Installation Site Requirements; Temperature And Humidity - Ruijie RG-PF2920 Series Hardware Installation And Reference Manual

Hardware Installation and Reference Guide
2.1.6 Storage
To ensure proper working of the device, store the device in an environment based on the storage temperature or
humidity requirements in specifications.
Caution
If the device has been powered off for more than 18 months, power on the device and run it for consecutive 24
hours to activate the device.

Installation Site Requirements

The installation site must meet the following requirements to ensure normal operation and prolonged service life
of the device.
2.2.1 Ventilation
The RG-PF2920-16GT2XS/RG-PF2920-8GT2MG2XS uses natural heat dissipation, and the heat is primarily
dissipated through the housing. When the device works at a temperature above 35° C (95° F), the surface
temperature of the device can rise significantly. Refrain from direct contact with the device using bare hands.
Moreover, it is crucial to install the device in a restricted-access area that offers sufficient ventilation, only
accessible to authorized personnel such as maintenance staff, professionals, or relevant technical personnel.
Avoid placing the device on a desktop or inside an enclosed cabinet.
2.2.2

Temperature and Humidity

To ensure the normal operation and service life of the switch, maintain an appropriate temperature and humidity
in the environment where the switch is used.

Prolonged exposure of the switch to a high relative humidity environment can result in compromised
insulation of the insulating material, potentially leading to electrical leakage. Additionally, the mechanical
properties of materials may undergo alterations, and there is an increased risk of corrosion for metal
components.

Extended storage of the switch in a low relative humidity environment can result in the shrinkage of insulating
strips, leading to the loosening of fastening screws. Additionally, the occurrence of static electricity becomes
more likely, which poses a risk of damaging internal circuits of the switch.

Extended exposure of the switch to a high ambient temperature environment can result in amplified damage.
The elevated temperature accelerates the aging process of insulating materials, significantly diminishing the
performance and reliability of the switch while severely impacting its service life.
