xStack®DES-3528/DES-3552 Series Layer 2 Managed Stackable Fast Ethernet Switch Hardware Installation Guide
• 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 cabl e. If you must use an extens ion 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 ca nnot 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 ca re; 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. Th us, "component" refers to any sy stem as well as to
various peripherals or supporting hardware.
• Before working on the rack, make sure that the stab ilizers are secured to the rack, extended to the floor, and
that the full weight of the rack re sts o n the floor. In stall front a nd side sta bilizers on a si ngle ra ck 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 rele ase 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 ra ck 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 electri cian must perform all connections to DC power and to safety groun ds.
All electrical wiring must comply with applicable local, regional or national codes and practices.
CAUTION: Never defeat t he gro und conductor o r o perate th e e quipment 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 g round 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 unp acking a static-sensitive component from its shipping carton, do not remove t he co mponent 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.

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 incre ase in theoretical throu ghput over 100Mb ps
Fast Ethern et and a one hundred-fold increase ove r 10Mbp s Ethernet. Since it is compati ble with all 10Mbp s and
100Mbps Ethernet enviro nments, Gigab it Et hernet 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 freque ntly develop a s computers and their bu sses get faste r and more users usi ng 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 conne ctions to sup port video co nferencing, compl ex 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 ha s 24/48 UT P ports and Auto MDI-X/MDI -II convertible ports that
can b e used for uplin king to another switch. Th ese ports can be use d for conne cting PCs, printe rs, servers, hub s,

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.

Gigabit Combo Ports
In addition to the 24/48 10/100 Mbp s ports, the Switch feat ures two Giga bit Ethernet Combo ports. The se two port s
are 1000BASE-T copper ports (provided) and SFP p orts (optional). See the di agram below to view the t wo SFP port
modules bei ng plug ged i nto the Switch. Please n ote that although the se t wo front pa nel module s can be u sed
simultaneously. At the same time, only one copper port or one SFP port can link up for each combo po rt. The SFP
port will always have the highest priority.

Package Contents
Open the shi pping carton of the Switch and carefull y unpack its conte nts. Th e carton should contai n 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 in stall 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 fo r DES-3 552/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 dissipatio n 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 ru bber
feet cushions help protect the casing from scratches and prevent it from scratching other surfaces.
