Safety Instructions (continued)
•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
yourserviceprovider orlocalpowercompany.
•To help avoid damaging your system, be sure the voltage selection Switch (if provided)
onthepowersupply is set tomatch thepoweravailableat your location:
– 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far
Eastern countriessuch as South Korea andTaiwan
– 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan.
– 230 V/50 Hz inmost ofEurope,theMiddle East, andthe Far East.
•Also be sure that attached devices are electrically rated to operate with the power
available in your location.
•Use only approvedpower 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 cablethat is approved for use in your country. Thepower cablemust beratedfor
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
markedon theproduct.
•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 ensure proper grounding. Do not use adapter plugs or remove the grounding
prongfrom a cable. If youmust use an extension cable, use a 3-wire cable with properly
grounded plugs.
•Observe extension cable and power strip ratings. Make sure that thetotalampere rating
of all products plugged into the extension cable or power strip does not exceed 80
percent of theampereratings limit fortheextension cableorpowerstrip.
•To help protect your system from sudden, transient increasesand 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 surethat 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 wiringrules.
•When connecting or disconnecting power to hot-pluggable power supplies, if offered
withyour system,observethefollowing guidelines:
– Installthepowersupply beforeconnectingthepower cableto thepower supply.
– Unplug the power cable before removingthe power supply.
– Ifthe system hasmultiple sources of power, disconnect power from the system
by unplugging all power cables from the power supplies.

Safety Instructions (continued)
•Move products with care; ensure that all casters and/or stabilizers are firmly connected
to the system.Avoid sudden stopsand uneven surfaces.
General Precautions for
Rack-Mountable Products
•Observethe 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
systemas well astovarious peripheralsor supporting hardware.
CAUTION:
Installingsystems in a rackwithoutthe frontand
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
mayresultinserious 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 therack.

Safety Instructions (continued)
•Always load the rack from the bottom up, and load the heaviest item in the rack first.
•Make surethat the rack is level and stable before extending a component fromthe rack.
•Use caution when pressing the component rail release latches and sliding a component
intoorout ofa rack;the sliderailscanpinchyourfingers.
•After a component is inserted into the rack, carefully extend the rail into a locking
position,andthen slidethecomponent into therack.
•Do not overloadthe AC supply branch circuit that provides powerto the rack.Thetotal
rack load should not exceed 80 percent of the branch circuit rating.
•Ensurethat proper airflow is provided to components in the rack.
•Do not step on or standon 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 you are uncertain that suitable
grounding is available.
CAUTION: The system chassis mustbe positivelygrounded
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 gro
und 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 beforeyoutouch any of the electronic components,
such as the microprocessor. You can do so by periodically touching an unpainted metal
surface on thechassis.
You can alsotake thefollowing stepsto 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 youare ready to
installthecomponent in your system. Just before unwrappingtheantistatic
packaging, be sureto discharge static electricity from your body.
2. When transporting a sensitive component,first place it in an antistatic containeror
packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic
floor pads, workbench pads, and an antistatic grounding strap.

Switch Description
The 16-port DGS-1016T and 24-port DGS-1024T Switches provide dedicated
10, 100 or 1000 Mbps Ethernet bandwidth on each port. The ports will
automatically detect the speed, duplex and MDI/MDIX status of the device it
is connecting to,and adjust these settings accordingly.The Switch ports can be
used to network computers, printers, servers, routers, other switches or any
device equipped with an Ethernet port. For best performance, use Category 5
orbetterEthernet cabling.
This stand-alone Switch is very easy to set up, there is no network
management required. Just power on the Switch and connect the cables. Keep
in mind however that the standard rules of Ethernet regarding cable length
apply to this and all Ethernet devices. The length ofan Ethernet cable fromone
device to another cannot exceed 100 meters (or 300feet).
