Product Introduction

The DGS-1008P Switch provides 8 Gigabit Ethernet ports, 4 of which support Power over Ethernet (PoE) for PoE applications such as powering wireless Access Points (APs), IP cameras, and IP phones. The remaining 4 non-PoE ports can be used to connect devices such as computers, printers, and Network Attached Storage (NAS) to the network. With wire-speed Gigabit throughput, the DGS-1008P provides non-blocking switching for both home and office environments.
IEEE 802.3af/at Power over Ethernet
The first four ports of the DGS-1008P support the IEEE 802.3af and IEEE 802.3at PoE protocols. Each of these four ports can directly supply up to 15.4 watts of power to an IEEE 802.3af-compliant Powered Device (PD) or up to 30 watts of power to an IEEE 802.3at-compliant Powered Device (PD). This effectively minimizes the clutter of extra cables and is especially suitable for expanding the network with remote devices that are otherwise too far away from a power outlet.
Easy to Use, Safe, and Excellent Performance
The DGS-1008P is a plug-and-play device that requires no additional configuration after installation. Support for auto-MDI/MDI-X on all ports eliminates the need for crossover cables when connecting to other switches or hubs. Auto-negotiation on each port senses the link speed (either 10, 100, or 1000 Mbps) of a connected network device and intelligently adjusts for improved compatibility and optimal performance. The fanless design of the DGS- 1008P extends the device’s lifetime while also significantly reducing noise when operating. The DGS-1008P also features a set of diagnostic LEDs which display the status and activity of each port on the device, allowing the user to quickly detect and correct problems if they occur.
The DGS-1008P features several safety functions to prevent an unexpected overload of PoE power. In the event of such an overload, the Switch will immediately cut off the power supply to any connected powered device, protecting both the PoE device and the Switch from being damaged.
All ports on the DGS-1008P are Gigabit-capable, providing a larger bandwidth for high-speed network applications, especially IEEE 802.11n access points, high-resolution video cameras, and IP phones. Combining the convenience of PoE, superior performance, and ease of use, the DGS-1008P is the ideal PoE solution for expanding both home and small business networks.

has exceeded the Guard Band threshold of 73 watts but is still below the total budget of 80 watts. For more information on the Guard Band feature, please refer to Understanding the Switch Features.
Blinking red| This indicates the total PoE budget of 80 watts has been exceeded. When the Switch’s PoE budget is being fully utilized, no additional devices can be powered through the Switch. When the user unplugs a Powered Device (PD) from the DGS-1008P, lowering the total PoE output to less than 73 watts, the PoE Max LED will turn off. The remaining available PoE budget can then be used to power another powered device.
Off| The current PoE power consumption is below the 73 watts Guard Band threshold.
PoE| Solid green| The port is providing power to a connected powered device (PD).
Solid red| The PoE power feed from this port has failed as a result of one of the following possible causes:
/ Insufficient total PoE budget.
Overcurrent: The maximum allowed current of the power device was exceeded.
Short circuit: The powered device has short-circuited.
Off| No PoE-powered device is connected to this port

Hardware Installation

This chapter provides installation information for the D-Link DGS-1008P.

Installation Precautions

For safe switch installation and operation, it is recommended to:
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 and adequate ventilation around the switch.
Install the Switch in a site free from strong electromagnetic sources, vibration, dust, and direct sunlight.
Not place heavy objects on the Switch.

Grounding the Switch

This section describes how to connect the Switch to the ground. It is necessary to complete this procedure before powering on the Switch.

Required Tools and Equipment

One ground screw (attached to the back panel).
Ground cable (not included in the accessory kit): The grounding cable should conform to local and national installation requirements. Depending on the power supply and system, a 12 to 6 AWG copper conductor is required for a US installation. Commercially available 6 AWG wire is recommended. The length of the cable depends on the proximity of the Switch to proper grounding facilities.
A screwdriver (not included in the accessory kit).

The following steps explain the procedure for connecting the Switch to a protective ground:

Verify that the system is powered off.
Use the ground cable to place the #8 terminal lug ring on top of the ground screw opening, as seen in the figure below.
Insert the ground screw into the ground screw opening.
Using a screwdriver, tighten the ground screw to secure the ground cable to the Switch.
Attach the terminal lug ring at the other end of the grounding cable to an appropriate grounding stud or bolt on the rack where the Switch is installed.
Verify that the connections from the ground connector on the Switch to the rack are securely attached.

Attaching the Rubber Pads

The DGS-1008P comes with a strip with 4 adhesive rubber pads to place on the bottom of the device to prevent the Switch from damaging the surface it is placed on. This allows the Switch to be placed on virtually any flat surface. To attach the rubber pads, simply remove the rubber pads from the adhesive strip and stick one pad on each corner on the bottom panel of the Switch.

Mounting the Switch on a Wall

The DGS-1008P can also be mounted to a wall for more convenient placement. Please follow the instructions below for more information on how to mount the device to different types of walls.

Mounting the Switch on a hard surface wall (e.g. brick, cement)

Drill two holes that align with the keyholes on the back of the Switch in the wall where you want to mount the DGS-1008P and place the two included nylon screw anchors into the drilled holes.
Drive the two screws included in this package into the placed nylon anchors.
Hook the mounting keyholes on the back of the Switch onto the screws to secure the device to the wall.

Mounting the Switch on a soft surface wall (e.g. wood)

Drive the two screws included in this package in the wooden wall where you want to mount the DGS1008P so that they align with the keyholes on the back of the Switch.
Hook the mounting keyholes on the back of the Switch onto the screws to secure the device to the wall.

Powering on the Switch

After connecting the switch to the network using a compatible network cable such as Cat.4/5/5e, simply connect the Switch to a power outlet to activate the device.

Understanding The Switch’s Features

Power over Ethernet (PoE)

The DGS-1008P supports many PoE features to guarantee the safety and stability of the Switch and the connected powered devices.
PoE Power Budget: The total PoE budget of the DGS-1008P is limited to a maximum of 80 watts to both protect the Switch and to stabilize the power being transmitted to the PoE-powered devices.
PoE Port Priority: The DGS-1008P is configured to have predefined PoE priorities for all PoE ports to prevent events such as unexpected overloading on PoE ports. Lower port numbers have a higher priority for supplying power, for example port 1 > port 2 > port 3 > port 4. When a PoE overload is detected, the power supply from the higher number ports will be cut off first.
Guard Band: The DGS-1008P reserves 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 73 watts, the PoE Max.
LED will light up solid red and the Switch will not supply power to new connected devices.
For example: When Port 3 to 4 are both feeding 30 watts of power to the attached clients (total PoE power used = 60 watts), and a new powered device is connected to port 1 that is being supplied more than 13 watts of power, the Switch will not supply the power to Port 4 device.

Power Saving

The DGS-1008P supports IEEE 802.3az Energy Efficient Ethernet (EEE), which constantly monitors all ports for data transmission and will put inactive ports in sleep mode to save power.
