Safety Instructions (continued)

• To help prevent 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 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 b odily injury und er
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 DES-1048G Unmanaged Layer 2 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.

NOTE: A qualified electricia n 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 t he appro priate electric al
inspection authority or an electrician if you are unc ertain that suitable grounding i s
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 and
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 is essential to coping with the network
bottlenecks that frequently develop as computers and th eir busses get faster and more users use applicatio ns 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.

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

1

D-Link DES-1048G Unmanaged Layer 2 Ethernet Switch

network to be divided into different segments which don’t compete with each other for network transmission
capacity, giving a decreased load on each.

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 au tomatically forwarded by the switch, without interf ering
with any other segments (ports). This allows the total network capacity to be multiplied, while still main taining
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 collisio n
domains, for example, making it possible to expand your Fast Ethern et 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 10M bp s net w o rks 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 DES-1048G is a stand-alone unmanaged switch. It is equipped with forty-eigh t ports provid ing dedicated 10
or 100 Mbps bandwidth. These ports can be used for connecting PCs, servers, and hubs. The forty-eight dual
speed ports use standard twisted-pair cabling and are ideal for segmenting networks into small, connected
subnets. Each port can support up to 200 Mbps of throughpu t in full duplex mode. In addition, the Switch is
equipped with two Mini-GBIC fiber optic uplink ports enabling convenient access to a server or network
backbone for all the clients served by the Switch. 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. The built-in console interface can be used to individually con figure each po rt for Speed, Fu ll or Half
duplex operation, and IEEE 802.3x Flow Control in full duplex mode.

D-Link DES-1048G Unmanaged Layer 2 Ethernet Switch

Glossary

1000BASE-SX – 1000Mbps Ethernet implementation over fiber-optic cable, intended for shorter distances,
such as within a building.

1000BASE-LX – 1000Mbps Ethernet implementation over fiber-optic cable, for longer distances, such as a
college campus.

100BASE-TX – 100Mbps Ether net implementation over Category 5 an d Type 1 t wis t ed pai r ca bl i n g.
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 – The part of a network used as the primary path for transporting traffic
backbone port – A port which does not learn device addresses, and which receives all frames with an

unknown address. Backbone ports are normally used to conn ect the switch to the b ackbone of your network.
Note that backbone ports were formerly known as designated downlink ports.

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

baud rate – The switching speed of a line. Also known as line speed between network segments.
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.

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 high­performance 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/ C D net work a ccess m e thod.
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 system 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 transmitted and received, but not at the same time.

Contrasts with full duplex.

D-Link DES-1048G Unmanaged Layer 2 Ethernet Switch

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 allo wi n g com munication 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.

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 shou ld 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 which 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 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 which 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.
