MP7500 Router Installation Manual Version 1.0
Temperature and Humidity
To ensure the service quality and life of MP7500 series routers, it is
recommended to maintain a certain temperature and humidity in the
computer lab. If the humidity in the computer lab is 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 easily, too. If the relative humidity is too low,
insulation pads shrink, which causes the fastened screws loose.
Meanwhile, in dry environment, static electricity appears easily, which
harms the circuits on the router.
If the temperature is too high, the reliability of the router reduces greatly.
The long-time high temperature affects the life and speeds up the aging of
insulation materials.
The recommended temperature and humidity in computer room:

•
Measuring points of the working temperature and humidity of MP7500
in the computer 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.
•
The short-term working condition means less than 48h continuously
and less than 15 days for the annual total.
•
Extreme adverse working environment means the environment
temperature and humidity when the air-conditioning system in the
computer room fails. Each time the normal work should be recovered
within less than 5h.
Dust-free Environment
Dust is harmful for MP7500 operation. Dust causes static absorption,
which makes the poor contact of metal pieces. Static absorption appears
especially when the temperature and humidity are lower, which affects the
device life and causes communication fault.
