INTRODUCTION

This chapter describes the features of the DES-1526 and some background information about Fast Ethernet, Gigabit Ethernet, Switching, VLAN , and Power over Ethernet technologies.

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 nondisruptive and smooth evolution nature, and the dominating potential market base, virtually guarantees cost -effective and high performance Fast Ethernet solutions.

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 CSMA/CD Ethernet protocol. Since 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.

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 hundred-fold 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 support for 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 NIC's 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 and tomorrow's rapidly improving switching and routing internetworking technologies.

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 do not compete with each other for network transmission capacity.

The switch acts as a high-speed selective bridge between the individual segments. The switch, 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.

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.

VLAN (Virtual Local Area Network)

A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency and the need for routers, using faster switching instead. Other VLAN utility includes:

u Security: Security is increased with the reduction of opportunity in

eavesdropping on a broadcast network because data will be switched to only those confidential users within the VLAN.

u Cost Reduction: A VLAN can be used to create multiple broadcast

domains, thus eliminating the need of expensive routers.

u 802.1Q VLAN: The VLAN tagging option is a standard set by the

IEEE to facilitate the spanning of VLANs across multiple switches. (Reference: IEEE Std 802.1Q-1998 Virtual Bridged Local Area Networks.)

Power over Ethernet (PoE)

Power over Ethernet (PoE) integrates power and data onto one single cabling infrastructure, eliminating the need to have AC power available at all locations.

Power and Data are integrated onto the same cable. Supporting category 5/5e up to 100 Meters , PoE will provide power to PoE compatible devices, such as IP telephones, wireless LAN access points, and IP security cameras.

PoE is already widely adopted in the market, saving up to 50% of overall installation costs by eliminating the need to install separate electrical wiring and power outlets.

u One DES-1526 u One AC power cord, suitable for your area’s electrical power

connections

u Four rubber feet to be used for shock cushioning u Screws and two mounting brackets u CD-ROM with Web Management Utility and Manual

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

Installation

The site where you install the Switch stack may greatly affect its performance. When installing, consider the following pointers:

u Install the Switch in a fairly cool and dry place. See Technical

Specifications for the acceptable temperature and humidity

operating ranges.

u Install the Switch in a site free from strong electroma gnetic

field generators (such as motors), vibration, dust, and direct exposure to sunlight.

u Leave at least 10cm (4 in.) of space at the front and rear of the

Switch for ventilation.

u Install the Switch on a sturdy, level surface that can support

its weight, or in an EIA standard-size equipment rack. For information on rack installation, see the next section, titled Rack Mounting.

u When installing the Switch on a level surface, attach the

rubber feet to the bottom of each device. The rubber feet cushion the Switch and protect the Switch case from scratching.

Installing the Switch on a Desktop

When installing the Switch on a desktop or shelf, the rubber feet included with the Switch should first be attached. Attach these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space between the Switch and any other objects in the vicinity.

Figure 1. Installed on a Desktop

Installing the Switch on a Rack

The Switch can be mounted in an EIA standard -size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the Switch’s front panel (one on each side), and secure them with the provided screws.

Figure 2. Combine the Switch with the provided screws .

Then, use screws provided with the equipment rack to mount each switch in the rack.

Figure 3. Mount the Switch in the rack .

Connecting Network Cables

The Switch supports 24 10/100BASE -TX Fast Ethernet PoE enabled ports and 2 1000BASE-T/mini-GBIC combo ports. These 24 PoE ports will be automatically activated when a compatible terminal is identified. The Switch will supply power through the PoE port to the connected PD.

For Legacy devices that are not yet compatible , the PoE port will not offer the power to these devices. This feature allows users to freely and safely mix legacy and Power over Ethernet compatible devices on their network.

The Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet and it runs both in half- and full- duplex mode using two pairs of Category 5 cables.

The Switch also supports 2 1000BASE-T/mini-GBIC combo Gigabit Ethernet ports. When using the RJ-45 ports, it runs in Autonegotiation mode with 10/100Mbps that runs in both half- and fullduplex mode and 1000Mbps that runs in full-duplex mode using four pair Category 5. When using the mini -GBIC ports, it runs in optional 1000BASE -SX/LX fiber connectivity with mini-GBIC transceiver module. The Combo Gigabit Ethernet port will run only one of the mini -GBIC ports or RJ-45 ports The mini-GBIC port priority is higher than the RJ -45 port, therefore if both the mini-GBIC port and RJ-45 port are connected, then only the mini -GBIC will activate.

be turned on without having any or all LAN segment cables connected.

IDENTIFYING E XTERNAL COMPONENTS

This chapter describes the front panel, rear panel, and LED indicators of the Switch.

Front Panel

The figure below shows the front panels of the Switch.

Figure 5. Front panel view

LED Indicator:

Comprehensive LED indicators display the status of the Switch and the network (see the LED Indicators chapter below).

10/100Mbps PoE Ports (Port 1~24):

These ports are PoE enable ports. These PoE ports will be automatically activated when a compatible terminal is identified, and the PoE port will supply power to the connected PoE device.

The Switch PoE function supports PoE ports priority management. When there is a system power shortage with the PD, the Switch will enforce the PoE port priority management; the lower port number will have the higher priority than the higher port number, Port 1 > Port 2 > … > Port 24.

For legacy devices that are not yet compatible , the PoE port will not offer the power to these devices. This feature allows users to freely and safely mix legacy and Power over Ethernet compatible devices on their network.

These ports support network speeds of either 10Mbps or 100Mbps, and can operate in half- and full-duplex transfer modes. These ports also support the automatic MDI/MDIX crossover detection function, providing true “plug and play” capability. Just plug-in the network cable to the Switch directly and regardless if the end node is a NIC (Network Interface Card) or switch and Switch.

1000BASE-T Gigabit Ethernet Ports (Port 25~26):

The Switch is equipped with two Gigabit twisted pair ports, supported auto negotiable 10/100/1000Mbps and auto MDI/MDIX crossover detection function. These two ports can operate in half-duplex mode for 10/100Mbps and full-duplex mode for 10/100/1000Mbps.

Note: When the port is set to “Forced Mode”, the Auto MDI/MDIX will be disabled.

mini-GBIC Ports (Port 25F~26F):

The Switch is equipped with two mini -GBIC ports, which supports optional 1000BASE-SX/LX mini-GBIC modules.

Note: Port 25 and 26 are the same ports with the mini-GBIC Port 25F and 26F ports, when plug in the mini -GBIC module, the device will activate mini-GBIC, and the RJ -45 port will be disabled.

Reset:

The Reset button is to reset all settings back to the factory defaults.

Note: Be sure that you record the settings of your device, or else all settings will be erased when pressing the “Reset” button.
