Installation site
Ventilation
• There is a minimum clearance of 10 cm (3.94 in)
around the inlet and outlet vents for heat
dissipation of the router chassis.
• A good ventilation system is available at the
installation site.
Temperature 0°C to 45°C (32°F to 113°F).
Relative humidity 5% to 90% (noncondensing).
Cleanness
• Dust concentration ≤ 3 × 10 4 particles/m 3 .
• No visible dust on desk within three days.
ESD prevention
• The equipment and floor are correctly grounded.
• The equipment room is dust-proof.
• The humidity and temperature are at acceptable
levels, respectively.
• Wear an ESD wrist strap and uniform when
touching a circuit board.
• Place the removed memory module, CF card, or
interface module on an antistatic workbench, with
the face upward, or put it into an antistatic bag.
• Touch only the edges, instead of electronic
components when observing or moving a removed
memory module, CF card, or interface module.
EMI prevention
• Take effective measures to protect the power
system from the power grid system.
• Separate the protection ground of the router from
the grounding device or lightning protection
grounding device as far as possible.
