review and follow.
To reduce
the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions.
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 the 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 a fire or an 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 th e electrical ratings label. If you ar e
not sure of the type of power sour ce required, consult your service provider or local power co mpany.
To help avoid damaging your system, be sure the voltage selection Switch (if provided) 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 Japa n
– 230 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 provid ed 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 th e 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 an electric shock, plug the system and peripheral power cables into properly grounded electrical
outlets. These cables are equipped with three-prong plugs to help en sure 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.
Observe extension cable and power strip ratings. Make sur e that th e 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 ex tension 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 y
Always follow your local/national wiring rules.

DGS-3100 Series Gigabit Stackable Managed Switch User Manual
Whe
Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid sudden stops
and uneven surfaces.
n 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.
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 fro nt 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 lo cking 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 you are uncertain that suitable grounding is available.
vi
DGS-3100 Series Gigabit Stackable Managed Switch User Manual
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 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 and workbench pads and
an antistatic grounding strap.
Battery Handling Reminder
CAUTION: This is danger of explosion if the battery is incorrectly replaced. Replace only with the
same or equivalent type recommended by the manufacturer. Discard used batteries according to
the manufacturer's instructions.

The ‘Firmware Download’ web page is used to download the firmware files that will be used to manage the device.
NOTE: Firmware version 1.x.x supports 4 SKUs od DGS-3100 series: DGS-3100-24, DGS-310024P, DGS-3100-48 and DGS-3100-48P, Firmware version 2.x.x supports in addition the 5
DGS-3100-24TG.
Firmware version 2.x.x includes as well additional features comparing to version 1.x.x, for more
details, please refer to the Release Notes.

Upgrade Procedure – Important Note s:
ACL backward compatibility issue - In firmware 1.x.x, TCP/UDP ports of access profile are in hexadecimal instead of
decimal values. In version 2.x.x, TCP/UDP port value entries are in decimal value. However - if the user upgrades the
switch firmware from version 1.x.x to version 2.x.x, the value will be retained as hexadecimal value.
ACLs access rules priority did not work in firmware version 1.x.x. In firmware version 2.x.x, the priority is supported and it
is not allowed two identical access rules priority from different access profiles. If the user download configuration file from
version 1.x.x which including ACLs which has more than one rule, it might not work and there will be an error message.
The user can delete and create the ACLs again if he encountered a problem.
Tacacs/Radius backwards compatibility issue - In firmware version 1.x.x, it is possible to configure up to 4 Tacacs /Radius
servers. In firmware version 2.x.x, it is possible to configure up to 3 servers from each type. In addition to that it was not
required to configure priority to Tacacs server s in 1.x.x while in 2.x.x it is required. If the user configured 4 servers in
version 1.x.x and try to download the configuration to firmware 2.x.x, he will get an error message, the same event will
happened because of the Tacacs priority.
