Safety Instructions

Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage.

Throughout this safety section, the caution icon ( ) is used to indicate cautions and precautions that need to be reviewed and followed.

Safety Cautions

To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions.

•Observe and follow service markings.

•Do not service any product except as explained in the system documentation.

•Opening or removing covers that are marked with the triangular symbol with a lightning bolt 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 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.

•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:

•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 Japan

•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 provided with a power cable for your system or for any ACpowered 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.

xii

xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch

•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.

•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:

•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; 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.

xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch

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.

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.

Lithium Battery Precaution

CAUTION: Incorrectly replacing the lithium battery of the Switch may cause the battery to explode. Replace this battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturers instructions.

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.

Ethernet Technology

Fast Ethernet Technology

The DGS-3400 Gigabit Ethernet switches are members of the D-Link xStack family. Ranging from 10/100Mbps edge switches to core gigabit switches, the xStack switch family has been future-proof designed to deliver a system with fault tolerance, flexibility, port density, robust security and maximum throughput with a user-friendly management interface for the networking professional.

This manual describes the installation, maintenance and configurations concerning members of the xStack DGS-3400 Switch Series. These switches include: the DGS-3426, DGS-3426P, DGS-3427 and the DGS-3450. The xStack DGS-3400 Series switches are similar in configurations and basic hardware and consequentially, most of the information in this manual will be universal to the whole xStack DGS-3400 Series. Corresponding screen pictures of the web manager may be taken from any one of these switches but the configuration will be identical, except for varying port counts.

Switch Description

D-Link's next-generation xStack DGS-3400 Series switches are high port-density stackable switches that combine the ultimate performance with fault tolerance, security, management functions with flexibility and ease-of-use. All these features, typically found in the more expensive chassis-based solutions, are available from the xStack DGS-3400 switch series at the price of a stackable switch!

All xStack DGS-3400 Series switches have some combination of 1000BASE-T ports, SFP ports and 10-Gigabit ports that may be used in uplinking various network devices to the Switch, including PCs, hubs and other switches to provide a gigabit Ethernet uplink in full-duplex mode. The SFP (Small Form Factor Portable) combo ports are used with fiber-optical transceiver cabling in order to uplink various other networking devices for a gigabit link that may span great distances. These SFP ports support fullduplex transmissions, have auto-negotiation and can be used with DEM-310GT (1000BASE-LX), DEM-311GT (1000BASE-SX), DEM-314GT (1000BASE-LH), DEM-312GT2 (100BASE-SX) and DEM-315GT (1000BASE-ZX) transceivers. Users may also use one of the WDM Single Mode Transceivers, such as the DEM-330T/R or the DEM-331T/R. The rear panel of the xStack DGS-3400 Switches Series includes spaces for optional single-port module inserts for single port 10GE XFP or 10GBASE-CX4 modules used for backbone uplink or stacking connection to another xStack DGS-3400 Series Switch.

The Optional Module

The rear panel of the DGS-3426, DGS-3426P, DGS-3427 and DGS-3450 include open slots that may be equipped with the DEM410X 1-port 10GE XFP stacking uplink module, or a DEM-410CX 1-port 10GBASE-CX4 stacking uplink module, both sold separately. These modules may be used to stack switches in a switch stack using a Duplex Ring or Duplex Chain topology.

Adding the DEM-410X optional module will allow the administrator to transmit data at a rate of ten gigabits a second. The module port(s) are compliant with standard IEEE 802.3ae, support full-duplex transmissions only and must be used with XFP MSA compliant transceivers.

The DEM-410CX uses copper wire medium, not optic fiber and therefore has a transmit length limit up to 1 meter. Compliant with the IEEE802.3ak standard, this module uses a 4-laned copper connector for data transfer in full-duplex mode within a stacking configuration.

To install these modules in the DGS-3400 Series Switch, follow the simple steps listed below.

CAUTION: Before adding the optional module, make sure to disconnect all power sources connected to the Switch. Failure to do so may result in an electrical shock, which may cause damage, not only to the individual but to the Switch as well.

At the back of the Switch to the left is the slot for the optional module. This slot must be covered with the faceplate if the slot is not being used. If a module will be installed in an available slot, the faceplate is easily removed by loosening the screws and pulling off the plate.

The front panels of the available modules are shown here:

Figure 2- 20. Front Panel of the DEM-410X
