H3C SecPath V1000-A Security Gateway
2.1.4 Electromagnetic Environment
All interference sources, wherever they are from, impact the security gateway
negatively in the conducted emission patterns of capacitance coupling, inductance
coupling, electromagnetic wave radiation, and common impedance (including the
grounding system) coupling. To resist the interference, make sure to:
Take effective measures against the interference caused by the power supply
grid.
Use an earthing system or lightning protection grounding different from that for the
power supply equipment and keep them as far as possible.
Keep the device far from strong the power radio launchers, radar launchers, and
high frequency and high-current equipment.
Use electromagnetic shielding when necessary.
2.1.5 Lightning Protection
Although the security gateway is designed to be lightning resistant, your device can get
damaged when excessive lightning is present. To protect your device against lightning,
Ensure the chassis is connected to the earth ground.
Ensure the earth point of the power socket is well connected to the earth ground.
Add a lightning arrester onto the front end of the power input to better protect the
power supply from lightning strikes.
2.1.6 Mounting Rack
When installing the device in a rack, make sure that:
There is adequate clearance between the air inlet/exhaust vents and the rack for
ventilation.
The rack has a good ventilation system.
The rack is firm enough to support the device and its accessories.
The rack is well earthed.
2.2 Safety Precautions
Be sure that you observe all safety precautions when you install your security gateway
and pay adequate attention to the following icons:
Warning appears in operation procedures that, if performed incorrectly, might
cause bodily injury to the operators or damage the device.
Caution means care should be taken in these operations during installation and
use. Improper operations may result in abnormal running of the device.
