1INTRODUCTION
OVERVIEW
The DG-FS4528E switch is a intelligent switch with 24 10/100BASE-T ports, and
four Gigabit combination ports1that are comprised of an RJ-45 port and an SFP
transceiver slot. There is also 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 empower
multimedia applications with multicast switching and CoS services.

SWITCH ARCHITECTURE
This switch employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all
ports. This 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
This 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 a switch, you can make a direct connection to
the RS-232 console port (out-of-band), or you can manage it through a network
connection (in-band) using Telnet, the on-board Web agent, or Windows-based
network management software.
For a detailed description of the switch’s software features, refer to the
Management Guide.
DESCRIPTION OF HARDWARE
10/100BASE-T PORTS
This switch contains 24 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or
full duplex. Because all ports on both switches support automatic MDI/MDI-X
operation, you can use straight-through cables for all network connections to
PCs or servers, or to other switches or hubs. (See “Twisted-Pair Cable and Pin
Assignments” on page 41.)
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.

C HAPTER 1 | Introduction
Description of Hardware
– 15 –
Each port also supports auto-negotiation of flow control, so the switch can
automatically prevent port buffers from becoming saturated.
SFP SLOTS
The Small Form Factor Pluggable (SFP) transceiver slots are shared with four RJ-
45 ports (combination ports). In its default configuration, if an SFP transceiver
(purchased separately) is installed in a slot and has a valid link on its 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 LEDs, which are located on the front panel for easy viewing, are shown
below and described in the following table.

POWER SUPPLY SOCKET
There is one standard power socket on the rear panel of the switch for the AC
power cord.
Figure 4: Power Supply Socket
APPLICATION EXAMPLES
This switch is an excellent choice for mixed 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 to
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.
Some typical application examples are described in this section.
NETWORK AGGREGATION PLAN
With 24 parallel bridging ports (i.e., 24 distinct collision domains), the switch can
collapse a complex network down into a single efficient bridged node, increasing
overall bandwidth and throughput.
In the figure below, the 10/100BASE-TX ports on the switch are providing
100 Mbps connectivity through layer 2 switches. In addition, the switch is also
connecting several servers at 1000 Mbps.

Figure 5: Network Aggregation Plan
REMOTE CONNECTION WITH FIBER CABLE
Fiber optic technology allows for longer cabling than any other media type. A
1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a
1000BASE-LX (SMF) link up to 10 km, and a 1000BASE-LH link up to 70 km.
This allows the switch to serve as a collapsed backbone, providing direct
connectivity for a widespread LAN.
A 1000BASE-SX SFP transceiver can be used for a high-speed connection
between floors in the same building, a 1000BASE-LX SFP transceiver can be
used to connect to other buildings in a campus setting, and a 1000BASE-LH SFP
transceiver can be used for a long-haul connection to a remote site.
The figure below illustrates the switch connecting multiple segments with fiber
cable.

2INSTALLING THE SWITCH
SELECTING ASITE
Switch units can be mounted in a standard 19-inch equipment rack or on a flat
surface. Be sure to follow the guidelines below when choosing a location.
The site should:
be at the center of all the devices you want to link and near a power
outlet.
be able to maintain its temperature within 0 to 55 °C (32 to 130 °F)
and its humidity within 5% to 95%, non-condensing
provide adequate space (approximately two inches) on all sides for
proper air flow
be accessible for installing, cabling and maintaining the devices
allow the status LEDs to be clearly visible
Make sure twisted-pair cable is always routed away from power lines,
fluorescent lighting fixtures and other sources of electrical interference,
such as radios and transmitters.
Make sure that a separate grounded power outlet that provides 100 to 240
VAC, 50 to 60 Hz, is within 2.44 m (8 feet) of each device and is powered
from an independent circuit breaker. As with any equipment, using a filter or
surge suppressor is recommended.

ETHERNET CABLING
To ensure proper operation when installing the switch into a network, make sure
that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T
operation. Check the following criteria against the current installation of your
network:
Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP)
cables with RJ-45 connectors; Category 3 or better for 10BASE-T, Category
5 or better for 100BASE-TX, and Category 5 or better for 1000BASE-T.
Protection from radio frequency interference emissions
Electrical surge suppression
Separation of electrical wires (switch related or other) and electromagnetic
fields from data based network wiring
Safe connections with no damaged cables, connectors or shields

MOUNTING
The switch units can be mounted in a standard 19-inch equipment rack or on a
desktop or shelf. Mounting instructions for each type of site follow.
RACK MOUNTING
Before rack mounting the switch, pay particular attention to the following
factors:
Temperature: Since the temperature within a rack assembly may be
higher than the ambient room temperature, check that the rack-
environment temperature is within the specified operating temperature
range. (See page 48.)
Mechanical Loading: Do not place any equipment on top of a rack-
mounted unit.
Circuit Overloading: Be sure that the supply circuit to the rack assembly
is not overloaded.
Grounding: Rack-mounted equipment should be properly grounded.
Particular attention should be given to supply connections other than direct
connections to the mains.
To rack-mount devices:
1. Attach the brackets to the device using the screws provided in the Bracket
Mounting Kit.
