2.3 Examining the installation site
The QX-S5500 Series switches must be used indoors.
Mount your switch in a rack or on a workbench and make sure:
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
The rack or workbench has a good ventilation system.
Identify the hot aisle and cold aisle at the installation site, and make sure ambient air
flows into the switch from the cold aisle and exhausts to the hot aisle.
Identify the airflow designs of neighboring devices, and prevent hot air flowing out of
the bottom device from entering the top device.
The rack is sturdy enough to support the switch and its accessories.
The rack is well earthed.
To ensure normal operation and long service life of your switch, install it in an environment
that meets the requirements described in the following subsections.
2.4 Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
Lasting high relative humidity can cause poor insulation, electricity creepage,
mechanical property change of materials, and metal corrosion.
Lasting low relative humidity can cause washer contraction and ESD and bring
problems including loose captive screws and circuit failure.
High temperature can accelerate the aging of insulation materials and significantly
lower the reliability and lifespan of the switch.
For the temperature and humidity requirements of different switch models, see "
