Safety Instructions 
Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential 
damage. Throughout this safety section, the caution icon  (       ) is used to indicate cautions and precautions that you need 
to review and follow. 
 
Safety Cautions 
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions. 
Observe and follow service markings. Do not service any product except as explained in your system documentation. 
Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to an 
electrical shock. Only a trained service technician should service components inside these compartments. 
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your 
trained service provider: 
– The power cable, extension cable, or plug is damaged. 
– An object has fallen into the product. 
– The product has been exposed to water. 
– The product has been dropped or damaged. 
– The product does not operate correctly when you follow the operating instructions. 
 Keep your system away from radiators and heat sources. Also, do not block cooling vents. 
 Do not spill food or liquids on your system components, and never operate the product in a wet environment. If 
the system gets wet, see the appropriate section in your troubleshooting guide or contact your trained service 
provider. 
 Do not push any objects into the openings of your system. Doing so can cause a fire or an electric shock by 
shorting out interior components. 
 Use the product only with approved equipment. 
 Allow the product to cool before removing covers or touching internal components. 
 Operate the product only from the type of external power source indicated on the electrical ratings label. If you 
are not sure of the type of power source required, consult your service provider or local power company. 
 To help avoid damaging your system, be sure the voltage selection switch (if provided) on the power supply is set 
to match the power available at your location: 
– 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South 
Korea and Taiwan. 
– 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan. 
– 230 V/50 Hz in most of Europe, the Middle East, and the Far East. 
 Also be sure that attached devices are electrically rated to operate with the power available in your location. 
 Use only approved power cable(s). If you have not been provided with a power cable for your system or for any 
AC-powered option intended for your system, purchase a power cable that is approved for use in your country. 
The power cable must be rated for the product and for the voltage and current marked on the products electrical 
ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product. 
 To help prevent an electric shock, plug the system and peripheral power cables into properly grounded electrical 
outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter 
plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with 
properly grounded plugs. 
 Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged 
into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension 
cable or power strip. 
 To help protect your system from sudden, transient increases and decreases in electrical power, use a surge 
suppressor, line conditioner, or uninterruptible power supply (UPS). 
 Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over. 
Be sure that nothing rests on any cables. 
 Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. 
Always follow your local/national wiring rules.  
						

							D-Link DGS-1005D Unmanaged Gigabit Ethernet Switch 
vi   When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe 
the following guidelines: 
– Install the power supply before connecting the power cable to the power supply. 
– Unplug the power cable before removing the power supply. 
– If the system has multiple sources of power, disconnect power from the system by unplugging all power cables    
from the power supplies. 
 Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid 
sudden stops and uneven surfaces. 
 
 General Precautions for Rack-Mountable Products 
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation 
accompanying the system and the rack for specific caution statements and procedures. 
Systems are considered to be components in a rack. Thus, component refers to any system as well as to various 
peripherals or supporting hardware. 
 
 
CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause 
the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, 
always install the stabilizers before installing components in the rack.  
After installing system/components in a rack, never pull more than one component out of the 
rack on its slide assemblies at one time. The weight of more than one extended component 
could cause the rack to tip over and may result in serious injury. 
 
 Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that 
the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers 
for joined multiple racks before working on the rack.
 
 Always load the rack from the bottom up, and load the heaviest item in the rack first. 
 Make sure that the rack is level and stable before extending a component from the rack. 
 Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the 
slide rails can pinch your fingers. 
 After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the 
component into the rack. 
 Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not 
exceed 80 percent of the branch circuit rating. 
 Ensure that proper airflow is provided to components in the rack. 
 Do not step on or stand on any component when servicing other components in a rack. 
 
  
 
NOTE: A qualified electrician must perform all connections to DC power and to safety grounds. 
All electrical wiring must comply with applicable local or national codes and practices. 
 CAUTION: 
Never defeat the ground conductor or operate the equipment in the absence of a 
suitably installed ground conductor. Contact the appropriate electrical inspection authority or an 
electrician if you are uncertain that suitable grounding is available. 
 CAUTION: 
The system chassis must be positively grounded to the rack cabinet frame. Do not 
attempt to connect power to the system until grounding cables are connected. Completed power 
and safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard 
will exist if the safety ground cable is omitted or disconnected.

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.

Ethernet 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 are proposed to provide greater bandwidth and 
improve client/server response times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive, smooth 
evolution from 10BASE-T technology.  
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 Carrier Sense Multiple 
Access with Collision Detection (CSMA/CD) Ethernet protocol.  
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 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with 
all 10Mbps and 100Mbps 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 are essential to coping with the network bottlenecks 
that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. 
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 subnetworks.  
Gigabit Ethernet enables fast optical fiber connections to support 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. 
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage 
of today and tomorrow’s rapidly improving switching and routing internetworking technologies.  
802.1p and QoS 
The DGS-1005D Switch supports 802.1p priority queuing Quality of Service. The implementation of QoS (Quality of 
Service) and benefits of using 802.1p priority queuing are described here.  
Advantages of QoS  
QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving 
bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet 
Protocol), web browsing applications, file server applications or video conferencing. Not only can a larger bandwidth be 
created, but other less critical traffic can be limited, so bandwidth can be saved. The Switch has separate hardware queues 
on every physical port to which packets from various applications are mapped to and assigned a priority. The illustration 
below shows how 802.1P priority queuing is implemented on the Switch. The eight IEEE 802.1P priority levels defined by 
the standard are mapped to the four class queues used in the Switch.   
						

							D-Link DGS-1005D Unmanaged Gigabit Ethernet Switch 
 
 
Mapping QoS on the Switch 
The picture above shows the default priority setting for the Switch. Class-3 has the highest priority of the four priority 
queues on the Switch. In order to implement QoS, the user is required to instruct the Switch to examine the header of a 
packet to see if it has the proper identifying tag tagged. Then the user may forward these tagged packets to designated 
queues on the Switch where they will be emptied, based on priority.  
The DUT support strict mode for 802.1p QoS. The untagged pkt will follow the priority 0 to work (i.e. class 1). 
                                                                                                                                                           
Understanding QoS 
The Switch has four priority queues. These priority queues are labeled as 3, the high queue to 0, the lowest queue. The 
eight priority tags, specified in IEEE 802.1p are mapped to the Switchs priority tags as follows: 
 Priority 0 is assigned to the Switchs Q1 queue. 
 Priority 1 is assigned to the Switchs Q0 queue. 
 Priority 2 is assigned to the Switchs Q0 queue. 
 Priority 3 is assigned to the Switchs Q1 queue. 
 Priority 4 is assigned to the Switchs Q2 queue. 
 Priority 5 is assigned to the Switchs Q2 queue. 
 Priority 6 is assigned to the Switchs Q3 queue. 
 Priority 7 is assigned to the Switchs Q3 queue. 
The Switch uses strict priority for Scheduling. Strict priority-based scheduling, any packets residing in the higher priority 
queues are transmitted first. 
 
D-Link’s Green Technology 
D-Link’s Green Technology implements special power-saving features under speed at 1000Mbps that detect cable length 
and link status and adjust power usage accordingly.   
Green Ethernet Technology saves energy in two specific ways: 
Method 1: 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, Green Ethernet Technology will enter a sleep mode, drastically reducing power used for that port. 
Method 2: D-Link Green Ethernet detects the length of connected Ethernet cable and adjusts power usage accordingly 
without affecting performance.  This way, a port connected to a less than 20m cable only uses as much power as it needs, 
instead of using full power, which is only needed for 100m cables. 
 
Switching Technology 
Another key development pushing the limits of Ethernet technology is in the field of switching technology. A switch 
bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or fast 
Ethernet LAN segments. 
Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A 
switch increases capacity and decreases network loading by making it possible for a local area network to be divided into 
different segments that do not compete with each other for network transmission capacity, decreasing the load on each 
segment. 
The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one 
segment to another (from one port to another) is automatically forwarded by the switch, without interfering with any other  
						

							D-Link DGS-1005D Unmanaged Gigabit Ethernet Switch 
  segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling 
and adapter cards. 
For Fast Ethernet or Gigabit Ethernet networks, a Switch is an effective way of eliminating problems of chaining hubs 
beyond the “two-repeater limit.” A Switch can be used to split parts of the network into different collision domains, for 
example, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 
100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also 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. Routers have also been used to segment local area networks, but the cost of a router and 
the setup and maintenance required make routers relatively impractical. Today’s Switches are an ideal solution to most 
kinds of local area network congestion problems. 
Switch Description 
The DGS-1005D Switch is equipped with five ports providing dedicated 10, 100, or 1000 Mbps bandwidth. These ports 
can be used for connecting PCs, printers, servers, routers, Switches, hubs, and other network devices. The five multi-speed 
ports use standard twisted pair cabling and are ideal for segmenting networks into small, connected subnets. Each port can 
support up to 2000 Mbps of throughput in full-duplex mode. This stand-alone Switch enables the network to use some of 
the most demanding multimedia and imaging applications concurrently with other user applications without creating 
bottlenecks. 
Features

performance in an environment where traffic on the network and the number of users increase continuously.
