Safety Environment
Consider measures to deal with disasters (such as fires, floods and earthquakes) and to ensure the
safety of the staff.
Regularly clean the room or rooms where the switching equipment resides.
Do not spray any insecticides directly on the equipment (insecticides can adversely affect the switch-
ing equipment).
Air Conditioning Facilities
The system and the air conditioning system must be installed separately and have separate power
sources.
To prevent an electromagnetic arc from causing noise, attach a surge-limiting capacitor and resistor
on the air conditioner’s electromagnetic switch’s coil.
It might be necessary to adjust the ventilation so the air conditioning is equally effective throughout
the equipment room.
Do not place the system in a location where condensation might fall from an air conditioner or a duct.
Do not place the system in a location where hot and humid air is exhausted, as this might damage the
system.
The grounding system must protect the system, MDF, main power source, PCPro, printer, modems,
etc. from damage caused by lightning strikes and electrical surges.
All the grounding conductors must have a resistance of less than one Ω to bring a zerovoltage refer-
ence to the system components.
To achieve this, the following ground conductors must connect to the Primary Ground Bar:
• The Earth Ground (E) from the Rectifier
• The Frame Ground (FE) from the system
• The Power Ground (PE) from the system, through the Rectifier
• The Frame Ground (FE) from the MDF
• The AC service outlets, with plug outlets, for the PCPro, printer, modems and any measurement
devices, such as a protocol analyzer.
Electromagnetic Interference
When installing an additional device in the vicinity of the system, observe the installation and operat-
ing instructions for the device.
Otherwise, EMI noise from the device may cause a malfunction of the system.
Disposables and Periodic-replacement Parts
Many parts, such as batteries, backup batteries, fuses and displays need to be replaced on a periodic
basis. In the event of sudden traffic, a part that is past due for replacement might lead to a system
failure and damage to the system.
A service contract with the dealer or its service technician to monitor the replacement cycles and to
supply the replacement parts and the necessary disposables is recommended.
