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):

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. The Switch ports can be used to network computers, printers,

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. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a

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. In order to implement QoS, the us

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. For ports operating at 10 or 100Mbps, the L
