To prevent overheating:

• Provide adequate clearance for air flow, including at least 10 cm (3.94 in) ventilation space around

the router's air intake and outlet vents.

• Make sure the site has an adequate cooling system.

ESD prevention

To prevent the electronic components from being damaged by ESD, follow these guidelines:

• The equipment and floor are correctly grounded.

• The equipment room is dust-controlled.

• Wear an ESD wrist strap when inspecting or handling a circuit board.

To attach an ESD wrist strap:

1. Wear the wrist strap on your wrist.

No wrist strap is supplied with the router. Prepare it yourself.

2. Lock the wrist strap tight around your wrist to keep good contact with the skin.

3. Insert the ESD plug into the ESD socket in the chassis.
