• 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
CAUTION:
Make sure the resistance reading between human body and the ground is in the range of 1 to 10 megohm
(Mohm).
To prevent electrostatic discharge (ESD), note the following guidelines:
• Make sure the router and the floor are well grounded.
• Take dust-proof measures for the equipment room.
• Maintain the humidity and temperature in the acceptable range.
• Always wear an ESD 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.
• Touch only the edges, instead of electronic components when observing or moving a removed
memory module, CF card, or HIM/MIM.
To attach the ESD wrist strap:
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to keep good contact with the skin.
3. Insert the ESD wrist strap into the specially designed hole on the router chassis or attach it to the
grounding screw of the chassis with the alligator clips.
4. Make sure the rack is well grounded.
