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 operating temperature and humidity
ranges. For more information about the acceptable operating temperature and humidity ranges, refer to the
Physical and Environmental section.
• 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
included rubber feet 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 markings are usually found in each corner on the bottom of
the device. The rubber feet cushion the Switch, protecting the casing from scratches and preventing it from scratching
other surfaces.
Figure 3-1 Attaching rubber feet to the Switch
Install the Switch on a sturdy, level surface that can support the weight of the 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, sides, and rear of the Switch for ventilation.

To connect AC power to the Switch, plug one end of the AC power cord into the AC power socket of the Switch and
the other end of the AC power cord into the local AC power source outlet. There is no power switch/button on the
Switch. The system will power on automatically.
After the system is powered on, the Power LED will blink green to indicate that the system is booting up. In the event
of a power failure, just as a precaution, unplug the power cord from the Switch. After the power returned, plug the
power cord back into the power socket of the Switch.
Installing the AC Power Cord Retainer
To prevent accidental removal of the AC power cord, it is recommended to install the AC Power Cord Retainer Set
together with the AC power cord. The AC Power Cord Retainer Set is included in the package contents.
With the rough side facing down, insert the tie wrap into the hole below the power socket.

Connecting PoH to the Switch
When AC power is not available, the Switch can be powered using PoH (Power over HDBaseT) through the MGMT
port. Adhering to HDBaseT, up to 90 Watts of DC power can be provided to the Switch from Power Sourcing
Equipment (PSE) over a Category 5e/6a LAN cable.
When AC power is used, the PoH connection to the MGMT port can be used as a backup power supply to the Switch.
When AC power fails, the PoH DC power through the MGMT port will keep the Switch powered on until AC power
returns.
NOTE: Only the DGS-1520-28 and DGS-1520-52 feature a MGMT PoH-capable port on the back panel.
NOTE: The D-Link DPS-520 Managed PSE is the recommended DC power sourcing equipment for the
Switch.
CAUTION: Do not connect the RPS to AC power before the PoH cable is connected. This might damage
the internal power supply.
ATTENTION: Ne branchez pas le RPS sur le courant alternatif avant que le câble PoH ne soit branché.
Cela pourrait endommager l'alimentation électrique interne.
The following diagram illustrates how to connect the powered Ethernet cable from the PSE (at the bottom) to the
MGMT port on the Switch (at the top).
Figure 3-10 Connecting the PSE to the MGMT Port
CAUTION: Leave at least 15 cm (6 inches) of space at the rear of the Switch when an RPS is installed
to prevent cable damage.
ATTENTION: Laissez un espace d’au moins 15 cm (6 pouces) à l'arrière du commutateur lorsqu'un RPS
est installé pour éviter d'endommager les câbles.
DGS-1520 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide

Installing the Redundant Power Supply (RPS)
An RPS is an external unit, enclosed in solid metal casing, with sockets to connect AC or DC-powered sources at one
end and to connect to a switch’s internal power supply on the other end. The RPS provides a low-cost, simple solution
to the problem of an inadvertent failure of the internal power supply of an Ethernet switch, which can result in the
shutdown of that switch, the devices attached to its ports, or an entire network.
Connecting the DPS-700 RPS to the Switch
The D-Link DPS-700 is the recommended RPS for the Switch. This RPS is designed to conform to the wattage
requirements of D-Link’s Ethernet and Gigabit switches and can be connected to the RPS port of the Switch using a
22-pin DC power cable. A standard, three-pronged AC power cable connects the RPS to the main power source.
CAUTION: Do not connect the RPS to AC power before the DC power cable is connected. This might
damage the internal power supply.
ATTENTION: Ne branchez pas le RPS sur le courant alternatif avant que le câble d'alimentation en
courant continu ne soit branché. Cela pourrait endommager l'alimentation électrique interne.
To connect the RPS to the Switch, remove the AC power cord from the AC power port of the Switch.
With a Phillips-head screwdriver, remove the RPS port cover by unscrewing the two screws that hold the RPS cover in
place.
Figure 3-11 Removing the RPS port cover
Insert one end of the 22-pin DC power cable into the RPS port on the switch and the other end into the RPS. Connect
the RPS to the main AC power source.
Figure 3-12 Connecting the DPS-700
DGS-1520 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide
19
A green LED on the front panel of the RPS will be on to indicate a successful connection. Reconnect the AC power
cord to the AC power port of the Switch. The RPS LED indicator on the front panel of the Switch will indicate that an
RPS is present and now in operation. No software configuration is required.
CAUTION: Leave at least 15 cm (6 inches) of space at the rear of the Switch when an RPS is installed
to prevent cable damage.
ATTENTION: Laissez un espace d’au moins 15 cm (6 pouces) à l'arrière du commutateur lorsqu'un RPS
est installé pour éviter d'endommager les câbles.
NOTE: Only the DGS-1520-28MP and DGS-1520-52MP feature a 22-pin RPS port on the back panel.
Always keep the RPS port cover installed when there is no RPS connected to the Switch.

Switch to End Node
Stacking the Switch
Switches in this series support stacking up to 8 switches together while being managed through one console
connection or MGMT connection on the master switch or through any of the RJ45/SFP+ ports using Telnet, the Web
UI, and SNMP. This cost-effective switch provides an affordable solution for administrators to upgrade their networks
using the stacking ports to scale and stack the Switches. This increases overall reliability, serviceability, and
availability.
Switches in the series can be physically stacked with optical fiber cables or Direct Attached Cables (DACs) with SFP+
connectors. Only the last four SFP+ ports on the Switch can be used for physical stacking.
The following stacking topologies are supported on the Switch:
• Duplex Chain - This topology stacks switches together in a chain-link format. Using this method, data transfer
is only possible in one direction. If there is a break in the chain, data transfer will be affected.
• Duplex Ring - This topology stacks switches in a ring or circle format where data can be transferred in two
directions. It is very resilient because if there is a break in the ring, data can still be transferred through the
stacking cables between switches in the stack using the alternate path.
DGS-1520 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide
21
In the following diagram, switches are stacked in the Duplex Chain topology using the two 10GBASE-T ports.
Figure 4-1 Duplex Chain Stacking Topology
DGS-1520 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide
22
In the following diagram, switches are stacked in the Duplex Ring topology using the two 10GBASE-T ports.
Figure 4-2 Duplex Ring Stacking Topology
Physical stacking needs to be enabled and can be configured to support a 2-port or 4-port stacking configuration.
SIO1 (Stacking Input/Output 1) and SIO2 are logical stacking port pairs. A logical stacking port pair must always be
connected to the same Switch in the stack. Splitting logical stacking port pairs between different Switches in the stack
might not guarantee a stable stacking connection.
The following table lists the stacking configuration with the corresponding SIO port pairs:
Configuration Switch Logical SIO1 Logical SIO2 Bandwidth

DGS-1520-52MP Port 49 and 50 Port 51 and 52 80 Gbps (full-duplex)
NOTE: SIO1 (Stacking Input/Output 1) and SIO2 are logical stacking port pairs. A logical stacking port
pair must always be connected to the same Switch in the stack. Splitting logical stacking port
pairs between different Switches in the stack might not guarantee a stable stacking connection.
Switch to Switch
The Switch can be used to connect to any other switch or hub in the network. This network topology is used when the
Switch does not have enough ports to cater for all the end nodes in the network.
There is a great deal of flexibility on how connections are made using the appropriate cabling.
• Connect a 10BASE-T or 100BASE-TX switch port to the Switch using a Category 3/4/5 UTP/STP cable.
• Connect a 1000BASE-T switch port to the Switch via a Category 5e UTP/STP cable.
• Connect a 2.5GBASE-T switch port to the Switch via a Category 5e/6 UTP/STP cable.
• Connect a 10GBASE-T switch port to the Switch via a Category 6a UTP/STP cable.
• Connect a fiber uplink switch port to the Switch's SFP+ port via a fiber optical cable.

Switch to Server
The Switch is ideal for connecting to a network backbone, server, or server farm. The RJ45 ports operate at speeds of
10/100 Mbps and 1/2.5/10 Gbps. The SFP+ ports operate at speeds of 1/10 Gbps.
Figure 4-4 Switch to a Server
Switch to End Node
An end node is a generic name for edge networking devices that will be connected to this switch. Typical examples of
end nodes are Personal Computers (PCs), Notebooks, Access Points, Print Servers, VoIP Phones and more. Each
end node should be fitted with an RJ45 networking port. Normally, end nodes will connect to this switch by using a
standard twisted-pair UTP/STP network cable. When a successful connection is established, the corresponding port
light will illuminate and blink to indicate that network activity is taking place on that port.
The diagram below displays a typical end node connected to the Switch.

SNMP-based Management
The Switch can be managed with an SNMP-compatible console program. The Switch supports Simple Network
Management Protocol (SNMP) versions 1, 2c, and 3. An SNMP agent decodes the incoming SNMP messages and
responds to requests with MIB objects stored in the database. The SNMP agent updates the MIB objects to generate
statistics and counters.
Connecting using SNMP
In SNMP versions 1 and 2c, user authentication is accomplished using community strings, which function like
passwords. The remote user SNMP application and the Switch must use the same community string. SNMP packets
from any station that were not authenticated are ignored (dropped).
The default community strings for the Switch are:
• public - Allows authorized management stations to retrieve MIB objects.
• private - Allows authorized management stations to retrieve and modify MIB objects.
SNMPv3 uses a more sophisticated authentication process that is separated into two parts. The first part is to
maintain a list of users and their attributes that are allowed to act as SNMP managers. The second part describes
what each user on that list can do as an SNMP manager.
The Switch allows groups of users to be listed and configured with a shared set of privileges. This SNMP version may
also be set for a listed group of SNMP managers. Thus, a group of SNMP managers can be created to view read-only
information or receive traps using SNMP version 1, while assigning a higher level of security to another group,
granting read/write privileges using SNMP version 3.
Using SNMP version 3 individual users or groups of SNMP managers can be allowed to perform or be restricted from
performing specific SNMP management functions. The functions that have been allowed or restricted are defined
using the Object Identifier (OID) associated with a specific MIB. An additional layer of security is available for SNMP
version 3 in that SNMP messages may be encrypted.
Traps
Traps are messages that are sent by an SNMP-enabled device to the Network Management Station (NMS) and can
be used to alert network personnel of events that occur on the Switch. These events can be as serious, like a reboot
(someone accidentally turned off the Switch), or less serious like a port status change. The Switch generates traps
and sends them to a pre-configured IP address, usually an NMS. Typical traps include trap messages for
Authentication Failure and Topology Change.
Management Information Base (MIB)
A MIB stores management and counter information. The Switch uses the standard MIB-II Management Information
Base module. Consequently, values for MIB objects can be retrieved from any SNMP-based network management
software. In addition to the standard MIB-II, the Switch also supports its own proprietary enterprise MIB as an
extended Management Information Base. The proprietary MIB may also be retrieved by specifying the MIB Object
Identifier. MIB values can be either read-only or read-write.

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 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.
ATTENTION: Le montage de systèmes sur un rack dépourvu de pieds stabilisateurs avant et latéraux
peut faire basculer le rack, pouvant causer des dommages corporels dans certains cas. Par
conséquent, installez toujours les pieds stabilisateurs avant de monter des composants sur le
rack. Après l'installation d'un système ou de composants dans un rack, ne sortez jamais plus
d'un composant à la fois hors du rack sur ses glissières. Le poids de plusieurs composants sur
les glissières en extension peut faire basculer le rack, pouvant causer de graves dommages
corporels.
• 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.
ATTENTION: Ne neutralisez jamais le conducteur de masse et ne faites jamais fonctionner le matériel
en l'absence de conducteur de masse dûment installé. Contactez l'organisme de contrôle en
électricité approprié ou un électricien qualifié si vous n'êtes pas sûr qu'un système de mise à la
masse adéquat soit disponible.
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.
ATTENTION: La carcasse du système doit être positivement reliée à la masse du cadre du rack.
N'essayez pas de mettre le système sous tension si les câbles de mise à la masse ne sont pas
raccordés. Le câblage de l'alimentation et de la mise à la masse de sécurité doit être inspecté
par un inspecteur qualifié en électricité. Un risque électrique existe si le câble de mise à la
masse de sécurité est omis ou débranché.

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):
• 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.
• When transporting a sensitive component, first place it in an antistatic container or packaging.
• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads and
an antistatic grounding strap.
