Temperature
Storage environment temperature
-20°C–70°C
Work condition
0°C–45°C
If the temperature is too high, the reliability of the router reduces greatly. The
long-time high temperature affects the router life and speeds up the aging of
insulation materials.
When the router enters the high-temperature environment from the low-temperature
environment and if there is condensed water on the router, be sure to take some
measures (such as drying and airing) before the router is powered on, so as to
prevent the internal components of the router from short-circuit and being burned.
C1.2 Humidity Requirement
To ensure that the router can work normally, it is recommended to maintain certain
humidity in the equipment room. The work humidity requirement is shown in the
following table.
Appendix Table C-2 Work humidity requirements
Description
Humidity
Work condition
5%–85%/RH, no-condensing
Storage Condition
0%–95%/RH, no-condensing
Measuring points of the working temperature and humidity of MP1900X router in the
equipment room mean the values measured from the floor above 1.5 m and 0.4 m
from the front of the rack when there are no protection boards.
If the humidity in the equipment room is too high for long time, it causes the poor
insulation and even electricity leak of insulation materials easily. Sometimes, the
mechanical performances of materials change and the metal parts are corroded
