D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Safety Instructions Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage. Throughout this safety section, the caution icon ( ) is used to indicate cautions and precautions that you need to review and follow. Safety Cautions To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions.
D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Safety Instructions (continued) • To help avoid damaging your system, be sure the voltage selection Switch (if provided) on the power supply is set to match the power available at your location: – 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea and Taiwan – 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan.
D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch General Precautions for RackMountable Products • • Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the system and the rack for specific caution statements and procedures. Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware.
D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Safety Instructions (continued) • • • • • • • Always load the rack from the bottom up, and load the heaviest item in the rack first. Make sure that the rack is level and stable before extending a component from the rack. Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can pinch your fingers.
D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Protecting Against Electrostatic Discharge Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of the electronic components, such as the microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis. You can also take the following steps to prevent damage from electrostatic discharge (ESD): 1.
SECTION 1 Introduction Switch Description Switch Features Ports Front-Panel Components LED Indicators Power Input on Rear Panel Switch Description The 16-port DGS-1016D and 24-port DGS-1024D Switches provide dedicated 10, 100 or 1000 Mbps Ethernet bandwidth on each port. The ports will automatically detect the speed, duplex and MDI/MDIX status of the device it is connecting to, and adjust these settings accordingly.
Switch Features The DGS-1016D 16-Port and DGS-1024D 24-port Switches do not require any management. Both Switches are designed for easy installation, flexibility and high performance. Connect devices to the Switch as the scale and volume of network traffic increases.
Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet.
which packets from various applications are mapped to and assigned a priority. The illustration below shows how 802.1P priority queuing is implemented on the Switch. The eight IEEE 802.1P priority levels defined by the standard are mapped to the four class queues used in the Switch. Mapping QoS on the Switch The picture above shows the default priority setting for the Switch. Class-3 has the highest priority of the four priority queues on the Switch.
• Priority 7 is assigned to the Switch's Q3 queue. The Switch uses strict priority for Scheduling. Strict priority-based scheduling, any packets residing in the higher priority queues are transmitted first.
Front-Panel Components Note: The Switch illustrations used for this manual depict only the model DGS-1016D Switch. On the front panel of the Switch you will see the following.
Cable Diagnostic Upon booting up the Switch, a Cable Diagnostic is used to detect three problems that may prevent successful connection. This feature operates only on ports that are connected to 1000Mbps devices. If there are problems on a port connected to a Gigabit Ethernet device (1000Mbps), try restarting the Switch and watch the speed (100/1000Mbps) LED indicators to determine is the problem is a fault in the cable or connecting hardware.
LED Indicator Description Power This lights green while the Switch is receiving power. Link/Act A steady green light indicates the corresponding port is connected and a valid link is established. This will blink green when there is activity on the port. 100Mbps/1000Mbps The speed indicator will light green if the corresponding port is connected and operating at 1000Mbps. An amber light indicates the port is operating at 100Mbps.
Power Input on Rear Panel The power cable connection is located on the rear panel of the Switch. Rear panel view of the Switch Switch power input is provided by and internal universal power supply (100-240VAC : 12V/3.3A). The AC power connector is a standard three-pronged connector that supports the power cord. Please see the Power On section below for instructions on how to properly connect the Switch to a power source.
SECTION 2 Installation Package Contents Before You Connect to the Network Installing the Switch Power On Package Contents Open the shipping carton of the Switch and carefully unpack its contents.
Before You Connect to the Network The site where you install the Switch may greatly affect its performance. Please follow these guidelines for setting up the Switch. • Install the Switch on a sturdy, level surface that can support at least 3 kg (6.6 lbs) of weight. Do not place heavy objects on the Switch. • The power outlet should be within 1.82 meters (6 feet) of the Switch. • Visually inspect the power cord and see that it is fully secured to the AC power port.
Mounting the Switch on a Rack The DGS-1016D/1024D can easily be mounted on a rack. Two mounting ears are provided for this purpose. Make sure that the front panel is exposed in order to view the LEDs. Please refer to the following illustrations: Mounting the Switch to a Rack 1. 2. Attach the ears to each side of the Switch, using the screw-holes located on the side of the device. Firmly attach the ears to the rack as shown.
Attaching the Rubber Feet Use rubber feet provided. Position and apply rubber feet to the underside of the DGS-1016D/1024D Switch. Attaching the Rubber Feet Provide for Adequate Ventilation CAUTION: Do not place any device on top of Switch, or place the Switch on top of any device or object that will block the free flow of air through the ventilation slots on the sides, top, and bottom of the Switch’s case.
Power On To power on the Switch, Plug-in the female connector of the provided power cord into this socket, and the male side of the cord into a suitable power source. After the Switch is powered on, the LED indicators will blink briefly while the system resets. Power Failure As a precaution, in the event of a power failure, unplug the Switch. When power is resumed, plug the Switch back in.
Section 3 Connecting the Switch Switch to End Node Switch to Hub or Switch Connecting to a Server NOTE: All Ethernet ports auto-detect MDI-II/MDI-X, port speed (10, 100, 1000Mbps) and duplex of the device connected to the Switch. Cable Quality For all connections to the Switch, use these rules to determine the • For connections to 10BASE-T and 100BASE-TX devices, use Category 5 or 5e UTP/STP cable. • For connections to 1000BASE-T and 100BASE-TX devices, use Category 5e or better UTP/STP cable.
Switch to End Node End nodes include PCs outfitted with a 10, 100 or 1000 Mbps RJ-45 Ethernet/Fast Ethernet Network Interface Card (NIC) and Ethernet ready routers. Use standard Ethernet cable to connect the Switch to end nodes. Switch ports will automatically adjust to the hardware characteristics (MDI-II/MDI-X, speed, duplex) of the device to which it is connected. Switch connected to an end node Observe the guidelines for cable quality stated at the beginning of this section.
Switch to Hub or Switch Connect to another switch or hub Observe the guidelines for cable quality stated at the beginning of this section. The Link/Act LEDs for each port lights green when the link is valid.
Connecting to Network Backbone or Server Any port may be used to uplink the Switch to a network backbone or network server. When linking to a 10000BASE-T device the port operates in full duplex mode. Connection to a Server Observe the guidelines for cable quality stated at the beginning of this section. The Link/Act LEDs for each port lights green when the link is valid.
