Throughout this document, the caution icon ( ) is used to indicate cautions and precautions that you need to review and follow. Safety Cautions 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 electrical shock. Only a trained service technician should service components inside these compartments. · If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your trained service provider: · · · · · The power cable, extension cable, or plug is damaged. An object has fallen into the product. The product has been exposed to water. The product has been dropped or damaged. The product does not operate correctly when you follow the operating instructions. · · · · · · · Keep your system away from radiators and heat sources. Also, do not block cooling vents. Do not spill food or liquids on your system components, and never operate the product in a wet environment. If the system gets wet, see the appropriate section in your troubleshooting guide or contact your trained service provider. Do not push any objects into the openings of your system. Doing so can cause fire or electric shock by shorting out interior components. Use the product only with approved equipment. Allow the product to cool before removing covers or touching internal components. Operate the product only from the type of external power source indicated on the electrical ratings label. 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 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 ­48 VDC for DC power supply unit on DES-3526DC only · · Also, be sure that attached devices are electrically rated to operate with the power available in your location. Use only approved power cable(s). If you have not been provided with a power cable for your system or for any ACpowered 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 electric shock, plug the system and peripheral power cables into properly grounded electrical outlets. These cables are equipped with three-prong 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 3-wire cable with properly grounded plugs. viii · xStack DES-3526 / DES-3526DC Layer 2 Stackable Fast Ethernet Managed Switch User Manual · · · · · 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 Rack-Mountable 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. · · Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware. 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. 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, regional 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. A qualified electrical inspector must inspect completed power and safety ground wiring. An energy hazard will exist if the safety ground cable is omitted or disconnected. ix · · · · · · · xStack DES-3526 / DES-3526DC Layer 2 Stackable Fast Ethernet Managed Switch User Manual 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. 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. 2. When transporting a sensitive component, first place it in an antistatic container or packaging. 3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads and an antistatic grounding strap. x xStack DES-3526 / DES-3526DC Layer 2 Stackable Fast Ethernet Managed Switch User Manual Section 1 Introduction Gigabit Ethernet Technology Switch Description Features Ports Front-Panel Components Side Panel Description Rear Panel Description Gigabit Combo Ports The DES-3526/DES-3526DC layer 2 Stackable Fast Ethernet switches are members of the D-Link xStack family. Ranging from 10/100Mbps edge switches to core gigabit switches, the xStack switch family has been future-proof designed to provide a stacking architecture with fault tolerance, flexibility, port density, robust security and maximum throughput with a user-friendly management interface for the networking professional. The following manual describes the installation, maintenance and configurations concerning members of the xStack DES3526/DES-3526DC switch series. These switches are identical in configurations and basic hardware and consequentially, most of the information in this manual will be universal all DES-3526/DES-3526DC switches. Corresponding screen pictures of the web manager may be taken from any one of these switches but the configuration will be identical, except for varying port counts. Please take note that if this device was purchased outside of Europe, certain cosmetic differences between the actual switch and images in this document will be apparent to the reader, such as the faceplate and the manual cover. The DES-3526/DES-3526DC has already joined the xStack family for the European market and is soon to be xStack converted, universally. Changes are made to the appearance of the device only and no configuration or internal hardware alterations occur. 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 using 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 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. Switch Description The DES-3526 is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or 100 Mbps bandwidth. The Switch has 24 UTP ports and Auto MDI-X/MDI-II convertible ports that can be used for unlinking to another switch. These ports can be used for connecting PCs, printers, servers, hubs, routers, switches and other networking devices. The dual speed ports use standard twisted-pair cabling and are ideal for segmenting networks into small, connected sub networks for superior performance. Each 10/100 port can support up to 200 Mbps of throughput in full-duplex mode. In addition, the Switch has 2 Mini-GBIC combo ports. These two-gigabit combo ports are ideal for connecting to a server or network backbone. 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.

Front-Panel Components The front panel of the Switch consists of LED indicators for power and for each 10/100 Mbps twisted-pair ports, and two 1000BASE-T Mini-GBIC ports. The ports of the DES-3526 and DES-3526DC are identical. Figure 1- 1. Front Panel View of the DES-3526 The DES-3526DC does not support a redundant power supply and therefore the RPS indicator does not appear on the front panel. Figure 1- 2. Front Panel View of DES-3526DC Comprehensive LED indicators display the status of the Switch and the network. 2 xStack DES-3526 / DES-3526DC Layer 2 Stackable Fast Ethernet Managed Switch User Manual LED Indicators The Switch supports LED indicators for Power, Console, RPS (DES-3526 only) and Port LEDs. The following shows the LED indicators for the DES-3526 along with an explanation of each indicator. LEDs and there corresponding meanings are displayed below. Figure 1- 3. LED Indicators on DES-3526 LED Power Console Description This LED will light green after the Switch is powered on to indicate the ready state of the device. The indicator is dark when the Switch is powered off. This LED should blink during the Power-On Self Test (POST). When the POST is finished, the LED goes dark. This indicator is lit sold green when the Switch is being logged into via out-of-band/local console management through the RS-232 console port in the back of the Switch using a straight-through serial cable. This LED will be lit when the redundant power supply is present and in use. Otherwise it will remain dark. One row of LEDs for each port is located above the ports on the front panel. The first LED is for the top port and the second one is for the bottom ports. These port LEDs will light two different colors for 10M and 100M. · · RPS (DES-3526 only) Port LEDs Amber - For speeds of 10 Mbps. A solid light denotes activity on the port while a blinking light indicates a valid link. Green - For speeds of 100 Mbps. A solid light denotes activity on the port while a blinking light indicates a valid link. 100M/10M Gigabit Ports These LEDs will light steady green to indicate that the port is transferring data at 100Mbps. The Switch's two Mini GBIC ports have their own corresponding LEDs: Speed - This LED will light solid green when the port is transferring at a rate of 1000Mbps. When dark, the port is transferring at 10/100Mbps. Link/Act - This LED will light solid green when there is a valid link. A blinking LED indicates current activity on the port. A dark LED indicates no activity on the port. 3 xStack DES-3526 / DES-3526DC Layer 2 Stackable Fast Ethernet Managed Switch User Manual Rear Panel Description The rear panel of the Switch contains an AC power connector. Figure 1- 4. Rear panel view of the DES-3526 The AC power connector is a standard three-pronged connector that supports the power cord. Plug-in the female connector of the provided power cord into this socket, and the male side of the cord into a power outlet. The Switch automatically adjusts its power setting to any supply voltage in the range from 100 ~ 240 VAC at 50 ~ 60 Hz. The rear panel also includes an outlet for an optional external power supply. When power fails, the optional external RPS will take over all the power immediately and automatically. Figure 1- 5. Rear panel view of DES-3526DC The rear panel of the DC power version of the Switch includes an opening designed to accommodate the DC power wiring assembly. See the installation instructions in this Section for details. Side Panel Description The right-hand side panel of the Switch contains a system fan, while the left hand panel includes a system fan and a heat vent. The system fans are used to dissipate heat. The sides of the system also provide heat vents to serve the same purpose. Do not block these openings, and leave at least 6 inches of space at the rear and sides of the Switch for proper ventilation. Be reminded that without proper heat dissipation and air circulation, system components might overheat, which could lead to system failure. Figure 1- 6. Side Panels 4 xStack DES-3526 / DES-3526DC Layer 2 Stackable Fast Ethernet Managed Switch User Manual Gigabit Combo Ports In addition to the 24 10/100 Mbps ports, the Switch features two Gigabit Ethernet Combo ports. These two ports are 1000BASE-T copper ports (provided) and Mini-GBIC ports (optional). See the diagram below to view the two Mini-GBIC port modules being plugged into the Switch. Please note that although these two front panel modules can be used simultaneously, the ports must be different. The GBIC port will always have the highest priority. Figure 1- 7.
