ABOUT THIS GUIDE  
Congratulations on your purchase of the D-Link DES-1005P. This  
device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet  
network capabilities in a highly flexible package. Port-1 on the switch  
supports 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 manual will familiarize you with the DES-1005P and guide you  
through the installation process.

INTRODUCTION  
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  
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  
Unpacking  
Open the box and carefully unpack it. The box should contain the  
following items:  
One DES-1005P  
One External Power Adapter  
Wall Mount Kit  
Four rubber feet  
Quick Installation Guide  
If any item is found missing or damaged, please contact your local  
reseller for replacement.  
Setup  
The setup of the DES-1005P can be performed using the following  
steps:  
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.  
Do not cover the ventilation holes on the sides of the Switch,  
and make sure there is adequate ventilation around it.  
Do not place heavy objects on the switch.

Connecting Network Cable  
The Switch support 5 10/100Mbps Ethernet ports and Port 1 PoE  
Enabled port, the 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.

Power LED Indicator:  
This green indicator light is on when the DES-1005P is receiving  
power; otherwise, it is off.  
Ethernet Ports (Port 1~5):  
These ports support network speeds of either 10Mbps or 100Mbps,  
and can operate in half- and full- duplex transfer modes. These  
ports also support automatic MDI/MDIX crossover detection,  
which gives the Switch true, “plug and play” capabilities. Just  
connect any network cable between the Switch and the device,  
and The Switch will automatically detect the settings of the  
device and adjust itself accordingly.  
PoE Port (Port 1 only):  
The PoE port will automatically activate when a compatible  
terminal is identified. The Switch will supply power through the  
Ethernet port to the connected PoE device.  
For legacy devices that are not compatible, the PoE port will not  
offer the power to this device. This feature allows users to freely  
and safely mix legacy and PoE compatible devices on the network.

PoE Rule  
1. Supplies power to PD device, meeting IEEE802.3af standards. It  
is able to provide power to PD devices more sufficiently.  
2. Auto discovery feature, automatically recognize the connection of  
PD device and immediately sends power to it  
3. Active circuit protection, automatically disables the port if there is  
a short while other ports remain active  
4. Auto disable port via two different methods as below:  
a. Over Current Protection  
- 802.3af mode: if the current is over 375mA while other ports  
remain active, the port will be auto disabled.  
b. Over Output Power Limit  
- 802.3af mode: if the port is over 15.4W while other ports  
remain active, the lower priority port will be auto disabled.  
5. DES-1005P should follow the standard PSE pin-out standard of  
Alternative A which is sending out power over number 1,2,3,6  
pins of 8 wires of CAT5 UTP cable  
6. DES-1005P works with all D-Link 802.3af devices DES-1005P  
works with all non-802.3af capable D-Link AP, IP Cam and IP  
phone via DWL-P50
