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-T (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.
D-Link’s Green Technology
D-Link’s Green Technology implements special power-saving features
under speed at 100Mbps that link status and adjust power usage
accordingly. Further, D-Link Green implements the newly ratified IEEE
802.3az Energy Efficient Ethernet standard for reducing energy
consumption of network links during periods of low utilization by
transitioning interfaces into low-power state without interrupting the
network connection.
•IEEE 802.3az Energy-Efficient Ethernet (EEE):
It is the first standard in the history of Ethernet to address proactive
reduction in energy consumption for networked devices. The IEEE 802.3
EEE standard defines mechanisms and protocols intended to reduce the
energy consumption of network links during periods of low utilization, by

3
transitioning interfaces into a low-power state without interrupting the
network connection.
•Power Saving Technology:
Power saving by link status. If there is no link on a port, such as when
there is no computer connected to the port or the connected computer is
powered off, D-Link’s Green Technology will enter a "sleep mode",
drastically reducing power used for that port.
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.
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
considerably reduces the likelihood of traffic congestion.
For Ethernet networks, a switch is an effective way of eliminating the

4
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.
Features
The GO-SW-5E is a high performance switch designed specifically for
environments where traffic on the network and the number of users
increase continuously.
GO-SW-5E implements D-Link’s Green Technology special power-saving
features under speed at 100Mbps that link status and adjust power usage
accordingly. Furthermore, D-Link Green implements the newly ratified
IEEE 802.3az Energy Efficient Ethernet standard for reducing energy
consumption of network links during periods of low utilization by
transitioning interfaces into low-power state without interrupting the
network connection.
The GO-SW-5E, with its small, compact size, was specifically designed
for small to mid-sized workgroups. The GO-SW-5E 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 GO-SW-5E 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

5
the server.
The GO-SW-5E is scalable, allowing two or more GO-SW-5E 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 GO-SW-5E is the perfect choice for a department or office planning
to upgrade to Fast Ethernet. The GO-SW-5E can accommodate 10Mbps
or 100Mbps devices, providing a flexible solution for existing (10Mbps)
Ethernet workgroups.
The GO-SW-5E 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 GO-SW-5E is an unmanaged 10/100Mbps Fast Ethernet switch that
offers solutions for the accelerating bandwidth needs of small Ethernet
workgroups.
Other key features include:
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.

CONNECTING THE SWITCH
PC to GO-SW-5E
A computer can be connected to the GO-SW-5E 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 five GO-
SW-5E 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
GO-SW-5E’s conditions and connections.
Hub to GO-SW-5E
A hub (10 or 100BASE-TX) can be connected to the GO-SW-5E 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
GO-SW-5E.
GO-SW-5E to other devices
The GO-SW-5E 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 cable must be used for
100Mbps operation. The connection can be accomplished from any (MDI-
X) port on the GO-SW-5E to any of the 10Mbps or 100Mbps (MDI-X)
ports on another switch or other devices.

10
Port Speed & Duplex Mode
After plugging the selected cable to a specific port, the system uses auto-
negotiation to determine the transmission mode, auto-detecting the
network speed (10Mbps or 100Mbps) for any new twisted-pair connection.
If the attached device does not support auto-negotiation or has auto-
negotiation disabled, an auto-sensing process is initiated to select the
speed and half-duplex mode is selected.
