H3C SecPath V1000-A Security Gateway
Chapter 2 Preparation for Installation
2.1 Site Requirements
The security gateway must be used indoors. To guarantee the normal operation and
long service life of your security gateway, install it in an environment that can meet the
requirements in the following subsections.
2.1.1 Temperature/Humidity
The equipment room must maintain adequate temperature and humidity. Long-lasting
high humidity is prone to cause bad insulation and even electricity creepage.
Sometimes the mechanical performance changes of materials, the rustiness and
corrosion of some metal parts are also likely to occur. If the relative humidity is too low,
the captive screws can become loose due to insulation washer contraction. Meanwhile,
the static is likely produced in the dry environments, jeopardizing the CMOS circuit of
the product. The higher the temperature is, the greater the damage to your device.
Long-lasting high temperature can speed up the aging of the insulation materials,
greatly lower the device reliability, and hence significantly shorten its service life.
The following table lists the temperature and humidity requirements.

2.1.2 Cleanness
Dust is a hazard to the operating safety of your device. The dust accumulated on the
chassis can cause electrostatic adsorption, one of the sources that cause the poor
contact of connectors or metal contact points. This not only shortens the service life of
your device but also causes communications failures. When the indoor relative
humidity is low, electrostatic adsorption is more likely to happen.
The equipment room must be free of explosion hazards and the electrical and magnetic
conductible dust as well. The contents of the dust must be limited as shown in the
following table:
