•
Make sure there is enough space (greater than 10 cm (3.94 in)) around the air intake and outlet
vents on the router for good ventilation.
•
Make sure the installation site has a good cooling system.
ESD prevention
To prevent electrostatic discharge (ESD), note the following guidelines:
•
Make sure that the router and rack are well grounded.
•
An anti-static floor is installed and well grounded.
•
Maintain the humidity and temperature at a proper level in the equipment room. For more
information, see “
•
Always wear an ESD-preventive wrist strap and ESD-preventive cloth when touching a circuit board,
interface module, or transceiver module.
•
Place the removed memory module, CF card, FIP, HIM, or MIM on an antistatic workbench, with the
face upward, or put it into an antistatic bag.
