Conventions For simplicity, the term ‘switch’ refers to all Dual-speed, Ethernet or Fast Ethernet switches, including the DES-1008D. The model number is used only to explain features specific to the DES-1008D switch. Overview of this User’s Guide ♦ Chapter 1, Introduction.

LED indicators of the switch. ♦ Chapter 4, Connecting the Switch. Tells how you can connect the DES-1008D to your Ethernet/Fast Ethernet network. ♦ Appendix A, Technical Specifications. Lists the technical (general, physical and environmental, and performance) specifications of the switch.
10/100 Dual-Speed Switch User’s Guide NTRODUCTION This section describes the features of the DES-1008D, and gives some background information about Ethernet/Fast Ethernet switching technology. Dual-Speed Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for higher performance networks.
Page 12
Your DES-1008D has 8 ports, all of which are dual-speed, capable of full/half duplex operation and NWay enabled. All Ethernet and Fast Ethernet devices connected to the switch will be able to intercommunicate.
10/100 Dual-Speed Switch User’s Guide Switching Technology Switches can increase network performance by: • Eliminating network bottlenecks. • Increasing data throughput (also called aggregate bandwidth) to support more traffic. • Providing high-speed, dedicated (collision-free) data paths for network backbones and servers. •...
10/100 Dual-Speed Switch User’s Guide Eliminating Network Bottlenecks Collisions are a normal occurrence when using Ethernet and they don’t usually have a noticeable affect on overall network performance. However, when too many stations are competing for use of the network, collision rates can become very high and network performance can be affected.
10/100 Dual-Speed Switch User’s Guide Increasing Network Bandwidth A switch is capable of receiving and forwarding transmissions for more than one port at the same time. In the case of half-duplex ports which can either send or receive data, the switch can handle transmissions from up to half of its ports (since the other half are presumably receiving).
10/100 Dual-Speed Switch User’s Guide Since bottlenecks most commonly occur in the backbone and servers, installing a switch to service these areas can greatly increase the speed of a network without having to replace other network components such as the servers themselves, hubs, client NIC’s, etc.
This conversion feature inherent in dual-speed switches allows for gradual migrations to Fast Ethernet allowing older Ethernet stations to communicate with newer Fast Ethernet devices and vice-versa. DES-1008D Dual-Speed Switch Performance Features ♦ Eight UTP/STP ports. All ports are 10/100 Mbps dual-speed, NWay enabled Full/Half duplex.

10/100 Dual-Speed Switch User’s Guide Setup The site where you install the DES-1008D 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 2 kg of weight.

10/100 Dual-Speed Switch User’s Guide ♦ Select a site that is free of obstructions from other equipment or devices. Consider the following points for site selection: ◊ The Switch should be placed high enough where LED indicators can be observed and cable and power connections can be made.
Figure 2.2 Wall Mounting the DES-1008D Switch Power on The DES-1008D Switch comes with a AC/DC power converter for sources of 90 - 230 VAC, 50 - 60 Hz. To turn the switch on, plug one end of the power adapter cord into the DC power connector of the switch and the other end into the local power source outlet.
10/100 Dual-Speed Switch User’s Guide ♦ All of the LED indicators will blink momentarily. This blinking of the LED indicators represents a reset of the system. ♦ The power LED indicator will remain ON. Power Failure As a precaution, the switch should be turned OFF in case of a foreseeable power failure.
The front panel consists of the LED indicators of the switch: Power, 100M, Link/Act and FDX. The LED indicators are used to facilitate monitoring and troubleshooting. DES-1008D Power Figure 3.1 Front panel view of the DES-1008D Switch Identifying External Components...
10/100 Dual-Speed Switch User’s Guide Rear and Side Panels The rear panel of the DES-1008D consists an DC power connector, 8 (10/100 Mbps MDI-X) ports, and 1 Uplink (MDI-II) port (shared with port 1x). A description of the ports appear in the Introduction of this User’s Guide (see Features, Chapter 1).
100M (Green when the respective port is operating at 100Mbps) Link/Act (Green when linked, blinks green when active) Figure 3.4 The DES-1008D Switch LED indicators ♦ Power This indicator lights green when the switch is receiving power; otherwise, it is OFF. If this indicator is not lit, check the DC power connector and wall jack to ensure proper insertion of the power cord.

10/100 Dual-Speed Switch User’s Guide ONNECTING WITCH This chapter describes how to connect the DES-1008D switch to your Ethernet/Fast Ethernet network. Cables • The EIA/TIA 568 Wiring Standard imposes a 100 meter limit on horizontal runs of twisted-pair cables; in this case, from the switch to any other device.
10/100 Dual-Speed Switch User’s Guide blocks do not meet this standard, an upgrade is necessary. We recommend using Category 5 cabling for all connections in order to make it easier to transition all stations to 100 Mbps. Different connection schemes require different types of cable. Please use the following chart when choosing cables: DEVICE PORT...

Hub to Switch One or more 10BASE-T, 10/100 dual-speed or 100Base-TX hubs can be connected to the DES-1008D Dual-speed Switch via a two- pair Category 3, 4, 5 UTP/STP straight cable (the same used to connect a computer). In the case of a 10 Mbps Ethernet hub, a Category 3, 4 or 5 UTP/STP cable can be used;...
10/100 Dual-Speed Switch User’s Guide ports (labeled 1x - 8x) on the switch can be used. Alternatively, a straight cable can be used to connect the Uplink (MDI-II) port on the switch to any one of the non-Uplink (MDI-X) twisted-pair ports on the hub.
(routers, bridges, etc.) via a two-pair Category 3, 4, 5 UTP/STP straight or crossover cable. When connecting the DES-1008D to a 10 Mbps (only) Ethernet device, a Category 3, 4 or 5 UTP/STP cable can be used; a connection to a 10/100 dual-speed or 100 Mbps Fast Ethernet device needs to use Category 5 or better UTP/STP.
Using a straight cable The connection shown above uses a normal straight-through cable to connect the Uplink (MDI-II) port on the DES-1008D switch to one of the non-Uplink (MDI-X) twisted-pair ports on the other switch. Alternatively, a straight cable can be used to connect one of the switch’s normal twisted-pair (MDI-X) ports to another device’s...
