Site Requirements; Temperature And Humidity Requirements - Accton Technology ES4710BD User Manual

Notice
! Watch out for potential dangers, e.g. wet floors, ungrounded power lines, and worn power lines.
! Have an emergency switch installed inside the workshop, so that power can be cut off promptly
should an accident occur.
! Do not work alone if potential dangers are present.
! On the event of an accident, take the following measures:
1. Power down the system
2. Make emergency calls if required
3. Determine whether the victim requires immediate treatment and take appropriate action
4. If possible, send someone for medical help; otherwise, consider the damage and seek help

2.1.1 Site Requirements

The ES4710BD must be used indoors, and have the following requirements:
Ambient temperature: 0 ~ 40°C
Humidity: 10% ~ 90%, non-condensing
The ES4710BD is equipped with a fan assembly for providing the switch with an appropriate level
of cooling; you can place the switch on a workbench or rack. Ensure the following:
The rack or workbench should be well ventilated. For sufficient air circulation, it is
recommended to mount the switch on a 19" standard rack with sufficient spacing. Air
conditioning is recommended in areas with high temperatures in the summer.
To cool the internal circuits, the switch comes with internal fan assemblies. To maintain
proper air circulation through the switch chassis, we recommend that you maintain a
minimum 100mm separation between the chassis air intake or the chassis air exhaust and
any walls. Make sure that all air intakes and exhausts on the system remain unobstructed. Do
not stack heavy items on the switch.
Make sure the rack or workbench are strong enough to support the weight of a fully
configured switch.
Make sure the rack or workbench is well grounded; if the workbench is not grounded, it
should be placed near a grounding conductor to provide easy ground connection for the
switch.

2.1.2 Temperature and Humidity Requirements

To maximize the switch's performance and lifespan, the site should 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. The recommended temperature
and humidity are shown below:
