Throughout this document, the cauti on icon ( ) is used to indicate cautions and precautions that you need to review and follow. Safety Cautions To redu ce t he risk of bodily injury, electri cal shock, fire and damage to the equipm ent, observe the following precautions. • Observe an d fo llow service mark ings. D o no t s ervice any p roduct ex cept as expl ained 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 pr oduct from the electri cal outlet and re place the part o r 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 liqui ds on your system components, and never operate the product in a wet enviro nment. If the system gets wet, see the appro priate se ction in your trouble shooting guide or co ntact your trained service provider. • Do n ot pu sh any obje cts into the op enings of your system. Doing so can cause fi re or electri c sho ck 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 avoi d damaging your system, be su re the voltage on th e power supply is set to match the p ower available at your location: 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries 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 48VDC for DES-3528DC • Also, be sure that attached devices are electrically rated to operate with the power available in your location. • Use only a pproved power cable(s). If you have not been provided with a power cable for y our system or for any AC-powered option intende d for yo ur system, purcha se a power cable that is approve d for use in your country. The power cable must be rated for the product and for the voltage and current marke d 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. vi

• To help prevent electric shock, plug the system and peripheral power cables into properly grounded electrical outlets. These cable s are equipped wi th three-p rong pl ugs to help ensu re p roper gro unding. Do not use adapter plugs or remove the grou nding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs. • Observe extensi on ca ble and powe r strip ratin gs. Make sure that the total ampere ratin g of all product s 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 n ot modi fy power cables or pl ugs. Co nsult a licensed el ectrician or your po wer company for site modifications. Always follow your local/national wiring rules. • When con necting or di sconnecting po wer to hot-pl uggable po wer su pplies, if offered with your syste m, 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 caste rs and/or stabilizers are firmly connected to the system. Avoid sudden stops and uneven surfaces. General Precautions for Rack-Mountable Products Observe the following preca utions for rack stabilit y and safe ty. Also, refer to the rack installation do cumentation 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 sy stem 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 re sts on the floor. In stall front a nd side sta bilizers on a si ngle 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, ca refully extend the rail into a lo cking position, and then slide the component into the rack. • Do not overload the AC su pply 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. vii

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 t he ground conductor or operate the equipment in the ab sence 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 gr ounded to th e rack cabin et frame. Do not attempt to conne ct powe r to the system until grounding cabl es 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. Protecting Against Electrostatic Discharge Static electri city can h arm delicate compon ents i nside y our system. To prevent static damag e, discharge stati c 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 t he component from the antistati c packin g ma terial until yo u are ready to install t he comp onent in y our system. Ju st bef ore 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 se nsitive components in a static-safe are a. If possible, use anti static floor pa ds, workbench pads and an antistatic grounding strap. viii

Section 1 Introduction Gigabit Ethernet Technology Switch Description Features Ports Front-Panel Components LED Indicators Rear Panel Description Side Panel Description Gigabit Combo Ports The DES-35 28/DES-3552 Series a re l ayer 2 Fa st Et hernet swit ches an d me mbers of the D-Lin k xStack ® family. Ranging from 10/100Mbps edge switches to core gi gabit switches, the xStack ® switch family has be en future-proof designed to provide a stacking architecture with fault tolera nce, flexibility, port density, robust security and maximum throughput with a user-friendly management interface for the networking professional. The following manual de scribes the in stallation, maintenance and configurations concerning the xStack ® DES-3528, DES-3528DC, DES-3528P, DES-3552 and DES-3552P switches. Please take note that if this device was purchased outside of Europ e, certai n cosmetic d ifferences b etween the a ctual switch a nd image s in this docum ent will be apparent to the rea der, such as the faceplate and th e manual cover. The DE S-3528/DES-3552 Series has already joined the xStack ® family for the Eu ropean 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. NOTE: For t he re mainder of this man ual, all versi ons of the DES-3528, DES-3528P, DE S- 3528DC, DES-3552 and DES-3552P switches will be referred to as simply the Switch or the DES-3528. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for full duplex, flow control, and manag ement objects, but with a t enfold increase in theoretical throu ghput over 100Mb ps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compati ble with all 10Mbp s and 100Mbps Ethernet enviro nments, Gigabit Ethernet provides a strai ghtforward upgrade without wasting a com pany's existing investment in hardware, software, and trained personnel. The in creased sp eed and extra ba ndwidth offe red by Gigabi t Ethernet a re essential to copi ng with the net work 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 enabl es fast optical fi ber connections to sup port video co nferencing, complex imaging, and simi lar data-intensive applications. Likewise, since data transfers occur 10 times fa ster than Fast Ethernet, servers o utfitted with Gigabit Ethernet NIC's are able to perform 10 times the number of operations in the same amount of time. In addition, the pheno menal band width delivered by Gigabit Et hernet 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-35 28/DES-3552 Switch Seri es is e quipped with unshielded twist ed-pair (UTP ) ca ble po rts providin g dedicated 10 or 100 Mbps bandwidth. The Switch has 24/48 UTP ports and Auto MDI-X/MDI-II convertible ports that can be used for uplinking to another switch. These ports can be used for conne cting PCs, printers, servers, hub s, 1

2 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 SFP combo ports. These two-gigabit combo ports are ideal for connecting to a server or network backbone. This stackable Switch enables the network to use some of the mo st demanding multimedia and imaging a pplications concurrently with other user applications without creat ing bottlene cks. The b uilt-in co nsole interface can be used to configure the Switch's settings for prio rity queuing, VLANs, and port trun k group s, port monitoring, and port speed.

The carton should contain the following items: • One xStack® stand-alone switch • One AC power cord* • Regi stration card • Mounting kit (two brackets and screws) • Four rubber feet with adhesive backing • RS-232 console cable If any item is found missing or damaged, please contact your local D-Link Reseller for replacement. * Please Note the DES-3528DC Switch does not require an AC power cord therefore none is provided. 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 o n a sturdy, level surface that c an su pport at least 6.6 lbs (3 kg) of weight for DES- 3528/DES-3528DC, at lea st 13.2 lb s (6 kg) of weigh t for DES-3552/DES-3528P, at least 1 5.4 lbs (7 kg) of weight for DES-3552P. 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 proper he at dissipation from and adequat e ventilation arou nd the Switch. Leave at least 10 cm (4 inches) of space at the front and rear of the Switch for ventilation. • Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges. • Install the Switch in a site free from st rong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. • When installing the Switch on a level surfa ce, attach the rubber feet to the bottom of the d evice. The rubber feet cushions help protect the casing from scratches and prevent it from scratching other surfaces. 11

Installing the Switch without the Rack When installing the Switch on a deskt op or shelf, the rubb er feet included with the Switch shoul d 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 2- 1.

Section 4 Introduction to Switch Management Management Options Web-based Management Interface SNMP-Based Management Connecting the Console Port (RS-232 DCE) First Time Connecting to the Switch Password Protection SNMP Settings IP Address Assignment Management Options This system may be man aged out-of-band through the con sole port on the fro nt panel o r in-band using Telnet. The user may also choose the web-based management, accessible through a web browser. Web-based Management Interface After you have su ccessfully installed the Switch, yo u can configure the Swit ch, monitor th e LED pa nel, and display statistics graphically using a Web browser, such as Mozilla Firefox or Microsoft® Inter net Explorer (v ersion 6.0 or later). SNMP-based Management You can manage the S witch with an SNMP-compatible console program. The Switch su pports SNMP version 1.0, version 2.0 and version 3.0. The SNMP agent decodes the incoming SNMP messages and responds to requests with MIB objects stored in the database. The SNMP agent updates the MIB objects to generate statistics and counters. Connecting the Console Port (RS-232 DCE) The Switch p rovides an RS-232 serial port that enables a co nnection to a computer or terminal for monitoring an d configuring the Switch. This port is a female DB-9 connector, impleme nted as a data co mmunications equipm ent (DCE) connection. To use the console port, you need the following equipment: A terminal or a computer with both a serial port and the ability to emulate a terminal. A null modem or Parallel RS-232 cable with a male DB-9 connector for the console port on the Switch. To connect a terminal to the console port: 1. Connect the male conne ctor of the RS -232 cable di rectly to the console po rt on the Switch, and tighten t he captive retaining screws. 2. Connect the other e nd of the cabl e to a terminal o r to the serial connector of a comp uter running terminal emulation software. Set the terminal emulation software as follows: 3. Select the appropriate serial port (COM port 1 or COM port 2). 4. Set the data rate to 115200 baud. 5. Set the data format to 8 data bits, 1 stop bit, and no parity. 6. Set flow control to none. 7. Und er Properties, select VT100 for Emulation mode. 17

8. Select Terminal keys f or Function, Arrow, an d Ctrl key s. Ensu re that you sele ct Te rminal keys (not Windows keys). NOTE: When you use HyperTerminal with the Microsoft® Windo ws® 2000 operating sys- tem, ensure that you have Windo ws 2000 Service Pack 2 or later installed. Wi ndows 2000 Service Pa ck 2 allows yo u to use arro w keys in HyperTerminal's VT100 em ulation. See www.microsoft.com for information on Windows 2000 service packs. 9. After you have correctly set up the terminal, plug the power cable into the power receptacle on the back of the Switch. The boot sequence appears in the terminal. 10. After the boot sequence completes, the console login screen displays. 11. If you have not logged into the command line interface (CLI) program, press the Enter key at the User n ame and password prompts. There is no default user name and password for the Switch. The administrator must first create user na mes and password s. If you have previou sly set up use r accounts, log in and contin ue to configure the Switch. 12. Enter the commands to complete you r desi red ta sks. Many commands requi re admini strator-level a ccess privileges. Read the n ext section f or mo re inf ormation on setting up use r acco unts. See t he DES-3528/DES-3552 Switch Series CLI Reference Guide on the do cumentation CD for a li st of all commands and additional information on using the CLI. 13. When you h ave co mpleted you r tasks, exit the session with t he log out co mmand or close th e em ulator program. 14. Make sure the terminal or PC you are using to make this connection is configured to match these settings. If you are having proble ms making this conne ction on a PC, ma ke sure the e mulation is set to VT-100. You will be able to set the emulation by clicking o n the File menu in you HyperTerminal window, clicking on Properties in the drop-down menu, and then clicking the Settings tab. This is where you will find the Emulation options. If you still d o not see anything, try rebooting the Switch by disconnecting its power supply. Once connected to the console, the screen below will appear on your console screen. This is where the user will enter commands to perform all the available management functions. The Switch will prompt the user to ente r a user name and a password. Upon the initial connection, there is no user name or password and therefore just press “enter” twice to access the command line interface.

First Time Connecting to the Switch The Switch supports user-based security that can allow you to pre vent unauthorized users from accessing the Switch or changing its settings. This section tells how to log onto the Switch. NOTE: The passwords used to access the Switch are case-sensitive; therefore, "S" is not the same as "s." When you first connect to the Switch, you will be presented with the first login screen. NOTE: Press Ctrl+R to ref resh the scre en. This command can be used at a ny time to force the console program in the Switch to refresh the console screen. Press Enter in both the Use rname and Pa ssword fields. Yo u will be gi ven acce ss to the com mand p rompt DES-3528:admin# shown below: There is no initial username or password. Leave the Username and Password fields blank. DES-3528 Fast Ethernet Switch Command Line Interface Firmware: Build 2.60.017 Copyright(C) 2010 D-Link Corporation. All rights reserved. Username: PassWord: DES-3528:admin# Figure 4- 2. Command Prompt NOTE: The first user automatically gets Administrator level privileges. It is recommended to create at least one Admin-level user account for the Switch. Password Protection The Switch does not have a default user name and password. One of the first tasks when settings up the Switch is to create user accounts. Once logge d in using a pred efined administrator-level user name, users will have privileged access to the Switch's management software. After your initial login, define new pa sswords for both def ault user na mes to prevent un authorized access to the Switch, and record the passwords for future reference. To create an administrator-level account for the Switch, follow these steps: At the CLI login prompt, enter create account admin followed by the and press the Enter key. The Switch will then prompt the user for a password. Type the used for the adm inistrator account being created and press the Enter key. Again, the user will be prompted to enter the same password again to verify it. Type the same password and press the Enter key. Successful creation of the new administrator account will be verified by a Success message. 19

NOTE: Passwords are ca se sensitive. User names and passwo rds can be up to 15 characters in length. The sample belo w illu strates a successful creati on of a new admi nistrator-level account with th e user n ame "newmanager". DES-3528:admin# create account admin newmanager Command: create account admin newmanager Enter a case-sensitive new password: ******** Enter the new password again for confirmation: ******** Success. DES-3528:admin# Figure 4- 3. New administrator level account NOTICE: CLI configuration commands only modify the running configuration file and are not saved when t he Switch is rebooted. To save all your configuration changes in n onvolatile storage, you m ust use th e save command to copy the running configuration file to the startup configuration. SNMP Settings Simple Net work Management Proto col (SNMP ) is an OS I La yer 7 (Appli cation Laye r) designed sp ecifically for managing an d monitorin g network dev ices. SNMP enabl es net work ma nagement station s to read and modify th e settings of gateways, routers, switches, and other network devices. Use SNMP to configure system features for proper operation, monitor performance and detect potential problems in the Switch, switch group or network. Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Manage ment Informatio n Base (M IB), which pro vides a sta ndard p resentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network. The Switch supports SNMP versions 1, 2c, and 3. You can specify which version of SNMP you want to use to monitor and control the Switch. T he three versions of SNMP vary in the level of se curity provided between the management station and the network device. In SNMP v.1 and v.2, use r authentication is accomp lished using ' community strings', which function like passwords. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not been authenticated are ignored (dropped). The default community strings for the Switch used for SNMP v.1 and v.2 management access are: • public - Allows authorized management stations to retrieve MIB objects. • private - Allows authorized management stations to retrieve and modify MIB objects. SNMP v.3 u ses a more sop histicated authenticati on pro cess that is sepa rated into two parts. The first part is to maintain a list of users an d their attribu tes that are a llowed to act as SNMP managers. The se cond part descri bes what each user on that list can do as an SNMP manager. The Switch allows groups of users to be listed and configured with a shared set of privileges. The SNMP version may also be set for a listed group of SNMP managers. Thus, you may create a group of SNMP managers that are allowed to view rea d-only information or receive traps u sing SNMP v.1 while assig ning a highe r level of secu rity to another group, granting read/write privileges using SNMP v.3. 20

Using SNMP v.3 individual use rs or groups of SNMP m anagers can be allowed to pe rform o r be restricted fro m performing specific SNMP management functions. The functions allowed or restricted are defined using the Object Identifier (OID) associated with a specific MIB. An additional layer of security is available for SNMP v.3 in that SNMP messages may be encrypted. To read more about how to configure SNMP v.3 settings for the Switch read the section entitled Management. Traps Traps are messages that alert network personnel of events that occur on the Switch. The events can be as serious as a reboot (so meone a ccidentally turne d OFF the Switch ), or less se rious like a port st atus ch ange. The Switch generates traps and se nds them to the trap recipient (or net work manager). Typical traps include trap messages for Authentication Failure, Topology Change and Broadcast\Multicast Storm. MIBs The Switch in the Management Information Base (MIB) stores management and counter information. The Switch uses the standard MIB-II Management Information Base m odule. Consequently, values for MIB o bjects can b e retrieved from any SNMP-based network management software. In addition to the s tandard MIB-II, the Switch also supports its own proprietary enterprise MIB as an extended Ma nagement Information Base. Specifying the MIB Object Identifier may also retrieve the proprietary MIB. MIB values can be either read-only or read-write. IP Address Assignment Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for exam ple BOOTP, TFTP). The Switch' s default IP address is 10.90.9 0.90. You can change the default Switch IP address to meet the specification of your networking address scheme. The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found by entering the command "show switch" into the command line interface, as shown below. DES-3528:admin#show switch Command: show switch Device Type : DES-3528 Fast Ethernet Switch Unit ID : 1 MAC Address : 00-21-91-AF-EA-00 IP Address : 10.90.90.90 (Manual) VLAN Name : default Subnet Mask : 255.0.0.0 Default Gateway : 0.0.0.0 Boot PROM Version : Build 1.00.B008 Firmware Version : Build 2.60.017 Hardware Version : A4 Serial Number : P1UQ287000012 System Name : System Location : System Contact : Spanning Tree : Disabled GVRP : Disabled IGMP Snooping : Disabled MLD Snooping : Disabled VLAN Trunk : Disabled Telnet : Enabled (TCP 23) Web : Enabled (TCP 80) CTRL+C ESC q Quit SPACE n Next Page ENTER Next Entry a All Figure 4- 4. Show switch command 21

The Switch's MAC address can also be found from the Web management program on the Switch Information (Basic Settings) window on the Configuration menu. The IP addre ss for the Switch must be set before it can be mana ged with the Web -based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known. The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows: Starting at the command line prompt, enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy Where the x's rep resent the IP addre ss to be assig ned to the IP interface n amed System and the y's repre sent the corresponding subnet mask. Alternatively, you can en ter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x's rep resent the IP address to be assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation. The IP interface named System on the Switch can be assigned an IP address and subnet mask, and then be used to connect a management station to the Switch's Telnet or Web-based management agent. DES-3528:admin#config ipif System ipaddress 10.90.90.90/255.0.0.0 Command: config ipif System ipaddress 10.90.90.90/8 Success. DES-3528:admin# Figure 4- 5. Assigning the Switch an IP Address In the above example, the Switch was assigned an IP address of 10.90.90.90 with a su bnet mask of 255 .0.0.0. (the CIDR form was used to set the address (10.90.9 0.90/8). The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet and the CLI or via the Web- based management. 22

Section 5 Web-based Switch Configuration Introduction Login to Web Manager Web-based User Interface Web Pages Introduction All softwa re functions of the Switch can be man aged, configu red an d mo nitored via th e embe dded Web-based (HTML) interface. The Switch can be m anaged from remote stations anywhere on the net work through a stand ard browser such as Mozilla Fi refox or Microsoft Internet Explorer. The browser acts as a universal access tool and can communicate directly with the Switch using the HTTP protocol. The Web-based management module and the console program (a nd Telnet) are diffe rent ways to acce ss the same internal switching software and configure it. Thus, all se ttings encountered in Web-based management are the sam e as those found in the console program. Login to Web Manager To begin m anaging the Switch, sim ply run the bro wser you ha ve installed o n your co mputer and p oint it to the IP address you have defined for the dev ice. Th e URL in the address bar sh ould read som ething like: http://123.123.123.123, where the numbers 123 represent the IP address of the Switch. NOTE: The Factory default IP address for the Switch is 10.90.90.90. This opens the management module's user authentication window, as seen below. Figure 5- 1. Enter Network Password dialog Enter “admin” in both the User Name and Password fields and click OK. This will open the Web-based user interface. The Switch management features available in the web-based manager are explained below. 23

Web-based User Interface The user interface provides access to various Switch configuration and management windows, allows you to view performance statistics, and permits you to graphically monitor the system status. Areas of the User Interface The figure below shows the user interface. The user interface is divided into three distin ct areas as described in the table. Area 2 Figure 5- 2.
