To ensure good ventilation, the following requirements must be met:
• The air inlet and outlet vents are not blocked, and leave at least 10 cm (3.94 in) of clearance.
• The installation site has a good cooling system.
ESD prevention
To prevent electrostatic discharge (ESD), follow these guidelines:
• Make sure 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 wrist strap and ESD-preventive cloth when touching a circuit board or
transceiver module.
An MSR3000 router does not supply an ESD-preventive wrist wrap. Prepare an ESD-preventive
wrist wrap yourself.
• Place the removed memory module, CF card, or interface module on an antistatic workbench, with
the face upward, or put it into an antistatic bag.
• Touch only the edges, instead of electronic components when you observe or move a removed
memory module, CF card, or interface module.
To attach an 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-preventive plug into the ESD-preventive socket.
4. Make sure the rack is well grounded.
CAUTION:
Check the resistance of the ESD wrist strap for safety. The resistance readin
g
should be in the ran
g
e of 1
to 10 megohm (Mohm) between human body and the ground.
