Introduction
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need
for high performance networks. 100BASE-TX (Fast Ethernet) provides a cost-effective and high-performance solution for
small workgroups, SMBs (Small to Medium Businesses), and any network supporting bandwidth-intensive applications.
Fast Ethernet technology operates at 10 times the speed of traditional Ethernet, offering maximum performance and
enhanced capability for existing Ethernet-based networks.
100Mbps Fast Ethernet is a 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 and takes advantage of the existing investment in hardware, software, and personnel
training.
Switching Technology
Switching is a cost-effective way of increasing the total network capacity available to users on a LAN. If an Ethernet
network begins to display symptoms of congestion, low throughput, slow response times, and high rates of collision,
installing a switch to a network can preserve much or all of the existing network’s cabling and workstation interface card
infrastructure, while still greatly enhancing the throughput for users. A switch is a viable solution even if demanding
applications, such as multimedia production and video conferencing, are on the horizon. The most promising techniques,
as well as the best return on investment, could well consist of installing the right mixture of Ethernet switches.
A switch increases capacity and decreases network loading by dividing a local area network into different LAN
segments. Dividing a LAN into multiple segments is one of the most common ways of increasing available bandwidth.
If segmented correctly, most network traffic will remain within a single segment, enjoying the full-line speed bandwidth
of that segment.

Section 1 - Product Overview
Switches provide full-line speed and dedicated bandwidth for all connections. This is in contrast to hubs, which use the
traditional shared networking topology, where the connected nodes contend for the same network bandwidth. When
two switching nodes are communicating, they are connected with a dedicated channel between them, so there is no
contention for network bandwidth with other nodes. As a result, the switch reduces considerably, the likelihood of traffic
congestion.
For 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
your Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches supporting
both 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and
newer 100Mbps networks.
Switching LAN technology is a marked improvement over the previous generation of network hubs and bridges, which
were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of
a router, the setup and maintenance required, make routers relatively impractical. Today switches are an ideal solution
to most kinds of local area network congestion problems.

Section 1 - Product Overview
Features
• The DES-1108 is a high performance switch designed specifically for environments where traffic on the
network and the number of users increase continuously.
• The DES-1108, with its small, compact size, was specifically designed for small to mid-sized workgroups.
The DES-1108 can be installed where space is limited; moreover, it provides immediate access to a
rapidly growing network through a wide range of user-reliable functions.
• The DES-1108 is ideal for deployment with multiple high-speed servers for 10Mbps or 100Mbps shared-
bandwidth workgroups. With the highest bandwidth at 200Mbps (100Mbps full-duplex mode), any port
can provide workstations with a congestion-free data pipe for simultaneous access to the server.
• The DES-1108 is scalable, allowing two or more DES-1108 switches to be cascaded together. Since all
ports support 200Mbps, any one of its five ports may be used to cascade to an additional switch to open
a Full-Duplex Fast Ethernet pipe.
• The DES-1108 is the perfect choice for a department or office planning to upgrade to Fast Ethernet.
The DES-1108 can accommodate 10Mbps or 100Mbps devices, providing a flexible solution for existing
(10Mbps) Ethernet workgroups.
• The DES-1108 combines dynamic memory allocation with store-and-forward switching to ensure that the
buffer is effectively allocated for each port; and it controls the data flow between the transmit and receive
nodes to guarantee against possible packet loss.
• The DES-1108 is an unmanaged 10/100Mbps Fast Ethernet switch that offers solutions for the accelerating
bandwidth needs of small Ethernet workgroups.

Section 1 - Product Overview
Other key features include:
• 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.
• Auto-MDI/MDI-X function supports automatic MDI/MDI-X crossover detection, giving true ‘plug and play’
capability—Crossover or Straight-Through CAT5 cables can be plugged into any port.
• Nway Auto-negotiation for any port. This allows for auto-sensing of speed (10/100Mbps), providing an
automatic and flexible solution for the network.
• Flow control for any port. This minimizes dropped packets by sending out collision signals when the port’s
receiving buffer is full.
• Data filtering rate eliminates all error packets, runts, etc., per port at wire-speed for 100Mbps operation
and 10Mbps operation.

Front Panel (LEDs)
Power:
This green indicator light is on when the DES-1108 is receiving power; otherwise, it is off.
Link/Activity (1-8):
This LED indicator light is green when the port is connected to a 100Mbps Fast Ethernet station. The green indicator
blinks as Ethernet data is transmitted or received. The indicator light is amber when the port is connected to a 10Mbps
Ethernet station, or other network device. The amber indicator blinks as Ethernet data is transmitted or received.

Rear Panel (Connections)
Auto MDI/MDI-X Ports:
All ports support automatic MDI/MDI-X crossover detection. The AutoMDI/MDI-X function makes it simple to connect
to the switch—just plug either a Crossover or Straight-Through CAT5 cable into any port.
DC Power Jack:
Power is supplied through an external DC power adapter. Check the technical specification section for information
about the DC power input voltage.
Since the DES-1108 does not require a power button, plugging its power adapter into a power outlet will immediately
power it on.

Section 2 - Installation
Installation
This section will explain how to connect Ethernet devices to your new D-Link switch and how to mount the switch.
Connecting the Switch
PC to DES-1108
A computer can be connected to the DES-1108 via a two-pair Category 3, 4, 5 UTP/STP Straight-Through or Crossover
cable. A computer equipped with a RJ-45 10/100Mbps port can be connected to any of the eight DES-1108 ports.
The LED indicators for the PC connection depend on the capability of the computer’s Ethernet card. If the LED indicators
are not lit after making a proper connection, check the computer’s Ethernet card, the cable, and the DES-1108’s
conditions and connections.
Hub/Switch to DES-1108
A hub (10 or 100BASE-TX) can be connected to the DES-1108 via a two-pair Category 3, 4, or 5 UTP/STP
Straight-Through or Crossover cable. For 100Mbps operation a Category 5 cable must be used. The connection is
accomplished from any port of the hub to any port of the DES-1108.
DES-1108 to Other Devices
The DES-1108 can be connected to another switch or other devices (routers, bridges, etc.) via a two-pair Category 3, 4,
5 UTP/STP Straight-Through or Crossover cable. A Category 5 (or higher) cable must be used for 100Mbps operation.
The connection can be accomplished from any (MDI-X) port on the DES-1108 to any of the 10Mbps or 100Mbps
(MDI-X) ports on another switch or other devices.
