CHAPTER 2 INSTALLATION DESIGN
1. GENERAL
This chapter provides information pertaining to installation design and preparation of the required installation
materials. The following topics are discussed:
• Environmental Requirements
• Floor Space
• Floor Load Requirements
• Equipment Room Requirements
• Power Supply Requirements
• MDF Requirements
• Installation Tools
• System Accommodation
• Installation Cables
2. ENVIRONMENTAL REQUIREMENTS
The PBX is sensitive to the same rises in temperature and humidity as a computer. Air conditioning may be re-
quired, depending on the installation environment. The following paragraphs address the following environ-
mental conditions.
• Temperature and Humidity
• Heat Generation from Switching Equipment
2.1 Temperature And Humidity
Table 2-1 shows the environmental conditions required in the switching equipment room.
If the switching system is operated in an environment that does not meet these specifications, the reliability of
the switching equipment may be impaired. Improper operating conditions can cause circuit boards, etc., to de-
teriorate. Therefore, to enable the equipment to operate for the extent of its expected lifetime, careful consider-
ation must be given to the location of the equipment, and to proper ventilation and air conditioning.
If no equipment is provided to remove the heat generated by the system, or if the temperature or humidity fluc-
tuates repeatedly, the system’s electronic parts can be adversely affected. Such conditions will promote corro-
sion of metal parts and deterioration of insulation, thereby lowering the overall reliability of the system.
