FCC Warning

This equipment has been tested and found to comply with the

regulations for a Class Bdigital device, pursuant to Part 15 of the FCC

Rules. These limits are designed to provide reasonable protection

against harmful interference when the equipment is operated in a

commercial environment. This equipment generates, uses, and can

radiate radio frequency energy and, if not installed and used in

accordance with this user’s guide, may cause harmful interference to

radio communications. Operation of this equipment in a residential

area is likely to cause harmful interference, in which case the user will

be required to correct the interference at his/her own expense.

CE Mark Warning

This is a Class Bproduct. In a domestic environment, this product

may cause radio interference, in which case the user may be required

to take adequate measures.

VCCI Warning

This is a product of VCCI Class BCompliance.

UL Warning

a) Elevated Operating Ambient Temperature-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 equipment in an

environment compatible with the manufacturer's maximum rated

ambient temperature (Tmra).

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 circuits might have on over current 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).

ABOUT THIS GUIDE

Congratulations on your purchase of the D-Link DES-1008PA, an 8-

Port 10/100Mbps Fast Ethernet Switch with 4-Port PoE. This Switch

integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network

capabilities in a highly flexible package. Port-1 to Port-4 on the switch

support Power over Ethernet (PoE), meaning it will automatically

detect the presence of an IEEE 802.3af-compliant powered device (PD)

and provide power through the port. The switch provides up to15.4 W

per PoE port and can be used to power WLAN access points, IP

phones, video cameras, and other PD devices. The Switch will

automatically detect the network appliance’s requirements, and will

supply the requiredpower to each appliance accordingly.

Purpose

This guide discusses how to install your 8-Port 10/100Mbps Fast

Ethernet Switch with 4-Port PoE.

Terms/Usage

In this guide, the term “Switch” (first letter upper case) refers to your

8-Port 10/100Mbps Fast Ethernet Switch with 4-Port PoE and

“switch” (first letter lower case) refers to other Ethernet switches.

INTRODUCTION

This chapter describes the features of the D-Link DES-1008PA Fast

EthernetPoE Switch and some background information about

Ethernet/Fast Ethernet,Switching and Power over 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

have been proposed to provide greater bandwidth and improve

client/server response times. Among them, 100BASE-TX (Fast

Ethernet) provides a non-disruptive, smooth evolution from the

current 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 CSMA/CD Ethernet protocol. Since the 100Mbps

Fast Ethernet is compatible with all other 10Mbps Ethernet

environments, it provides a straightforward upgrade and takes

advantage of the existing investment in hardware, software, and

personnel training.

Switching Technology

Another approach to pushing beyond the limits of Ethernet technology

is the development 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 dividing a local area

network into different segments, which don’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.

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, the setup and maintenance required

make routers relatively impractical. Today switches are an ideal

solution to most kinds of local area network congestion problems.
