If you are not sure of the type of power source required, consult your service provider or local power company. 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. ­ 230 V/50 Hz in most of Europe, the Middle East, and the Far East. ii D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch · Also be sure that attached devices are electrically rated to operate with the power available in your location. Safety Instructions (continued) Use only approved power cable(s). If you have not been provided with a power cable for your system or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The power cable must be rated for the product and for the voltage and current marked on the product's electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product. · To help prevent an electric shock, plug the system and peripheral power cables into properly grounded electrical outlets. These cables are equipped with threeprong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3wire cable with properly grounded plugs. · Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or power strip. · To help protect your system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS). · Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over. Be sure that nothing rests on any cables. · Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local/national wiring rules. · 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. · Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid sudden stops and uneven surfaces. · 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. iii D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware. CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack. After installing system/components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and may result in serious injury. · Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack. iv 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. After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack. Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating. Ensure that proper airflow is provided to components in the rack. Do not step on or stand on any component when servicing other components in a rack. NOTE: A qualified electrician must perform all connections to DC power and to safety grounds. All electrical wiring must comply with applicable local or national codes and practices. CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. CAUTION: The system chassis must be positively grounded to the rack cabinet frame. Do not attempt to connect power to the system until grounding cables are connected. Completed power and safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard will exist if the safety ground cable is omitted or disconnected. 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. v D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch You can also take the following steps to prevent damage from electrostatic discharge (ESD): 1. When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body. When transporting a sensitive component, first place it in an antistatic container or packaging. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads, and an antistatic grounding strap. 2. 3. vi D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch SECTION 1 Introduction 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. A number of high-speed LAN technologies are proposed to provide greater bandwidth and improve client/server response times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive, smooth evolution from 10BASE-T technology. 100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet protocol. 1 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch 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 100Mbps Fast Ethernet and a one hundredfold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company's existing investment in hardware, software, and trained personnel. The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your sub-networks. Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NICs are able to perform 10 times the number of operations in the same amount of time. In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today's and tomorrow's rapidly improving switching and routing internetworking technologies. 2 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Switching Technology Another key development pushing the limits of Ethernet technology is in the field of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by making it possible for a local area network to be divided into different segments that do not compete with each other for network transmission capacity, decreasing the load on each segment. The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another (from one port to another) is automatically forwarded by the switch, without interfering with any other 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." A switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and new 100Mbps networks. 3 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router and the setup and maintenance required make routers relatively impractical. Today's switches are an ideal solution to most kinds of local area network congestion problems. Switch Description The DGS-1016D/DGS-1024D Switch is equipped with 16 or 24 ports providing dedicated 10, 100, or 1000 Mbps bandwidth. These ports can be used for connecting PCs, printers, servers, routers, Switches, and other network devices. The 16/24 multi-speed ports use standard twisted pair cabling and are ideal for segmenting networks into small, connected subnets. Each port can support up to 2000 Mbps of throughput in full-duplex mode. This stand-alone Switch enables the network to use some of the most demanding multimedia and imaging applications concurrently with other user applications without creating bottlenecks. Features The DGS-1016D/DGS-1024D 16/24-Port 10/100/1000BASE-T Gigabit Ethernet Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. · · · Sixteen (16) or twenty-four (24) 10/100/1000BASE-T Gigabit Ethernet ports Cable Diagnostic function at Switch boot up Supports Auto-Negotiation for 10/100/1000Mbps and duplex mode 4 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch · · · · · · · · · · Supports Auto-MDI/MDIX for each port Support Full/Half-duplex transfer mode for 10 and 100Mbps Support Full-duplex transfer mode for 1000Mbps Full wire speed reception and transmission Store-and-Forward Switching method Supports 8K absolute MAC addresses Supports 512 Kbyte RAM for data buffering Extensive front-panel diagnostic LEDs IEEE 802.3x flow control for Full-duplex Back pressure flow control for Half-duplex 5 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Note: For illustration purposes, the DGS-1016D is used. Front-Panel Components The front panel of the Switch consists of LED indicators, 16 or 24 (10/100/1000 Mbps) Ethernet ports. Figure 1-1. Front Panel View of the Switch Comprehensive LED indicators display the status of the Switch and the network. 10/100/1000BASE-T Ports: Sixteen (16) or twenty-four (24) Gigabit Ethernet, AutoNegotiating ports (10/100/1000Mbps) Comprehensive LED indicators display the conditions of the Switch and status of the network. 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. 6 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Figure 1-2. LED Indicators 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. The Cable Diagnostic functions of the Switch are indicated by a combination of the Speed and the Link/Act LEDs, as described below. Power Indicator This green indicator illuminates when the Switch is receiving power. Link / Act This green indicator illuminates steadily when a port is connected to a station successfully and has a good link. The indicator will blink to indicate that a port is transmitting or receiving data on the network. Speed -- 100Mbps/amber; 1000Mbps/green; 10Mbps/off This indicator is green when the port is connected to a 1000Mbps Ethernet station. It is unlit when the port is connected to a 10Mbps Ethernet station or 100Mbps Fast Ethernet station. Cable Diagnostic - LED Indications When the Switch is first powered on, the Cable Diagnostic function is initialized and run. The Cable Diagnostic function will detect three common faults in an Ethernet cable connecting the Switch to a remote network device: an open circuit (a lack of continuity between the pins at each end of the Ethernet cable or a disconnected cable), a short circuit (two or more conductors short7 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch circuited), and the checking of connectivity for each of the eight wires of a cable to ensure its capability for running 1000Mpbs. Any of these common cable faults will be detected by the Cable Diagnostic function and the LEDs will display the results of the Cable Diagnostic function as follows: Open, Short, or Improper Connectivity - Speed LED: Amber - Link/Act LED: Off Cable connection good - Speed LED: Green - Link/Act LED: Off The Cable Diagnostic function operates only during the Switch boot up (when the Switch is first powered on). The Cable Diagnostic first scans the 16 or 24 Ethernet ports to determine if the Ethernet cable is in good working order. This process is indicated by the Speed LED blinking green for each of the 16 or 24 ports, sequentially. The initial port scan takes about 3 seconds. If a cable fault is detected, it is indicated by the corresponding port's Speed LED glowing amber for 5 seconds, after the initial port scan. 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 booted. So, from the time power is first applied to the Switch, about 10 seconds is required before the Switch will begin normal operation. Note: There is no display of cable faults detected by the Cable Diagnostic function during the normal operation of the Switch, only when the Switch is booted up or power-cycled. NOTE: The Cable Diagnostic function does not support 10M/100M. If the port is connected to a 10M/100M device, see the Link LED to check if the cable is good or not. 8 D-Link DGS-1016D/DGS-1024D Unmanaged Gigabit Ethernet Switch Rear Panel Description Power Input: Internal universal power supply (100-240VAC; 12V/2A, 5V/3A).
