Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static
damage, discharge static electricity from your body before you touch any of the
electronic components, such as the microprocessor. You can do so by periodically
touching an unpainted metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
1. When unpacking a static-sensitive component from its shipping carton, do
not remove the component from the antistatic packing material until you
are ready to install the component in your system. Just before unwrapping
the antistatic packaging, be sure to discharge static electricity from your
body.
2. When transporting a sensitive component, first place it in an antistatic
container or packaging.
3. Handle all sensitive components in a static-safe area. If possible, use
antistatic floor pads, workbench pads, and an antistatic grounding strap.

About This Guide
Congratulations on your purchase of the 16/24-PORT GIGABIT EASY
DESKTOP SWITCH. These devices are using compact plastic case
and are highly flexible solution for SOHO or small office customers.
Switch Description
The 16-port GO-SW-16G and 24-port GO-SW-24G Switches provide
dedicated 10, 100 or 1000 Mbps Ethernet bandwidth on each port. The
ports will automatically detect the speed, duplex and MDI/MDIX status
of the device it is connecting to, and adjust these settings accordingly.
The Switch ports can be used to network computers, printers, servers,
routers, other switches or any device equipped with an Ethernet port.
For best performance, use Category 5 or better Ethernet cabling.
This stand alone Switch is very easy to set up. There is no network
management is required; simply power on the Switch and connect the
cables.

Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the
same packet structure, format, and support for CSMA/CD protocol, full
duplex, flow control, and management objects, but with a tenfold
increase in theoretical throughput over 100-Mbps Fast Ethernet and a
hundredfold increase over 10-Mbps Ethernet. Since it is compatible
with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit
Ethernet provides a straightforward upgrade without wasting a
company’s existing investment in hardware, software and trained
personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet
is necessary to coping with the network bottlenecks; more computers
and their bus speeds getting faster, and more applications generate
more traffic in the network. Upgrading key components, such as your
backbone and servers to Gigabit Ethernet can greatly improve network
response times as well as significantly speed up the traffic between
your subnets.
Gigabit Ethernet supports video conferencing, complex imaging and
similar data-intensive applications. Likewise, since data transfers occur
10 times faster than Fast Ethernet, servers outfitted with Gigabit
Ethernet NIC’s are able to perform 10 times the number of operations in
the same amount of time.
D-Link Green Technology
•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 transitioning interfaces into a low-power state
without interrupting the network connection.
•Power Saving Technology:
•Power saving by link status.
10

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.
•Power saving by cable length: 0~20m, 21~100m.
D-Link’s Green Technology detects the length of connected
Ethernet cable and adjusts power usage accordingly without
affecting performance. This way, a port connected to a 20m
cable only uses as much power as it needs, instead of using full
power, which is only needed for 100m cables.

Cable Quality
For all connections to the Switch, use these rules to determine the
•For connections to 10BASE-T and 100BASE-TX devices, use
Category 5 or 5e UTP/STP cable.
•For connections to 100BASE-TX and 1000BASE-T devices, use
Category 5e or better UTP/STP cable. All 1000BASE-T
connections operate in full duplex mode.
NOTE: All Ethernet ports auto-detect MDI/MDIX, port
speed (10, 100, 1000Mbps) and duplex of the device
connected to the Switch.
NOTE: UTP (Unshielded Twisted Pair) Ethernet
cabling is adequate for most small office environments.
More expensive STP (Shielded Twisted Pair) can also
be used, but is generally only needed where there will
be risk of strong Electromagnetic of Radio Frequency
Interference.
