To ensure good ventilation, follow these guidelines:
•
Maintain a minimum clearance of 100 mm (3.94 in) around the air inlet and outlet vents.
•
Make sure the installation site has a good ventilation system.
ESD prevention
WARNING!
Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range
of 1 to 10 megohm (Mohm) between a human body and the ground.
To prevent electrostatic discharge (ESD), follow these guidelines:
•
Make sure the device is reliably grounded.
•
Take dust-proof measures for the equipment room.
•
Maintain the humidity and temperature in the equipment room in the acceptable range.
•
Always wear an ESD wrist strap and ESD garment when touching a circuit board or transceiver
module.
The device does not provide an ESD wrist strap, prepare it yourself.
•
Place the removed interface module on an antistatic workbench with the circuit board upward,
or put it in an antistatic bag.
•
Touch only the edges instead of electronic components on the circuit board when you observe
or move a removed 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 maintain good contact with the skin.
3.
Secure the wrist strap lock and the alligator clip lock together.
4.
Attach the alligator clip to the grounding screw on the device.
