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 –...
D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch General Precautions for Rack- Mountable 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.

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.
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.
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. •...
NIC’s are able to perform 10 times the number of operations in the same amount of time. 802.1P and QoS The DGS-1024D and DGS-1016D Switches support 802.1p priority queuing Quality of Service. The implementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing are described here.
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.

• 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 trans- mitted first.
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-1016D • 24 Auto-Negotiating 10/100/1000Mbps ports on the DGS-1024D Front Panel View of the Switch LED Indicators...
3 seconds. If a cable fault is detected, the corresponding port’s speed LED will light amber for 5 seconds. The Switch is then reset for normal operation. It takes about 2 seconds for the Switch to reset. The entire Cable Diagnostic process takes about 10 seconds from the time the Switch is powered on.

Link/Act 100Mbps/1000Mbps Cable Diagnostic (during boot up only) Description This lights green while the Switch is receiving power. 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.
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.

• Make sure that there is adequate space for proper heat dissipation from and adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front and rear of the Switch for ventilation. • Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges.
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...
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.
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.
(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.
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 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.
