CE Mark Warning
This is a Class B product. In a domestic environment, this product
may cause radio interference, in which case the user may be required
to take adequate measures.

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-1008P, 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 to 15.4 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 required power 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-1008P Fast
Ethernet PoE 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.

Power over Ethernet (PoE)
Power over Ethernet (PoE) integrates power and data onto one single
cabling infrastructure, eliminating the need to have AC power
available at all locations.
Power and Data is integrated onto the same cable, supporting category
5/5e up to 100 Meters. PoE will provide power to PoE compatible
devices, such as IP telephones, wireless LAN access points and IP
security cameras.
PoE is already widely adopted in the market, saving up to 50% of
overall installation costs by eliminating the need to install separate
electrical wiring and power outlets.

UNPACKING AND INSTALLATION
This chapter provides unpacking and installation information for the
Switch.
Unpacking
Open the shipping cartons of the Switch and carefully unpack its
contents. The carton should contain the following items:
One DES-1008P
One AC power adapter
Four rubber feet
CD-ROM with Product Document
Quick Installation Guide.
If any item is found missing or damaged, please contact your local
reseller for replacement.
Installation
The setup of the Switch can be performed using the following steps:
The surface must support at least 1.5 Kg (3.5 lbs) for the Switch.
The power outlet should be within 1.82 meters (6 feet) of the
Switch.
Visually inspect the DC power jack and make sure that it is fully
secured to the power adapter.
Make sure that there is proper heat dissipation from and
adequate ventilation around the Switch. Do not place heavy
objects on the Switch.

Connecting Network Cable
The Switch support 8 10/100Mbps Ethernet ports and Port 1 ~ port 4
are PoE Enabled ports, these PoE port will automatically activate
when a compatible terminal is identified. The Switch will supply
power through the Ethernet port to the connected PoE powered device
(PD).
For legacy devices that are not compatible, the PoE port will not offer
power to this device. This feature allows users to freely and safely mix
legacy and Power over LAN compatible devices on their network.
The Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet and
it runs both in half and full duplex mode using two pair of Category 5
cable.
These RJ45 ports are Auto-MDI type port. The Switch can auto
negotiate to MDI-II or MDI-X type, so you can connect any RJ-45
cable regardless if it is a standard or crossover cable.
