Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage. To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions. Observe and follow service markings. Do not service any product except as explained in your system documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to an electrical shock.
• 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. • Also be sure that attached devices are electrically rated to operate with the power available in your location.
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.
D-Link DES-1008E 8-port Desktop Switch Wall Mount Kit Power Adapter The setup of the DES-1008E can be performed using the following steps: • The power outlet should be within 1.82 meters (6 feet) of the Switch. • Visually inspect the DC power jack and make sure that it is fully secured to the power adapter. • Do not cover the ventilation holes on the sides of the Switch, and make sure there is adequate ventilation around it. • Do not place heavy objects on the switch. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. 100BASE-TX (Fast Ethernet) provides a cost-effective and high-performance solution for small workgroups, SMBs (Small to Medium...
When two switching nodes are communicating, they are connected with a dedicated channel between them, so there is no contention for network bandwidth with other nodes. As a result, the switch reduces considerably, the likelihood of traffic congestion.
• The DES-1008E is scalable, allowing two or more DES-1008E switches to be cascaded together. Since all ports support 200Mbps, any one of its eight ports may be used to cascade to an additional switch to open a Full-Duplex Fast Ethernet pipe. • The DES-1008E is the perfect choice for a department or office planning to upgrade to Fast Ethernet. The DES-1008E can accommodate 10Mbps or 100Mbps devices, providing a flexible solution for existing (10Mbps) Ethernet workgroups.
Hardware Overview Top Panel (LEDs) Power Indicator This green indicator light is on when the DES-1008E is receiving power; otherwise, it is off. Link/Act This LED indicator light is green when the port is connected to an Ethernet device and will blink as Ethernet data is transmitted or received.
Power is supplied through an external power adapter. Check the technical specification section for information about the power input voltage. Since the DES-1008E does not require a power button, plugging its power adapter into a power outlet will immediately power it on.
This section will explain how to connect Ethernet devices to your new D-Link switch and how to mount the switch. Before You Connect to the Network The site where you install the Switch may greatly 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. Do not place heavy objects on the Switch. • The power outlet should be within 1.82 meters (6 feet) of the Switch. • Visually inspect the power cord and see that it is fully secured to the AC power port. • 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.
Mounting the Switch on the Wall The DES-1008E can also be mounted on a wall. Two mounting slots are provided on the bottom of the switch for this purpose. Please make sure that the front panel is exposed in order to view the LEDs. Please refer to the illustration below: 1.
Hub/Switch to DES-1008E A hub (10 or 100BASE-TX) can be connected to the DES-1008E via a two-pair Category 3, 4, or 5 UTP/STP Straight-Through or Crossover cable. For 100Mbps operation a Category 5 cable must be used. The connection is accomplished from any port of the hub to any port of the DES-1008E.
The DES-1008E has Auto-MDI ports which automatically sense the type of cable being used (e.g. Crossover or Straight-through) and adjust themselves accordingly to pass data over the network. 3. What is the maximum length of Category 3, 4 or 5 twisted pair cable that can be used between the DES-1008E and other devices such as routers, switches, computers, etc.? The maximum length of Category 3, 4 or 5 twisted pair cable that can be used between computers and other devices on a network is 100 meters or about 328 feet. Keep in mind that this is a theoretical limit. Usually, you will want to keep the distance between devices well below...
Check your IP address After you install your new D-Link adapter or if you already have an Ethernet adapter installed on your computer, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. router) automatically. To verify your IP address, please follow the steps below.
Statically Assign an IP address If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below: Step 1 Windows® 7 - Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Change Adapter Setting. Windows Vista®...
A port that does not learn device addresses, and that receives all frames with an unknown address. Backbone ports are normally used to connect the Switch to the backbone of your network. Note that backbone ports were formerly known as designated downlink ports.
Console Port The port on the Switch accepting a terminal or modem connector. It changes the parallel arrangement of data within computers to the serial form used on data transmission links. This port is most often used for dedicated local management.
100Mbps technology based on the Ethernet/CD network access method. Flow Control – (IEEE 802.3x) A means of holding packets back at the transmit port of the connected end station. Prevents packet loss at a congested switch port. Forwarding The process of sending a packet toward its destination by an internetworking device.
Standard 8-wire connectors for IEEE 802.3 10BASE-T networks. RMON Remote Monitoring. Subset of SNMP MIB II, which allows monitoring and management capabilities by addressing up to ten different groups of information. Redundant Power System. A device that provides a backup source of power when connected to the Switch. Server Farm A cluster of servers in a centralized location serving a large user population. SLIP Serial Line Internet Protocol.
The port in a resilient link that will take over data transmission if the main port in the link fails. Switch A device that filters, forwards, and floods packets based on the packet’s destination address. The Switch learns the addresses associated with each switch port and builds tables based on this information to be used for the switching decision.
