2.1 Installation Notice

To ensure the proper operation for DCRS-5960 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 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 DCRS-5960 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

harmful gases will aggravate metal corrosion and the aging of some parts. The site should

avoid harmful gases, such as SO

2

, 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

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% 10 ~ 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

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

DCRS-5960 Series Installation Guide Chapter 2 Hardware Installation

2-3

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.
