Installation site requirements

The following tables provide information about temperature and humidity, cleanness, and air quality

requirements.

CAUTION:

If condensation appears on the router when you move it to a high-temperature environment, dry the

router before powering it on to avoid short circuits.

To ensure normal operation of the router, make sure the room temperature meets the requirements

described in Table 2.

Operating temperature

Long term: 0°C to 45°C (32°F to 113°F)

Short term: –10°C to +55°C (14°F to 131°F) (no more than 96 hours of

continuous operation in less than 15 days in one year)

Storage temperature –40°C to +70°C (–40°F to +158°F)

Maintain appropriate humidity in your equipment room, as described in Table 3.

Lasting high relative humidity tends to cause poor insulation, increased electricity consumption,

mechanical property change of materials, and corrosion of metal parts. Lasting low relative humidity

is likely to result in loose screws due to washer contraction, and even ESD, which causes the circuits to

fail.
