D-Link DGS-1008D 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. Observe and follow service markings.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch • When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe the following guidelines: – Install the power supply before connecting the power cable to the power supply. – Unplug the power cable before removing the power supply. – If the system has multiple sources of power, disconnect power from the system by unplugging all power cables from the power supplies.
D-Link DGS-1008D 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.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch SECTION 1 Introduction Ethernet Technology 802.1P and QOS D-Link Green Ethernet Technology Switch Description Features Ports Front-Panel Components Ethernet Technology Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks.
D-Link DGS-1008D Unmanaged Gigabit Ethernet 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 user is required to instruct the Switch to examine the header of a packet to see if it has the proper identifying tag tagged. Then the user may forward these tagged packets to designated queues on the Switch where they will be emptied, based on priority.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards. For Fast Ethernet or Gigabit Ethernet networks, a Switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch LED Indicators The LED indicators of the Switch include Power, 100/1000Mbps, and Link/Act. The following shows the LED indicators for the Switch along with an explanation of each indicator. Figure 1-2. LED Indicators Comprehensive LED indicators display the conditions of the Switch and status of the network. A description of these LED indicators follows (see LED Indicators). The LED indicators of the Switch include Power, Link/Act, 1000Mbps, and 100Mbps.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch Rear Panel Description DC Power Jack: Power is supplied through an external AC power adapter. Check the technical specification section for information about the AC power input voltage. (For the exact spec. of power adapter, please refer to the package you have bought.) Figure 1-3.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch 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.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch Mounting the Switch on a Wall The DGS-1008D can be mounted on a wall. Two mounting slots are provided on the bottom of the Switch for this purpose. Make sure that the front panel is exposed in order to view the LEDs. Refer to the illustration below: A.) Cement wall 1. Mount the nylon screw anchors into a cement wall. 2. 3. Drive the T3 x 15L screws into the nylon screw anchors. Hook the mounting holes at the back of the switch onto the screws.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch Power On Plug one end of the AC to DC power converter into the power connector of the Switch and the other end into the local power source outlet. After the Switch is powered on, the LED indicators will momentarily blink. This blinking of the LED indicators represents a reset of the system. Power Failure As a precaution, in the event of a power failure, unplug the Switch. When power is resumed, plug the Switch back in.
D-Link DGS-1008D Unmanaged Gigabit Ethernet Switch Section 3 Connecting The Switch Switch To End Node Switch To Hub or Switch Connecting To a Server NOTE: All 8 high-performance NWay Ethernet ports can support both MDI-II and MDI-X connections. 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 most routers. An end node can be connected to the Switch via a twisted-pair Category 3, 4, 5, or 5e UTP/STP cable.
