Chapter 2 Preparation for Installation
2-3
2.1.4 Electromagnetic Environment
All interference sources, wherever they are from, impact the firewall 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:
z
Take effective measures against the interference caused by the power supply grid.
z
Use a grounding system or lightning protection grounding different from that for the
power supply equipment and keep them as far as possible.
z
Keep the device far from strong the power radio launchers, radar launchers, and
high frequency and high-current equipment.
z
Use electromagnetic shielding when necessary.
2.1.5 Lightning Protection
Although the H3C SecPath Series Firewall is designed to be lightning resistant, your
device can get damaged when excessive lightning is present. To protect your device
against lightning,
z
Ensure the chassis is connected to the earth ground.
z
Ensure the earth point of the power socket is well connected to the earth ground.
z
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:
z
There is adequate clearance between the air inlet/exhaust vents and the rack for
ventilation.
z
The rack has a good ventilation system.
z
The rack is firm enough to support the device and its accessories.
z
The rack is well earthed.
