1 Product Introduction
Thank you and congratulations on your purchase of D-Link EasySmart Switch Products.
D-Link's next generati on EasySmart Ethernet s witch series blends plu g-and-play simp licity with exceptional
value and reliabil ity for small and m edium-sized business ( SMB) networking. All m ode ls are housed in a new
style rack-mount metal case with easy-to-view front panel diagnostic LEDs.
The brand-new DGS-1100 series are born t o be green by design of IEEE 802.3a z Energy Eff icient Ethernet
compliant (abbreviated as EEE) and D-Link Green Techno logies. It allows sign ificant power saving during
periods of low data ac ti vit y. In most of use cases and envir onments, switches are idle i n 9 0% or more of time.
While no traffic in a short period of time, ports on DGS-1100 switch get into power saving mode automatically.
Once if a packet is rec eived, the s witch wakes and works immediately. Connecting to E EE compliant devices,
such as PCs and servers, the network can save energy without compromising any performance. While
connecting to legac y devices which do not suppor t IEEE 802.3az, D-Link Green Technologies can red uce
power consumption by detecting short cable and link-down devices.

VLAN > 802.1Q VLAN
A VLAN is a group of ports that can be anywhere in the net work, but communicate as though the y were in
the same area.
VLANs can be eas ily or gan ized t o ref lect department groups (such as R&D, M arketin g), us age gr oups ( such
as e-mail), or multicast gr oups (multimedia applications such as video conferencing), and ther efore help to
simplify network management by allo wing users to move d evices to a ne w VLAN without having to change
any physical connections.
By defau lt, 80 2.1Q VL AN is disabled. With 802.1Q VL AN ena ble d, the V LAN VID 1 is created b y default wit h
an empty VLAN name field and all ports are configured as “Untagged” members.

Appendix A - Ethernet Technology
This chapter will describe the features of the D-Link EasySmart Switch and provide some background
information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology.
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, and management objects, but with a tenfold increase in
theoretical throughput of over 100-Mbps Fast Eth ernet and a hundredfold inc rease over 10-Mbps Ethernet.
Since it is compatible with all 10-Mbps and 100-Mbps Ethernet en vironments, Gigabit Ethernet provides a
straightforward upgrade wit hout was ti ng existing investments in hardware, software, or trained personnel.
The increased spe ed and extra bandwidth off ered by Gigabit Ethernet is es sential to help solving network
bottlenecks that f requently develop as more advance d computer users and ne wer applications continue to
demand greater network resourc es. U pgrading k e y components , such as backbone connections and ser vers
to Gigabit Ethernet techn ology c an great l y improve networ k response t imes as well as s ignif icantl y speed up
the traffic between subnets.
Gigabit Ethernet enabl es fast optica l fiber connecti ons to suppor t video conferenc ing, com plex imaging, and
similar data-intensive applications. Likewise, since data transfer s occur 10 times faster than Fast E thernet,
servers outfitted with Gigabit Ethernet NIC’s ar e able to perform 10 tim es the number of operations in the
same amount of time.
In addition, the phenomenal bandwidth d elivered by Gigabit Ethernet is the mos t cost-effective method to
take advantage of today and tomorrow’s rapidly improving switching and routing internetworking
technologies. And with expected advances in the coming years in silicon technology and digital signal
processing that will enabl e Gigab it Eth ernet to eventually operate over unshielded twisted-pair (UTP) cabling,
outfitting your net work with a powerful 1000-Mbps-capable backbone/s erver connection whic h will create a
flexible foundation for the next generation of network technology products.
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 provid e gr eate r ban d width a nd improve client/server res p ons e times. Among them, 100 B AS E -T
(Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. The
non-disruptive and sm ooth evolution nature, a nd the dominatin g potential mark et base, virtually guar antees
cost-effective and high performance Fast Ethernet solutions.
100Mbps Fast Ethernet is a standard specified b y the IEEE 802.3 LAN c ommittee. It is an ext ension of the
10Mbps Ethernet sta ndard with the ability to trans mit and receive data at 100M bps, while maintaining the
CSMA/CD Ethernet protoc ol. S ince the 1 00Mbps F ast Etherne t is com patible with a ll ot her 10Mbps Ether net
environments, it pro vides a straightf orward upgrade a nd utilizes exist ing investments in har dware, software,
and personnel training.
Switching Technology
Another approach to push beyond the limits of Ethernet technology is the development of switching
technology. A switch bridges Ethernet packets at the MAC address le ve l of the Et h ernet protocol transmitting
among connected Ethernet or Fast Ethernet LAN segments.
Switching is a cost-effective wa y of increasing the total n etwork capacity avai lable to users on a local area
network. A switch increases capacity and decre ases network loading by d ividing a local area network into
different segments which won’t compete with each other for network transmission capacity.
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. By doing this the total network capacity is multiplied, while still maintaining the same network
cabling and adapter cards.

Appendix C – Rack mount Instructions
Safety Instructions - Rack Mount Instructions - The following or similar rack-mount instructions are included
with the installation instructions :
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should be
given to installing the equ ip ment in an environment compatible with the maximum ambient temperature (Tma)
specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit (e.g. use
of power strips).
