Chapter 2 Hardware Installation
2.1 Installation Notice
To ensure the proper operation for DG-GS4900SE series and your physical security,
please read carefully the following installation guide.
2.1.1 Environmental Requirements
The switch must be installed in a clean area. Otherwise, the switch may be damaged
by electrostatic adherence.
Maintain the temperature within 0 to 50 °C and the humidity within 10% to 95%,
non-condensing.
The switch must be put in a dry and cool place. Leave sufficient spacing around the
switch for good air circulation.
The switch must work in the right range of power input (AC power: 90 ~ 264V (50Hz),
DC power: -40 ~ -60V)
The RPS input of the switch must be in the range of +11.5 ~ +13VDC.
The switch must be well grounded in order to avoid ESD damage and physical injury
of people.
The switch should avoid the sunlight perpendicular incidence. Keep the switch away
from heat sources and strong electromagnetic interference sources.
The switch must be mounted to a standard 19’’ rack or placed on a clean level
desktop.
2.1.1.1 Dust and Particles
Dust is harmful to the safe operation of DG-GS4900SE series. Dust can lead to
electrostatic adherence, especially likely under low relative humidity, causing poor contact
of metal connectors or contacts. Electrostatic adherence will result in not only reduced
product lifespan, but also increased chance of communication failures. The recommended
value for dust content and particle diameter in the site is shown below:

Table 2- 1 Environmental Requirements: Dust
In addition, salt, acid and sulfide in the air are also harmful to the switch. Such
harmful gases will aggravate metal corrosion and the aging of some parts. The site should
avoid harmful gases, such as SO2, H2S, NO2, NH3and Cl2, etc. The table below details the
threshold value.

Table 2- 2 Environmental Requirements: Particles
2.1.1.2 Temperature and Humidity
Although the switch is designed to use 4 fans, the site should still maintain a desirable
temperature and humidity. High-humidity conditions can cause electrical resistance
degradation or even electric leakage, degradation of mechanical properties and corrosion
of internal components. Extreme low relative humidity may cause the insulation spacer to
contract, making the fastening screw insecure. Furthermore, in dry environments, static
electricity is liable to be produced and cause harm to internal circuits. Temperature
extremes can cause reduced reliability and premature aging of insulation materials, thus
reducing the switch’s working lifespan. In the hot summer, it is recommended to use
air-conditioners to cool down the site. And the cold winter, it is recommenced to use
heaters.

Table 2- 3 Environmental Requirements: Temperature and Humidity
Caution!
A sample of ambient temperature and humidity should be taken at 1.5m above the
floor and 0.4m in front of the switch rack, with no protective panel covering the front and
rear of the rack. Short term working conditions refer to a maximum of 48 hours of
continued operation and an annual cumulative total of less than 15 days. Formidable
operation conditions refers to the ambient temperature and relative humidity value that
may occur during an air-conditioning system failure, and normal operation conditions
should be recovered within 5 hours.
2.1.1.3 Power Supply
Before powering on the power supply, please check the power input to ensure proper
grounding of the power supply system. The input source for the switch should be reliable
and secure; a voltage adaptor can be used if necessary. The building’s circuit protection
system should include in the circuit a fuse or circuit-breaker of no greater than 240 V, 10 A.
It is recommended to use a UPS for more reliable power supplying. .
Caution!
Improper power supply system grounding, extreme fluctuation of the input power, and
transients (or spikes) can result in larger error rate, or even hardware damage!
2.1.1.4 Preventing Electrostatic Discharge Damage
Static electric discharges can cause damage to internal circuits, even the entire
switch. Follow these guidelines for avoiding ESD damage:
Ensure proper earth grounding of the device;

DG-GS4900SE Series Installation Guide
16
Perform regular cleaning to reduce dust;
Maintain proper temperature and humidity;
Always wear an ESD wrist strap and antistatic uniform when in contact with circuit
boards.
2.1.1.5 Anti-interference
All sources of interference, whether from the device/system itself or the outside
environment, will affect operations in various ways, such as capacitive coupling, inductive
coupling, electromagnetic radiation, common impedance (including the grounding system)
and cables/lines (power cables, signal lines, and output lines). The following should be
noted:
Precautions should be taken to prevent power source interruptions;
Provide the system with a dedicated grounding, rather than sharing the grounding
with the electronic equipment or lightning protection devices;
Keep away from high power radio transmitters, radar transmitters, and high frequency
strong circuit devices;
Provide electromagnetic shielding if necessary.
2.1.1.6 Rack Configuration
The dimensions of the DG-GS4900SE series is designed to be mounted on a
standard 19’’ rack, please ensure good ventilation for the rack.
Every device in the rack will generate heat during operation, therefore vent and fans
must be provided for an enclosed rack, and devices should not be stacked closely.
When mounting devices in an open rack, care should be taken to prevent the rack
frame from obstructing the switch ventilation openings. Be sure to check the
positioning of the switch after installation to avoid the aforementioned.
Caution！
If a standard 19’’ rack is not available, the DG-GS4900SE series can be placed on a
clean level desktop, leave a clearance of 100mm around the switch for ventilation, and do
not place anything on top of the switch.

DG-GS4900SE Series Installation Guide

2.1.2 Installation Notice
Read through the installation instruction carefully before operating on the system.
Make sure the installation materials and tools are prepared. And make sure the
installation site is well prepared.
During the installation, users must use the brackets and screws provided in the
accessory kit. Users should use the proper tools to perform the installation. Users
should always wear antistatic uniform and ESD wrist straps. Users should use
standard cables and connecters.
After the installation, users should clean the site. Before powering on the switch,
users should ensure the switch is well grounded. Users should maintain the switch
regularly to extend the lifespan of the switch.
2.1.3 Classs A Statement
Class A ITE is a category of all other ITE which satisfies the class A ITE limits but not
the class B ITE limits. The following warning shall be included in the instructions for use:
Warning
This is class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
2.1.4 Security Warnings
When using SFP transceiver, do not stare directly at the fiber bore when the switch is
in operation. Otherwise the laser may hurt your eyes.
Do not attempt to conduct the operations which can damage the switch or which can
cause physical injury.
Do not install, move or disclose the switch and its modules when the switch is in
operation.
Do not open the switch shell.

DG-GS4900SE Series Installation Guide
18
Do not drop metals into the switch. It can cause short-circuit.
Do not touch the power plug and power socket.
Do not place the tinder near the switch.
Do not configure the switch alone in a dangerous situation,
Use standard power sockets which have overload and leakage protection.
Inspect and maintain the site and the switch regularly.
Have the emergence power switch on the site. In case of emergence, switch off the
power immediately.
Caution!
Potential risk include: Electric leakage, Power supply arcing, Power line breakage,
Imperfect earth, Overload circuit and Electrical short circuit.If electric shock, fire, electrical
short circuit occurs, please cut off the electricity supply and alarm rapidly. Rescue the
injured person in the contingency under inherently safe, give the injured person proper
first aid treatment according to the injury state, and seek help from the Medical
Emergency using various ways.
