•
Keep the router far away from radio transmitting stations, radar stations, and high-frequency
devices to make sure the EMI levels do not exceed the compliant range.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Grounding
For the operating reliability of your router, follow these guidelines:
•
Use a good grounding system to protect your router against lightning shocks, interferences, and
ESD.
•
Make sure the resistance between the chassis and the ground is less than 1 ohm.
For more information about grounding the routers, see "Grounding the router."
Power
Perform the following tasks to meet the power requirements:
1. Calculate the system power consumption
The system power consumption varies by card type, density, and fan tray power consumption.
For more information about system power consumption calculation, see "Module power
consumption and total power consumption."
2. Select power supplies and determine 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 "Power supplies."
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
The airflow designs for all SR8800-F router models are the same.
For heat dissipation, make sure the following requirements are met:
•
A minimum clearance of 10 cm (3.94 in) is reserved at the inlet air vents and outlet air vents.
•
The rack for the router has a good cooling system.
•
The installation site has a good cooling system.
