To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.
Grounding
Using a good grounding system to protect your router against lightning shocks, interferences, and
ESD is essential to the operating reliability of your router. For more information about grounding the
router, see "Grounding the router."
Make sure the resistance between the chassis and the ground is less than 1 ohm.
Power
Perform the following tasks to meet the power requirements:
1.
Calculate the system power consumption.
The system power consumption varies by card type and density. For more information about
system power consumption calculation, see
H3C CR16000-F Router Series Hardware
Information and Specifications
.
2.
Select power supplies and identity the number of power supplies.
The total maximum output power of all power supplies must be higher than the system power
consumption. For more information about available power supplies, see
H3C CR16000-F
Router Series Hardware Information and Specifications
.
3.
Verify that the power system at the installation site meets the requirements of the power
supplies, including the input method and rated input voltage.
Cooling
For heat dissipation, make sure the following requirements are met:
•
A minimum clearance of 10 cm (3.94 in) is reserved around the inlet and outlet air vents.
•
The rack for the router has a good cooling system.
•
The installation site has a good cooling system.
