Cooling system
The H3C SR6602 router adopts left to right airflow for heat dissipation.
Figure 3 SR6602 airflow
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 the floor are well grounded.
Take dust-proof measures for the equipment room.
Maintain the humidity and temperature at a proper level.
Always wear an ESD-preventive wrist strap when touching a circuit board or transceiver module.
Place the removed memory module, CF card, or HIM/MIM on an antistatic workbench, with the
face upward, or put it into an antistatic bag.
