There is a minimum clearance of 100 mm (3.94 in)
around the inlet and outlet air vents for heat
dissipation of the firewall chassis.
A good ventilation system is available at the
installation site.
Operating:
Without hard disks: 0°C to 45°C (32°F to 113°F)
With hard disks: 5°C to 40°C (41°F to 104°F)
Storage: –40°C to +70°C (–40°F to +158°F)
Operating:
Without hard disks: 5% RH to 95% RH,
noncondensing
With hard disks: 10% RH to 90% RH,
noncondensing
Storage: 5% RH to 95% RH, noncondensing
Dust concentration ≤ 3 × 10
No dust on desk within three days
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 FRUs.
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.
Take effective measures to protect the power system
from the power grid system.
Separate the protection ground of the firewall from
the grounding device or lightning protection
grounding device as far as possible.
Keep the firewall far away from radio stations, radar
and high-frequency devices working in high current.
Use electromagnetic shielding when necessary.
The grounding cable of the chassis is reliably
grounded.
The grounding terminal of the AC power receptacle is
reliably grounded.
(Optional.) A power lightning arrester is installed.
Equip a UPS.
Locate the power switch in the equipment room. In
case of emergency during operation, switch off the
power switch.
