ABOUT THIS GUIDE

Congratulations on your purchase of the DES-1008D. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible desktop package.

Purpose

The purpose of this manual is to show you how to install and configure your DES-1008D.

INTRODUCTION

This chapter describes the features of the DES-1008D and some background information about Ethernet/Fast Ethernet switching 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 have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. The non-disruptive and smooth evolution nature, and the dominating potential market base, virtually guarantee cost effective and high performance Fast Ethernet solutions in the years to come.
100Mbps Fast Ethernet is a new 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 CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training.

Switching Technology

Another approach to pushing beyond the limits of Ethernet technology is the development 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 dividing a local area network into different segments, which don’t compete with each other for network transmission capacity. The DES-1008D acts as a high-speed selective bridge between the individual segments. The DES-1008D, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards.

For Fast Ethernet networks, a DES-1008D is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.” A DES-1008D can be used to split parts of the network into different collision domains, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. DES-1008Ds supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between the existing 10Mbps networks and the new 100Mbps networks.
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, the setup and maintenance required make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems.

Features

• The DES-1008D was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously.
• The DES-1008D with its small, compact size was specifically designed for small to middle workgroups. The DES-1008D can be installed where space is limited; moreover, the DES-1008D provides immediate access to a rapidly growing network through a wide range of functions.
• The DES-1008D is ideal for deployment with multiple high-speed servers for shared bandwidth 10Mbps or 100Mbps workgroups. With the highest bandwidth 200Mbps (100Mbps full-duplex mode), any port can provide workstations with a congestion-free data pipe for simultaneous access to the server.
• The DES-1008D is expandable by cascading two or more DES-1008Ds together. As all ports support 200Mbps, the DES-1008D can be cascaded from any port and to any number of DES-1008Ds.
• The DES-1008D is a perfect choice for sites planning to upgrade to Fast Ethernet in the future. Ethernet workgroups can connect to the DES-1008D now, and you can change adapters and hubs anytime later without needing to change the DES-1008Ds or reconfigure the network.
• The DES-1008D combines dynamic memory allocation with store-and-forward switching to ensure that the buffer is effectively allocated for each port while controlling the data flow between the transmit and receive nodes to guarantee against all possible packet loss.
• The DES-1008D is a managed 10/100 Fast Ethernet switch that offers solutions in accelerating small Ethernet workgroup bandwidth. Other key features are:
• Uplink/ MDI-II (media dependent interface) port for uplink to another switch, hub or repeater.
• Store and forward switching scheme capability. As the result of complete frame checking and error frame filtering, this scheme prevents error packages from transmitting among segments. ?? NWay Auto-negotiation for any port. This allows for auto- sensing of speed (10/100Mbps) thereby providing you with automatic and flexible solutions in your network connections.
• Flow control for any port. This minimizes dropped packets by sending out collision signals when the port’s receiving buffer is full. Note that flow control is only available in half duplex mode.
• The data forwarding rate per port is at a wire speed of 100Mbps speed.
• The data forwarding rate per port is at a wire speed of 10Mbps speed.
• The data filtering rate eliminates all error packets, runts, etc., per port at a wire speed of 100Mbps speed.
• The data filtering rate eliminates all error packets, runts, etc., per port at a wire speed of 10Mbps speed.
• 8K MAC address entries table per device for the DES-1008D.
• 256 KB RAM buffer per device for the DES-1008D.
• Network looped detecting.

Unpacking and Setup

This chapter provides unpacking and setup information for the DES-1008D.

Unpacking

Open the box and carefully unpacks its contents. The box should contain the following items:

• One DES-1008D
• One external power adapter
• This User’s Guide.

If any item is found missing or damaged, please contact your local reseller for replacement.

Setup

The setup for the DES-1008D can be performed using the following steps:

• The surface must support at least 1.5 Kg for the DES-1008D.
• The power outlet should be within 1.82 meters (6 feet) of the DES-1008D.
• Visually inspect the DC power jack and make sure that it is fully secured to the power adapter.
• Make sure that there is proper heat dissipation from and adequate ventilation around the DES-1008D. Do not place heavy objects on the DES-1008D.

IDENTIFYING EXTERNAL COMPONENTS

This section identifies all the major external components of the DES-1008D. Both the front and rear panels are shown followed by a description of each panel feature. The indicator panel is described in detail in the next chapter.

Front Panel

The figure below shows the front panel of the DES-1008D.

LED Indicator Panel

Refer to the LED Indicator section for detailed information about each of the DES-1008D’s LED indicators.

LED Indicators

• Power Indicator (PWR)
  This indicator lights green when the hub is receiving power, otherwise, it is off.

• Loop Detect (LOOP)
  When this indicator lights amber, it means that there is a loop detected, then the network needs to be re-configuration.

• Full-Duplex/Collision (Full-Duplex/Collision)
  This LED indicator lights green when a respective port is in full duplex (FDX) mode. Otherwise, it is blinking when collisions are occurring on the respective port.

• 100M Link/Activity, 10M Link/Activity (100M LINK/ACT(green), 10LINK/ACT(amber))
  This indicator lights green when the port is connected to a 100Mbps Fast Ethernet station if the indicator blinks green will be transmitted or received data on the 100Mbps network. Otherwise, if the indicator light amber when the port is connected to a 10Mbps Ethernet station, if the indicator blinking amber will be transmission or receive data on the 10Mbps network.

Rear Panel

• 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. Since the DES-1008D does not include a power switch, plugging its power adapter into a power outlet will immediately power it on.

• MDI-X Jacks: Use these jacks to connect stations to the hub. These are MDI-X (Medium-Dependent Interface, Cross-wired) jacks, which mean, you can use ordinary straight-through twisted-pair cables to connect user machines and servers to the hub through them. If you need to connect another device with an MDI-X jack, such as another hub or an Ethernet switch, you should use a crossover cable, or make the connection using the MDI-X jack
  (described below).

• Uplink Jack(s) (MDI-II): Use this jack to connect stations to the hub. This is an MDI-II (Medium-dependent Interface, straight-wired) jack, which means you can connect the hub to a device with an MDI-X port using an ordinary straight-through cable, making a crossover cable unnecessary.

CONNECTING THE DES-1008D

This chapter describes how to connect the DES-1008D to your Fast Ethernet network. In each of the following figures, the DES-1008D is shown.

PC to DES-1008D

A PC can be connected to DES-1008D via a two-pair Category 3, 4, and 5 UTP/STP straight cable. The PC (equipped with an RJ-45 10/100Mbps phone jack) can be connected to any of the 8 ports (1x – 8x).] The LED indicators for PC connection depend on the LAN card’s capabilities. If LED indicators are not lit after making a proper connection, check the PC LAN card, the cable, and the DES-1008D conditions and connections. The following are LED indicator possibilities for a PC to DES-1008D connection:

1. The “100LINK/ACT,10LINK/ACT” LED indicator lights green for hookup to 100Mbps speed or light amber for hookup to 10Mbps speed.
2. The “Full-Duplex/Collision” LED indicator depends upon LAN card capabilities for full duplex or half duplex.

Hub to DES-1008D

A hub (10 or 100BASE-TX) can be connected to the DES-1008D via two-pair Category 3, 4, 5 UTP/STP straight cables. The connection is accomplished from the hub uplink (MDI-II) port to any of the DES-1008D (MDI-X) ports: 1x – 8x for the DES-1008D.

• 10BASE-T Hub
  For a 10BASE-T hub, the DES-1008D LED indicators should light up as the following:

  • The “Full-Duplex/Collision” indicator is OFF.
  • The “100LINK/ACT,10LINK/ACT LED” indicator is light amber.

• 100BASE-TX Hub
  For a 100BASE-TX hub, the DES-1008D LED indicators should light up as the following:

  • The “Full-Duplex/Collision” LED indicator is OFF.
  • The “100LINK/ACT,10LINK/ACT” LED indicator is light green.

Hub without Uplink (MDI-II) port

If a hub is not equipped with an uplink (MDI-II) port, the connection can be made using either a straight cable or a crossover cable.

• Using straight cable
  When using a straight cable, the connection can be made from the uplink (MDI- II) port of the DES-1008D to any port of the hub.

• Using crossover cable
  When using a crossover cable, the connection can be made from any (MDI-X) ports of the DES-1008D to any port of the Hub.

DES-1008D to switch (other devices)

The DES-1008D can be connected to another switch or other devices (routers, bridges, etc.) via a two-pair Category 3, 4, 5 UTP/STP straight or crossover cable.

• Using straight cable
  When using a straight cable, this is done from the uplink (MDI-II) port of the DES-1008D (DES-1008D A) to any of the 10Mbps or 100Mbps (MDI-X) port of the other switch (switch B) or other devices.

• Using crossover cable
  When using a crossover cable, this is done from any (MDI-X) port of the DES- 1008D (DES-1008D A) to any of the 10Mbps, 100Mbps (MDI-X) port of the other switch (switch B) or other devices.

1. The “100LINK/ACT,10LINK/ACT” LED indicator is light green for hookup to 100Mbps speed or light amber for hookup to 10Mbps speed.
2. The “Full-Duplex/Collision” LED indicator depends upon LAN card capabilities for full-duplex or half-duplex

Port Speed & Duplex Mode

After plugging the selected cable to a specific port, the system uses auto- negotiation to determine the transmission mode for any new twisted-pair connection:
If the attached device does not support auto-negotiation or has auto- negotiation disabled, an auto-sensing process is initiated to select the speed and set the duplex mode to half-duplex.

RJ-45 PIN SPECIFICATION

When connecting your DES-1008D to another switch, a bridge, or a hub, a modified crossover cable is necessary. Please review these products for matching cable pin assignment. The following diagram and tables show the standard RJ-45 receptacle/connector and their pin assignments for the switch- to-network adapter card connection, and the straight / crossover cable for the DES-1008D-to-switch/hub/bridge connection.
