D-Link DGS-1016T/DGS-1024T 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.
SECTION 1 Introduction Switch Description Switch Features D-Link Green Ethernet Technology Ports Front-Panel Components LED Indi cators Power Input on Rear Panel Switch Description The 16-port DGS-1016T and 24-port DGS-1024T Switches provide dedicated 10, 100 or 1000 Mbps Ethernet bandwidth on each port. The ports will automatically detect the speed, duplex and MDI/M DIX status of the device it is connecting to, and adjust these settings accordingly.
• Sixteen (DGS-1016T) or twenty-four (DGS-1024T) 10/ 100/1000Mbps Ethernet ports • Cable d iagnostics function at Switch boot up • D-Link Green Ethernet Technology • Auto-Negotiation for 10/100/ 1000Mbps and duplex mode • Auto-MDI/MDI-X for each port • Supports Full/ Half-duplex transfer mode for 10 and 100Mbps •...
Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for C SMA/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.
802.1P and QoS The DGS-1024T and DGS-1016T Switches support 802.1p priority queuing Quality of Service. The imp lementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing are described here. Advantages of QoS QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet Protocol), web browsing applications, file server applications or video...
The Switch uses strict priority for Scheduling. Strict priority-based scheduling, any packets residing in the higher priority queues are transmitted first. D-Link Green Ethernet Technology D-Link Green Ethernet imp lements special power-saving features under speed at 1000Mbps that detect cable length and link status and adjust power usage accordingly.
Method 2: D-Lin k Green Ethernet detects the length of connected Ethernet cable and adjusts power usage accordingly without affecting performance. This way, a port connected to a 10m cable only uses as much power as it needs, instead of using full power, wh ich is only needed for 100m cables.
Front-Panel Components Note: The Switch illustrations used for this manual depict only the model DGS-1016T Switch. On the front panel of the Switch you will see the following. • LED status indicators • 16 Auto-Negotiating 10/ 100/ 1000Mbps ports on the DGS-1016T •...
Cable Diagnostics Upon booting up the Switch, a Cable Diagnostics is used to detect two 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 indicat es 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...
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 (100-240VA C : 12V/ 3.3A). The AC power connector is a standard three -pronged connector that supports the power cord.
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. The carton should contain the follo wing items: • One DGS-1016T 16-Port/DGS-1024T 24-Port 10/ 100/1000BASE-T Gigab it Ethernet Switch •...
Before You Connect to the Network The site where you install the Switch may great ly 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.
Mounting the Switch on a Rack The DGS-1016T/1024T 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 Attach the ears to each side of the Switch, using the screw-holes located on the side of the device.
