Chapter 2 Hardware Installation
2.1 Installation Notice
To ensure the proper operation for S5750E-16(28)(52)F(C)(X)(-P)-SI(R2.0) 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 5% 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 S5750E-16(28)(52)F(C)(X)(-P)-SI(R2.0)
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:
Max Diameter (µm) 0.5 1 3 5
Max Density
(particles/m³) 1.4×105 7×105 2.4×105 1.3×105
Table 2-1 Environmental Requirements: Dust

S5750E-16(28)(52)F(C)(X)(-P)-SI(R2.0) Chapter 2 Hardware Installation
2-2
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, NH3 and Cl2, etc. The table below details the
threshold value.
Gas Average (mg/m³) Max (mg/m³)
SO2 0.2 1.5
H2S 0.006 0.03
NO2 0.04 0.15
NH3 0.05 0.15
Cl2 0.01 0.3
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.
The recommended temperature and humidity are shown below:
Temperature: Relative humidity
Long term condition
Short term condition
Long term condition
Short term
condition
15 ~ 30°C 0 ~ 50°C 40 ~ 65% 5 ~ 95%
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

S5750E-16(28)(52)F(C)(X)(-P)-SI(R2.0) Chapter 2 Hardware Installation
2-3
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;
 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
