared with four associated 1000BASE-T RJ-45
ports. If an SFP transceiver (purchased separately) is installed in a slot and
has a valid link on the port, the associated RJ-45 port is disabled and
cannot be used. The switch can also be configured to force the use of an
RJ-45 port or SFP slot, as required.
Port and System Status LEDs
The TL-SL5428 includes a display panel for key system and port
indications that simplify installation and network troubleshooting. The
LEDs, which are located on the front panel for easy viewing, are shown
below and described in the following tables.

Introduction to Switching
A network switch allows simultaneous transmission of multiple packets via
non-crossbar switching. This means that it can partition a network more
efficiently than bridges or routers. The switch has, therefore, been
recognized as one of the most important building blocks for today’s
networking technology.
When performance bottlenecks are caused by congestion at the network
access point (such as the network card for a high-volume file server), the
device experiencing congestion (server, power user, or hub) can be
attached directly to a switched port. And, by using full-duplex mode, the
bandwidth of the dedicated segment can be doubled to maximize
throughput.
When networks are based on repeater (hub) technology, the distance
between end stations is limited by a maximum hop count. However, a
switch turns the hop count back to zero. So subdividing the network into
smaller and more manageable segments, and linking them to the larger
network by means of a switch, removes this limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or
Gigabit Ethernet network to significantly boost bandwidth while using
conventional cabling and network cards.

Application Examples
The TL-SL5428 switch is not only designed to segment your network, but
also to provide a wide range of options in setting up network connections.
Some typical applications are described below.
Collapsed Backbone
The TL-SL5428 switch is an excellent choice for Ethernet, Fast Ethernet,
and Gigabit Ethernet installations where significant growth is expected in
the near future. In a basic stand-alone configuration, it can provide direct
full-duplex connections for up to 28 workstations or servers. When the
time comes for further expansion, just connect to another hub or switch
using one of the Fast Ethernet ports built into the front panel or a Gigabit
Ethernet port on a plug-in SFP transceiver.
In the figure below, the switch is operating as a collapsed backbone for a
small LAN. It is providing dedicated full-duplex connections to
workstations, power users, and servers.
