NH-3730-24F Hardware Installation Manual
shutdowns or unusually high errors with your existing equipment, this precautions might
help you isolate the cause of failures and prevent future problems.
2.2.2 Preventive site configuration
The following precautions will help you plan an acceptable operating environment for
you switch and help you avoid environmentally-cauesd equipment failures:
z
Ensure that the room in which you operate your system has adequate air
circulation. Electrical equipment generates heat. Ambient air temperature might
not be able to cool equipment to acceptable operating temperatures without
adequate circulation.
z
Always follow the EDS-prevention procedures to avoid damage to equipment.
Damage from static discharge can cause immediate or intermittent equipment
failure.
z
The chaissis is designed to allow cooling air to flow effectively inside it .An open
chassis allows allows air leaks, which might interrupt and redirect the flow of
cooling air from internal components.
2.2.3 Configuring Equipment rack
The following information will help you plan an acceptable equipment rack
configuration.
z
The equipment in the rack will heat when working. So enclosed racks must have
adequate ventilation.The equipment should not be put too close to each other to
ensure the racks are not overheat.
z
When mounting a chassis in an open rack ensure that the rack frame does not
lock the intake or or the exhaust ports.So check the position of the chassis when it
is seated all the way into the rack.
z
Ensure that you provide adequate ventilation for equipment at the bottom of rack.
z
Baffles can help to isolate exhaust air from intake air, which also helps to draw
cooling air through the chassis .The best placement of the chassis on the airflaw in
the rack, which and be found by experimenting with different arrangement.
2.2.4 Power supply condition
Check the power at you site to ensure that you are receiving "clean" power. Install a
power conditioner if necessary. Ensure that a fuse or circuit breaker no larger than
240V,10A interminal is used on the phase conductors.
Warning
：
If the power system does not connect to the earth properly , the variables of input power is big or exist
excess pulse, it will add error ratio of communication equipment , even to damage the hardware system.
