INTRODUCTION
This chapter describes the features of the Switch and some
background information about Ethernet/Fast Ethernet
switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing
complexity of desktop computing applications are fueling the
need for high performance networks. A number of high-
speed LAN technologies have been proposed to provide
greater bandwidth and improve client/server response times.
Among them, 100BASE-T (Fast Ethernet) provides a non-
disruptive, smooth evolution from the current 10BASE-T
technology. The non-disruptive and smooth evolution nature,
and the dominating potential market base, virtually
guarantee cost effective and high performance Fast Ethernet
solutions in the years to come.
100Mbps Fast Ethernet is a new standard specified by the
IEEE 802.3 LAN committee. It is an extension of the
10Mbps Ethernet standard with the ability to transmit and
receive data at 100Mbps, while maintaining the CSMA/CD
Ethernet protocol. Since the 100Mbps Fast Ethernet is
compatible with all other 10Mbps Ethernet environments, it
provides a straightforward upgrade path and takes
advantage of the existing investment in hardware, software,
and personnel training.

Switching Technology
Another approach to pushing beyond the limits of Ethernet
technology is the development of switching technology. A
switch bridges Ethernet packets at the MAC address level of
the Ethernet protocol. It transmits packets among connected
Ethernet or Fast Ethernet LAN segments.
Switching is a cost-effective way of increasing the total
network bandwidth available to users on a local area
network. A switch divides a local area network into multiple,
separate segments. Each segment has it’s own full Ethernet
or Fast Ethernet bandwidth that doesn’t compete with the
other segments for network transmission.
The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with
any other segments, automatically forwards traffic that
needs to go from one segment to another and blocks traffic
that does not need to be transmitted. By doing this the total
network bandwidth is multiplied, while still maintaining the
same network cabling and adapter cards.
For Fast Ethernet networks, a switch is an effective way of
eliminating the problem of chaining hubs beyond the “two-
repeater limit.” A switch can be used to split parts of the
network into different collision domains, making it possible
to expand a Fast Ethernet network beyond the 205-meter
network diameter limit. Switches supporting both
traditional 10Mbps Ethernet and 100Mbps Fast Ethernet
are ideal for bridging between existing 10Mbps networks and
new 100Mbps networks.

Switching LAN technology is a marked improvement over
the previous generation of network bridges, which were
characterized by higher latencies. Today switches are an
ideal solution to most kinds of local area network congestion
problems.
Features
The DSS-5+ was designed for easy installation and high
performance in an environment where network traffic and
the number of users increases continuously.
Designed with the small and medium network in mind, the
DSS-5+ comes in a small and compact size. Whether used to
connect 10Mb and 100Mb network segments and servers
together, or to extend an existing switched network, it has
the necessary speed to do the job.
The DSS-5+ is expandable by cascading two or more
switches together. All ports support up to 200Mbps. Any
one of its five ports may be used to cascade to an additional
switch to open a Full-Duplex Fast Ethernet pipe. A single
uplink port is integrated into the DSS-5+ to negate the need
for a cross-over or other special networking cable when
cascading to another switch.
The DSS-5+ is a perfect choice for sites planning to upgrade
to Fast Ethernet in the future. Ethernet workgroups can
connect to the DSS-5+ now, and upgraded Fast Ethernet
adapters and hubs can be added anytime later without
requiring any change to the Switch or network configuration.
The Switch combine dynamic memory allocation with store-
and-forward switching to ensure that the buffer is effectively

4
allocated for each port, while controlling the data flow
between the transmit and receive nodes to guarantee against
all possible packet loss.
The Switch is an unmanaged 10/100 Fast Ethernet Switch
that offers solutions in accelerating small Ethernet
workgroup bandwidth. Other key features are:
Uplink/ MDI-II (media dependent interface) port for uplink to another
switch, hub or repeater.
Store and forward switching scheme capability. As the result of complete
frame checking and error frame filtering, this scheme prevents error
packages from transmitting among segments.
NWay Auto-negotiation for any port. This allows for auto-sensingofspeed
(10/100Mbps) thereby providing you with automatic and flexible solutions in
your network connections.
Flow control for any port. This minimizes dropped packets by sending out
collision signals when the port’s receiving buffer is full. Note that flow
control is only available in half duplex mode.
Data forwarding rate per port is at wire-speed for 100Mbps speed.
Data forwarding rate per port is at wire-speed for 10Mbps speed.
Data filtering rate eliminates all error packets, runts, etc., per port at wire-
speed for 100Mbps speed.
Data filtering rate eliminates all error packets, runts, etc., per port at wire-
speed for 10Mbps speed.

UNPACKING AND SETUP
This chapter provides unpacking and setup information for
DSS-5+.
Unpacking
Open the shipping cartons of the Switch and carefully
unpacks its contents. The carton should contain the
following items:
One DSS-5+ 5-port 10/100Mbps Dual Speed Ethernet Switch
One external power adapter
This User’s Guide
If any item is found missing or damaged, please contact your
local reseller for replacement.
Setup
The setup of DSS-5+ can be performed using the following
steps:
The surface must support at least 1.5 Kg for the Switch.
The power outlet should be within 1.82 meters (6 feet) of the Switch.
Visually inspect the DC power jack and make sure that it is fully secured to
the power adapter.
Make sure that there is proper heat dissipation from and adequate
ventilation around the Switch. Do not place heavy objects on the Switch.

IDENTIFYING EXTERNAL COMPONENTS
This section identifies all the major external components of
the DSS-5+. Both the front and rear panels are shown
followed by a description of each panel feature. The indicator
panel is described in detail in the next chapter.
Front Panel
The figure below shows the front and rear panels of the DSS-
5+ .
DSS-5+ 10/100M Dual Speed Ethernet Switch
LED Indicator Panel
Refer to the LED Indicator section for detailed
information about each of the hub’s LED indicators.
Rear Panel
DSS-5+ 10/100M Dual Speed Ethernet Switch
DC Power Jack: Power is supplied through an external AC
power adapter. Check the technical specification section for
information about the AC power input voltage.
Since the switch does not include a power switch, plugging
its power adapter into a power outlet will immediately power

8
it on.
MDI-X Jacks: Use these jacks to connect stations to the hub. These are
MDI-X(Medium-Dependent Interface, Cross-wired) jacks, which mean, you
can use ordinary straight-through twisted-pair cables to connect user
machines and servers to the switch through them. If you need to connect
another device with an MDI-Xjack, such as another switch or an Ethernet or
Fast Ethernet hub, you should use a crossover cable, or make the connection
using the MDI-II jack (described below). Please see www.dlink.comformore
information on cross-over cables and cascading switches.
Uplink Jack(s) (MDI-II ): Use this jack to connect stations to the hub. This
is a MDI-II (Medium-dependent Interface, straight-wired) jack,whichmeans
you can connect the DSS-5+ to a device with a MDI-Xport (like a hub or
switch) using an ordinary straight-through cable.
PLEASE NOTE: When using the MDI-II to cascade to a
switch or hub, the MDI-X directly next to it will be
disabled automatically. A maximum of 5 devices can
be attached to the switch at anytime.
LED Indicators
Power Indicator (PWR)
This LED will light a solid green when the unit is
receiving power.
Full-Duplex/Collision (Full-Duplex/Collision)
This LED indicator will light a solid green when a
respective port is in full duplex (FDX) mode. As collisions
occur on the respective port it will blink. Collisions are
normal in an Ethernet network.
100M Link/Activity, 10M Link/Activity
(100M LINK/ACT (green), 10LINK/ACT (amber))
This indicator lights green when the port is connected to a
100Mbps Fast Ethernet station. The indicator blinks

9
green as Fast Ethernet data is transmitted or received.
The indicator lights amber when the port is connected to
a 10Mbps Ethernet station or other network device. The
indicator blinks amber as Ethernet data is transmitted or
received.
