Ventilation
•
Ensure a minimum clearance of 100 mm (3.94 in)
around the air inlet and outlet vents of the chassis.
•
If you install the firewall in a standard 19-inch rack,
ensure a distance of 1U (44.45 mm, or 1.75 in)
between the chassis and other devices.
•
A good ventilation system is available at the
installation site.

ESD prevention
•
The equipment, workbench, and rack are reliably
grounded.
•
The equipment room is dust-proof.
•
The humidity and temperature are at an acceptable
level.
•
Wear an ESD wrist strap and make sure it makes
good skin contact and is reliably grounded when
installing removable components.
•
Put the removed interface modules away on an ESD
workbench, with the PCB upward, or put them in ESD
bags for future use.
•
Touch only the edges, instead of electronic
components when observing or moving a removed
interface module.
EMI prevention
•
Take effective measures to protect the power system
from the power grid system.
