1 Product Introduction
The DGS-1008P Switch provides 8 Gigabit Ethernet ports, of which 4 ports supporting Power over Ethernet
(PoE) for PoE applications such as wireless Access Points (APs), IP cameras, and IP phones, and the other
4 ports without PoE for computers, printers and Network Attached Storage (NAS) onto a network. With
wirespeed Gigabit capacity, DGS-1008P provides non-blocking switching for both home and office
environment.
IEEE 802.3af Power over Ethernet
The first 4 ports of the DGS-1008P support the IEEE 802.3af PoE protocol. Each of the 4 ports can supply
48V, up to 15.4 watts power to the IEEE 802.3af-compliant Powered Device (PD) directly. It minimizes the
clutter of extra cables making the network deployment more easily especially when device are far from
power outlets.
Easy to Use, Safe and Excellent Performance
DGS-1008P is a Plug-and-Play device that requires no configuration. It supports auto-MDI/MDI-X on all ports,
and eliminates the need of crossover cables for connection to another switches or hubs. Auto-Negotiation on
each port senses the link speed (either 10, 100 or 1000M) of a network device and intelligently adjusts the
compatibility and optimal performance. Fanless design extends the product life time and also reduces the
noise when operating. DGS-1008P also features diagnostic LEDs, which display the status and activity,
allowing you to quickly detect and correct problems on the device.
DGS-1008P features many safety functions to prevent the unexpected overloading of the PoE power. The
Switch will cut off the power feed immediately when any error is detected, protecting both the PoE device
and the Switch from damage.
The Gigabit PoE ports provide a larger bandwidth for high speed network applications, especially
IEEE802.11n AP, high resolution video cameras, and phones. Combining the convenience of PoE, superior
performance, and ease of use, DGS-1008P is the ideal PoE solution for both home and small business
networks.
Product Outlook
Front Panel
Figure 1 – DGS-1008P Front Panel
Power: The Power LED lights up when the Switch is connected to a power source.
PoE Max: The PoE Max LED lights up in red when the total PoE output of the Switch is over 45 watts. In the
mean time, no additional PoE device can be supported. When the user unplugs a Powered Device (PD) from
the DGS-1008P and lowering the total PoE output less than 45 watts, the PoE Max LED will keep blinking for
2 minutes. In the mean time, an additional PD is possible to be supported.
Port PoE LED (1-4): When the Port PoE LED glows green, it indicates that the port is feeding power to the
PD. When the Port PoE LED glows red, it indicates that the power feeding failed, possibly because:
PoE total power budget shortage.
Over current: Over the power current of PD’s classification.
Short circuit: When PD is performing as “Short Circuit”, causing short current.

Port Link/Act/Speed LED (1-8): The Port LED indicates the link status of corresponding ports. Blinking
indicates that the Switch is either sending or receiving data to the port. When the port LED glows in amber, it
indicates that the port is running on 10M or 100M. When the port LED glows in green, it is running on
1000Mbps.

3 Understanding The Switch Features
Cable Diagnostics
DGS-1008P will scan all ports when device booting up. The diagnosis results will be displayed by port LED
at the first 1 second after port scan finished. And following are the explanation of the result:
Solid Green: A Gigabit connection is detected and the cable is good.
Solid Amber: No connection, bad cable or 10/100M connection is detected.
The quality of cables will impact the diagnosis results. A Gigabit connection may lower to 10/100M due to
wrong or bad quality Ethernet cables. Twisted pair Cat 5, 5e or better cable is required for Gigabit Ethernet.
PoE Rule
DGS-1008P supports many PoE features to guarantee the safety and stability of PoE power supply.
PoE Power Budget: DGS-1008P has set a limitation of maximum PoE power supply at 52 Watts to protect
the Switch and to stabilize the power transmitting to the PoE devices.
Priority: DGS-1008P has pre-defined the PoE priority for PoE ports to prevent unexpected overloading
situation from happening. Lower port numbers have higher priorities for power feeding. (Port 1 > Port 2 >
Port 3 > Port 4). When PoE overload is detected, the power supply of higher port numbers will be cut off first.
Guard Band: DGS-1008P has reserved a 7 watts Guard Band to prevent the power supply from exceeding
the PoE Power Budget. When the Switch detects the current PoE output has reached 45 watts, the Power
Max LED will light up and the Switch will check the priority of each PoE port. In the mean time, if a new PoE
device is connected, the Switch will cut off the power of the port with higher port number.
For example: When Port 2~4 are all feeding 15.4 watts power to the clients (total PoE power used = 46.2
watts), and a new PoE device is connected to port 1, the power of port 4 will be cut off.
QoS
DGS-1008P supports 4 levels of transmission queue that guarantees the important traffic will always be
transmitted first. The Switch will check the priority tags in the packets and map them into corresponding
queue levels. Below are the mapping rules:
For DSCP tag:
DSCP value 0-15 map to Queue 0 (Lowest priority queue)
DSCP value 16-31 map to Queue 1
DSCP value 32-47 map to Queue 2
DSCP value 48-63 map to Queue 3 (Highest priority queue)
For 802.1p tag:
Priority value 1 and 2 map to Queue 0 (Lowest priority queue)
No 802.1p tag or priority value 3 map to Queue 1
Priority value 4 and 5 map to Queue 2
Priority value 6 and 7 map to Queue 3 (Highest priority queue)
If a packet has both DSCP and 802.1p tags, the DSCP tag will be mapped.
Power Saving
DGS-1008P supports 2 power saving modes of Ethernet ports. The switch ports will auto detect the status of
the link and activate the power saving function automatically.

Power Saving by Link Status: Drastically save power when the switch port link is down. For example, when
there are no PC connections or the connected PC is powered off.
Power Saving by Cable Length: Detects the length of connected RJ-45 cables and adjusts power usage
accordingly without affecting performance. When the RJ-45 connection is less than 10m, the switch will
reduce the power output instead of using full power, which is only needed for 100m cables.
