To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment observe the following precautions:
•Observe and follow service markings.
o Do not service any product except as explained in the system documentation.
oOpening or removing covers that are marked with the triangular symbol with a lightning bolt may expose the user to electrical shock.
oOnly 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:
oDamage to the power cable, extension cable, or plug.
o An object has fallen into the product.
o The product has been exposed to water.
o The product has been dropped or damaged.
oThe product does not operate correctly when the operating instructions are correctly followed.
•Keep your 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, see the appropriate section in the troubleshooting guide or 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.
•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 unsure of the type of power source required, consult your service provider or local power company.
•To help avoid damaging the system, be sure the voltage selection switch (if provided) on the power supply is set to match the power available at the Switch’s location:
o115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea and Taiwan
o 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
o230 V/50 Hz in most of Europe, the Middle East, and the Far East
•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 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 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.
v
xStack® DGS-3420 Series Layer 2+ Managed Stackable Gigabit Switch Hardware Installation Reference Guide
•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.
•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:
o Install the power supply before connecting the power cable to the power supply. o Unplug the power cable before removing the power supply.
oIf 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.
CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack. 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.
NOTE: A qualified electrician must perform all connections to DC power and to safety grounds. All electrical wiring must comply with applicable local 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 uncertain that suitable grounding is available.
vi
xStack® DGS-3420 Series Layer 2+ Managed Stackable Gigabit Switch Hardware Installation Reference Guide
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.

This LED will light green after powering the Switch on to indicate the ready state of the |
|
device. The indicator is dark when the Switch is no longer receiving power (i.e. powered |
|
off). |
|
|
Console |
This LED will blink green during the Power-On Self Test (POST). When the POST is |
|
finished, the LED goes dark. The indicator will light steady green when a user is logged in |
|
through the console port. |
RPS |
This LED will light green if the Redundant Powers Supply is in use. If the indicator is off, the |
|
RPS is not in use. When the switch detects that the RPS is connected, the light will be |
|
blinking. |
SD |
This LED will light green if a Secure Digital (SD) card is plugged in. When the Switch is |
|
reading or writing, the indicator will blink green. No light LED means there is no link. A solid |
|
red LED indicates SD card failure. |
|
|
Stack ID |
For standalone Switches, this will display number “1”. For stacked Switches, this indicates |
|
the position in the stacking box ID. The box ID is assigned either by the user (static mode) |
|
or by the system (automatic mode). When “1” to “12” is displayed, this indicates the |
|
stacking position of the switch. An “H” indicates the device was assigned as the stacking |
|
Master. “h“ means the device was selected to be the Backup Master. A “G” is displayed |
|
when the Safeguard Engine feature enters the exhausted mode. |
Link/Act LEDs |
The Switch has LED indicators for Link and Activity. The LED will light steady green when |
|
there is a secure connection (or link) to a 1000Mbps Ethernet device at any of the ports, or |
|
steady orange when there is a secure connection (or link) to a 10/100Mbps Ethernet device |
|
at any of the ports. The LED will blink green when a 1000Mbps port is active, or blink |
|
orange when a 10/100Mbps port is active. The LED remains dark when there is no link or |
|
activity. |
|
|
PoE |
Only the DGS-3420-28PC and the DGS-3420-52P switches are equipt with a PoE LED. |
|
When this light is on with a solid green light, it means that the corresponding ports are |
|
feeding power to the PoE devices plugged in. When this light is on with a solid orange light, |
|
it means that the port is in an error condition state. When this light is off, it means that the |
|
ports are not supplying power to the devices plugged into the ports. |

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 the power setting to any supply voltage in the range from 100~240 VAC at 50~60 Hz. An optional external Redundant Power Supply (DPS-500 for DGS-3420-28TC/28SC/26SC/52T, DPS-700 for DGS-3420-28PC/52P) can be plugged into the RPS outlet displayed above. When the internal power fails, this optional external RPS will take over all the power immediately and automatically.

Side Panel Components
The system heat vents located on each side dissipate heat. Do not block these openings. 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 or even severely damage components.

Installation Guidelines
Please follow these guidelines for setting up the Switch:
•Install the Switch on a sturdy, level surface that can support at least 6.6 lb. (3kg – This is without PoE functionality) of weight. 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 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.
•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 strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.
•When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet cushion the Switch, protect the casing from scratches and prevent it from scratching other surfaces.

Power On (AC Power)
1.Plug one end of the AC power cord into the power connector of the Switch and the other end into the local power source outlet.
2.Once the system is powered on, the LED’s blink green to indicate that the system is resetting.
Power Failure (AC Power)
In the event of a power failure, just as a precaution, unplug the Switch. After the power returns, plug the switch back in to the power socket.
CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack. After installing components in a rack, do not 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 injury.
Alarm Connector
The alarm connector can be used to use external devices when triggered events occur.
