Please pay careful attention to the following safety guidelines to ensure your own personal safety and to help protect
your system from potential damage.
Safety Cautions
To greatly reduce the risk of physical injury, electrical shock, fire, and damage to equipment, observe the following
precautions.
Observe and follow service markings.
•Do not attempt to service any product, except when it is explained in the system’s documentation.
•Opening or removing covers that are marked with this ( ) symbol may expose the user 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 immediately and replace the part
or contact your trained service provider:
•Damage to the power cable, extension cable, or plug.
•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 the operating instructions are correctly followed.
General safety cautions:
•Keep the system away from radiators and heat sources. Also, do not block cooling vents.
•Do not spill food or liquids on system components, and never operate the product in a wet environment. If the
system gets wet contact your trained service provider.
•Do not push any objects into the openings of the system. Doing so can cause fire or electric shock by shorting
out interior components.
•Only use this product with approved equipment.
•Allow the product to cool before removing the cover or touching internal components.
•Operate the product only from the type of external power source indicated on the electrical ratings label. If
unsure of the type of power source required, consult your service provider or local power company.
•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 AC-powered 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 using an extension cable is necessary, use a 3-
wire cable with properly grounded plugs.
•Observe the 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 the 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.

DWS-3160 Series Gigabit Ethernet Unified Switch Hardware Installation Guide
vii
•Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local or national wiring rules.
When connecting or disconnecting power to and from hot-pluggable power supplies, 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 and ensure that all casters and stabilizers are firmly connected to the system. Avoid
sudden stops and uneven surfaces.
To help avoid damage to the system, be sure that the voltage selection switch, on the power supply, is set to match
the power available at the switch’s location:
•115V/60Hz is used mostly in North and South America as well as Far Eastern countries like as South Korea
and Taiwan
•100V/50Hz is used mostly in Eastern Japan and 100V/60Hz in Western Japan
•230V/50Hz is used mostly in Europe, the Middle East, Africa and the Far East
General Precautions for Rack-Mountable Products
Please pay careful attention to the following precautions concerning rack stability and safety. Systems are considered
to be components in a rack. Thus, a component refers to any system, as well as to various peripherals or supporting
hardware.
CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause the
rack to tip over, potentially resulting in serious injury. After installing system/components in a rack,
never pull more than one component out of the rack on its slide assemblies at one time. The weight of
more than one extended component could cause the rack to tip over and may result in serious injury.
•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.
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
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. Completed power and
safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard will exist
if the safety ground cable is omitted or disconnected.

Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside the system. To prevent static damage, discharge static
electricity from your body before touching any of the electronic components, such as the microprocessor. This can be
done by periodically touching an unpainted metal surface on the chassis.
The following steps can also be taken 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 ready to install the component in the 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.

Installation Guidelines
This section will discuss the hardware installation guidelines that the user must follow in order to properly and safely
install this Switch into the appropriate environment.
•Visually inspect the power cord and see that it is fully secured to both the power connector, on the Switch, and
the electrical outlet, that supplies power.
•Install the Switch in a fairly cool and dry place within the acceptable temperature and humidity operating
ranges.
•Install the Switch in a site free from strong electromagnetic field generators such as motors, vibration, dust,
and direct exposure to sunlight.
Installing the Switch without a Rack
This section is used to guide the user through installing the Switch in an area other than a switch rack. Attach the
rubber feet included to the bottom of the Switch. Take note that there should be marked blocks on the bottom of the
Switch to indicate where to attach the rubber feet. These marking are usually found at each bottom corner of the
device. The rubber feet cushion the Switch, protecting the casing from scratches and preventing it from scratching
other surfaces.
Figure 2- 1. Prepare the Switch for installation on a desktop or shelf
Install the Switch on a sturdy, level surface that can support the weight of the Switch (see the Appendix section for the
weight specifications of each Switch). Do not place any heavy objects on the Switch. The power outlet should be
within 1.82 meters (6 feet) of the Switch.
Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. Leave at least 10 cm
(4 inches) of space at the front and rear of the Switch for ventilation.
Installing the Switch into a Rack
This section is used to guide the user through installing the Switch into a switch rack. The Switch can be mounted in a
standard 19"(1U) rack using the provided mounting brackets. Use the following diagram as a guide.

Figure 2- 2. Fasten mounting brackets on the Switch
Fasten the mounting brackets supplied to the sides of the Switch using the screws provided. With the brackets
attached securely, the Switch can be mounted in a standard rack, as shown below.
Figure 2- 3. Installing the Switch in a rack
Make sure that there is adequate space around the Switch to allow for proper air flow, ventilation, and cooling.
Installing SFP transceivers into the SFP Ports
The Switch is equipped with small form-factor pluggable (SFP) ports (otherwise known as Mini-GBIC ports) that can
be used to connect various other networking devices to this Switch that do not support the standard copper wiring
connection. These ports are generally used to connect this Switch to networking devices that can only be accessed
via an optical fiber connection and is normally used for a connection that spans greater distances. The maximum
distance that the copper wiring connection can reach is 100 meters. Fiber optic connections can span over several
kilometers.
The figure below illustrates how to properly insert SFP transceivers into the Switch’s SFP ports.

A complete list of SFP transceivers, compatible with this Switch, can be found in the Appendix section, at the end of
this document.
Connecting to a Redundant Power Supply
This Switch can be connected to the Redundant Power Supply (RPS) using either a 14-pin DC power cable or a 22-
pin DC power cable. A standard, three-pronged AC power cable connects to the redundant power supply and the
main power source to provide power to the RPS. The external redundant power supply is only used when the internal
power supply fails. After the internal power supply fails, the external RPS will immediately take over the power
supplying duties to the Switch automatically.
Please note that every Switch within this series will make use of a specific RPS.
The DWS-3160-24TC must be used together with the DPS-200 Redundant Power Supply or an equivalent RPS.
The DWS-3160-24PC must be used together with the DPS-700 Redundant Power Supply or an equivalent RPS.
Redundant Power Supply, the DPS-200
The D-Link, DPS-200, External Redundant Power Supply, provides a backup power solution to the DWS-3160-24TC
Switch in the event that the Internal Power Supply fails. The DPS-200 is a standalone, low-cost, simple solution that
can prevent the Switch from shutting down when the Internal Power Supply fails. This option is imperative when the
availability of this Switch on the network is of high importance.

Figure 2- 5. Connecting the DWS-3160-24TC to the DPS-200
To connect the DPS-200 to the Switch for the first time, follow these steps:
1. Disconnect the power cable from the power connector of the Switch.
2. Interlink the RPS ports of the Switch and the DPS-200 by using the 14-pin DC power cable, supplied with the
RPS.
3. Interlink the Power connector, of the DPS-200, and the grounded electrical outlet by using a standard AC
power cable. A green LED on the front of the DPS-200 will illuminate to indicate a successful connection.
4. Reconnect the power cable to the power connector of the Switch.
5. No software configuration is needed for this installation.
CAUTION: Do NOT use the DWS-3160-24TC Switch with any Redundant Power System other
than the DPS-200.
Redundant Power Supply, the DPS-700
The D-Link, DPS-700, External Redundant Power Supply, provides a backup power solution to the DWS-3160-24PC
Switch in the event that the Internal Power Supply fails. The DPS-700 is a standalone, low-cost, simple solution that
can prevent the Switch from shutting down when the Internal Power Supply fails. This option is imperative when the
availability of this Switch on the network is of high importance.

RPS Rack-Mountable Chassis, the DPS-800
Because of the small size of the DPS-200, the DPS-800 can be used to house and mount the DPS-200 into a switch
rack. The DPS-800 is a standard-size rack mount (1U) designed to hold up to two DPS-200 redundant power
supplies. Using this rack mount chassis, will allow the user to save space when deploying the DPS-200 RPS’s into a
switch rack.
