Ruijie RG-S6120 Series Switches Hardware Installation and Reference Guide
On the other hand, in an environment with low relative humidity, the insulating strip may dry and shrink, and static
electricity may occur easily and endanger the circuit on the device.
In an environment with high temperature, the equipment is subjected to even greater harm, as its performance
may degrade significantly and its service life may be shortened at high temperature for long that expedites the
aging process.
Temperature and humidity requirements of the RG-S6120 series switch:
Model
Working Temperature
Working Humidity
RG-S6120-48XS8CQ
0°C to 45°C (32°F to 113°F)
10% to 90% non-condensing
RG-S6120-20XS4VS2QXS
0°C to 50°C (32°F to 113°F)
10% to 90% non-condensing
RG-S6120-24XMG4XS4VS-UP-E
0°C to 45°C (32°F to 113°F)
10% to 90% non-condensing
The temperature and humidity are measured at the point that is 1.5 m above the floor and 0.4 m before the device
when there is no protective plate in front or at the back of the device rack.
2.2.4 Cleanness Requirements
Dust poses the top threat to the running of the device. The indoor dust falling on the device may be adhered by the
static electricity, causing poor contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the service life of the device, but also causing communication faults. The
following table shows the requirements for the dust content and granularity in the equipment room.

Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict requirements; as such
poisonous substances may accelerate the corrosion of the metal and the aging of some parts. The equipment room
should be protected from the intrusion of harmful gases (for example, SO

S, NO

and Cl

), whose requirements are

The

refers to the average limit of harmful gas in one week. The
Maximum
value is the upper limit of the
harmful gas in one week, and maximum value can last for up to 30 minutes every day.
2.2.5 System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-S6120 series switch. It is the key to
prevent lightning stroke and resist interference. Please carefully check the grounding conditions on the installation site
according to the grounding requirements, and perform grounding properly as needed.
