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.
