Esd Prevention; Emi - H3C MSR3610-X1 Installation Manual

Figure 1 Airflow through the device
To ensure good ventilation, follow these guidelines:
•
The air inlet and outlet vents are not blocked, and a minimum of 10 cm (3.94 in) of clearance is
reserved around the chassis.
•
The installation site has a good cooling system.

ESD prevention

CAUTION:
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 human body and the ground.
To prevent electrostatic discharge (ESD), follow these guidelines:
•
Make sure the device and the floor are reliably grounded.
•
Take dust-proof measures for the equipment room.
•
Maintain the humidity and temperature in the equipment room at the acceptable range.
•
Always wear an ESD wrist strap and ESD garment when touching a circuit board or transceiver
module.
•
Place the removed interface module on an antistatic workbench, with the PCB upward, or put it
into an antistatic bag.
•
Touch only the edges, instead of electronic components when you observe or move an
interface module.
No ESD wrist strap is provided with the device. Prepare an ESD wrist strap yourself.
To attach an ESD wrist strap:
Wear the wrist strap on your wrist.
1.
Lock the wrist strap tight around your wrist to keep good contact with the skin.
2.
Attach the alligator clip of the strap to the grounding screw on the device.
3.

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the device and application
system, adversely affect the device in the following ways:
•
A conduction pattern of capacitance coupling.
•
Inductance coupling.
