Safety Instructions (continued)

•

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 product's 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.

• 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 Rack­Mountable 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.

vii

D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch

Safety Instructions (continued)

• 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.

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.

Switch Description

The 16-port DGS-1016D and 24-port DGS-1024D 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 required. Just power on the Switch and connect the cables.
Keep in mind however that the standard rules of Ethernet regarding cable
length apply to this and all Ethernet devices. The length of an Ethernet
cable from one device to another cannot exceed 100 meters (or 300 feet).

10

Switch Features

The DGS-1016D 16-Port and DGS-1024D 24-port Switches do not require
any management. Both Switches are designed for easy installation,
flexibility and high performance. Connect devices to the Switch as the
scale and volume of network traffic increases.

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
essential to coping with the network bottlenecks that frequently develop as
computers and their bus speeds 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
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.

802.1P and QoS

The DGS-1024D and DGS-1016D Switches support 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

12

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.

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 Switch's priority tags as follows:

• Priority 0 is assigned to the Switch's Q1 queue.

• Priority 1 is assigned to the Switch's Q0 queue.

• Priority 2 is assigned to the Switch's Q0 queue.

• Priority 3 is assigned to the Switch's Q1 queue.

• Priority 4 is assigned to the Switch's Q2 queue.

• Priority 5 is assigned to the Switch's Q2 queue.

• Priority 6 is assigned to the Switch's Q3 queue.

13

• Priority 7 is assigned to the Switch's Q3 queue.
The Switch uses strict priority for Scheduling. Strict priority-based

scheduling, any packets residing in the higher priority queues are trans­mitted first.

14

Front-Panel Components

Note: The Switch illustrations used for this manual depict only the model
DGS-1016D Switch.

On the front panel of the Switch you will see the following.

• LED status indicators

• 16 Auto-Negotiating 10/100/1000Mbps po rts on the DGS-1016D

• 24 Auto-Negotiating 10/100/1000Mbps po rts on the DGS-1024D

Front Panel View of the Switch

LED Indicators

The LED indicators of the Switch include a Power status indicator, one
Link/Act indicator for each port as well as one speed 100/1000Mbps
indicator for each port. When the Switch is powered on or restarted, it
initiates a diagnostic function as part of the boot up process. The speed
indicators are also used to display cable diagnostic information when the
Switch boots up.

LED Indicators

15

Cable Diagnostic

Upon booting up the Switch, a Cable Diagnostic is used to detect three
problems that may prevent successful connection. This feature operates
only on ports that are connected to 1000Mbps devices. If there are
problems on a port connected to a Gigabit Ethernet device (1000Mbps),
try restarting the Switch and watch the speed (100/1000Mbps) LED
indicators to determine is the problem is a fault in the cable or connecting
hardware. For ports operating at 10 or 100Mbps, the LED indicators can
be used for less specific troubleshooting.

The faults detected by the cable diagnostic for 1000Mbps operation are as
follows:

• Open circuit - a lack of continuity between the pins at each end of the

Ethernet cable or a disconnected cable.

• Short circuit - two or more conductors short-circuited.

• Connectivity is checked for each of the eight wires of a cable to

ensure its capability for running 1000Mbps.

During the diagnostic, each port is scanned to determine if the Ethernet
cable and connectors is in good working order. During the diagnostic
process the speed LED for each port blinks green in sequential order. This
port scan takes about 3 seconds. If a cable fault is detected, the
corresponding port’s speed LED will light amber for 5 seconds. The
Switch is then reset for normal operation. It takes about 2 seconds for the
Switch to reset. The entire Cable Diagnostic process takes about 10
seconds from the time the Switch is powered on.

The table below summarizes Cable Diagnostic information.

NOTE: the cable diagnostic function does not
detect the length of Ethernet cabling. Remember
that the length of cabling between two Ethernet
devices may not exceed 100 meters (or 300 feet).

10BASE-T – The IEEE 802.3 specification for Ethernet over Unshielded Twisted Pair

(UTP) cabling.
aging – The automatic removal of dynamic entries from the Switch Database which

have timed-out and are no longer valid.
ATM – Asynchronous Transfer Mode. A connection oriented transmission protocol

based on fixed length cells (packets). ATM is designed to carry a complete range of
user traffic, including voice, data, and video signals.

auto-negotiation – A feature on a port, which allows it to advertise its capabilities for
speed, duplex, and flow control. When connected to an end station that also supports
auto-negotiation, the link can self-detect its optimum operating setup.

backbone port – A port that does not learn device addresses, and that receives all
frames with an unknown address. Backbone ports are normally used to connect the
Switch to the backbone of your network. Note that backbone ports were formerly
known as designated downlink ports.

backbone – The part of a network used as the primary path for transporting traffic
between network segments.

Bandwidth – Information capacity, measured in bits per second, that a channel can
transmit. The bandwidth of Ethernet is 10Mbps. the bandwidth of Fast Ethernet is
100Mbps.

baud rate – The switching speed of a line. Also known as line speed.
BOOTP – The BOOTP protocol allows you to automatically map an IP address to a

given MAC address each time a device is started. In addition, the protocol can assign
the subnet mask and default gateway to a device.

bridge – A device that interconnects local or remote networks no matter what higher
level protocols are involved. Bridges form a single logical network, centralizing
network administration.

broadcast – A message sent to all destination devices on the network.
broadcast storm – Multiple simultaneous broadcasts that typically absorb available

network bandwidth and can cause network failure.
console port – The port on the Switch accepting a terminal or modem connector. It

changes the parallel arrangement of data within computers to the serial form used on
data transmission links. This port is most often used for dedicated local management.

31

CSMA/CD – Channel access method used by Ethernet and IEEE 802.3 standards, in
which devices transmit only after finding the data channel clear for some period of time.
When two devices transmit simultaneously, a collision occurs and the colliding devices
delay their retransmissions for a random amount of time.

data center switching – The point of aggregation within a corporate network where a
switch provides high-performance access to server farms, a high-speed backbone
connection, and a control point for network management and security.

Ethernet – A LAN specification developed jointly by Xerox, Intel, and Digital
Equipment Corporation. Ethernet networks operate at 10Mbps using CSMA/CD to run
over cabling.

Fast Ethernet – 100Mbps technology based on the Ethernet/CD network access
method.

Flow Control – (IEEE 802.3z) A means of holding packets back at the transmit port of
the connected end station. Prevents packet loss at a congested switch port.

forwarding – The process of sending a packet toward its destination by an
internetworking device.

Full-duplex – A syste m that allows packets to be transmitted and received at the same
time and, in effect, doubles the potential throughput of a link.

Half-duplex – A system that allows packets to be tran smitted and received, but not at
the same time. Contrast with full-duplex.

IP address – Internet Protocol address. A unique identifier for a device attached to a
network using TCP/IP. The address is written as four octets separated with full-stops
(periods), and is made up of a network section, an optional subnet section and a host
section.

IPX – Internetwork Packet Exchange. A protocol allowing communication in a
NetWare network.

LAN – Local Area Network. A network of connected computing resources (such as
PCs, printers, servers) covering a relatively small geographic area (usually not larger
than a floor or building). Characterized by high data rates and low error rates.

latency – The delay between the time a device receives a packet and the time the packet
is forwarded out of the destination port.

line speed – See baud rate.
main port – The port in a resilient link that carries data traffic in normal operating

conditions.
MDI – Medium Dependent Interface. An Ethernet port connection where the

transmitter of one device is connected to the receiver of another device.
MDI-X – Medium Dependent Interface Cross-over. An Ethernet port connection where

the internal transmit and receive lines are crossed.
MIB – Management Information Base. Stores a device’s management characteristics

and parameters. MIBs are used by the Simple Network Management Protocol (SNMP)
to contain attributes of their managed systems. The Switch contains its own internal
MIB.

multicast – Single packets copied to a specific subset of network addresses. These
addresses are specified in the destination-address field of the packet.

32

protocol – A set of rules for communication between devices on a network. The rules
dictate format, timing, sequencing, and error control.

resilient link – A pair of ports that can be configured so that one will take over data
transmission should the other fail. See also main port and standby port.

RJ-45 – Standard 8-wire connectors for IEEE 802.3 10BASE-T networks.
RMON – Remote Monitoring. Subset of SNMP MIB II, which allows monitoring and

management capabilities by addressing up to ten different groups of information.
RPS – Redundant Power System. A device that provides a backup source of power

when connected to the Switch.
server farm – A cluster of servers in a centralized location serving a large user

population.
SLIP – Serial Line Internet Protocol. A protocol that allows IP to run over a serial line

connection.
SNMP – Simple Network Management Protocol. A protocol originally designed to be

used in managing TCP/IP internets. SNMP is presently implemented on a wide range of
computers and networking equipment and may be used to manage many aspects of
network and end station operation.

Spanning Tree Protocol – (STP) A bridge-based system for providing fault tolerance
on networks. STP works by allowing you to implement parallel paths for network
traffic, and to ensure that redundant paths are disabled when the main paths are
operational and enabled if the main paths fail.

stack – A group of network devices that are integrated to form a single logical device.
standby port – The port in a resilient link that will take over data transmission if the

main port in the link fails.
switch – A device that filters, forwards, and floods packets based on the packet’s

destination address. The Switch learns the addresses associated with each switch port
and builds tables based on this information to be used for the switching decision.

TCP/IP – A layered set of communications protocols providing Telnet terminal
emulation, FTP file transfer, and other services for communication among a wide range
of computer equipment.

Telnet – A TCP/IP application protocol that provides virtual terminal service, letting a
user log in to another computer system and access a host as if the user were connected
directly to the host.

TFTP – Trivial File Transfer Protocol. Allows you to transfer files (such as software
upgrades) from a remote device using your switch’s local management capabilities.

UDP – User Datagram Protocol. An Internet standard protocol that allows an
application program on one device to send a datagram to an application program on
another device.

VLAN – Virtual LAN. A group of location- and topology-independent devices that
communicate as if they are on a common physical LAN.

VLT – Virtual LAN Trunk. A Switch-to-Switch link which carries traffic for all the
VLANs on each Switch.
