Cooling system
The MSR2000 router adopts left to right airflow for heat dissipation.

To ensure good ventilation, the following requirements must be met:
• The inlet and outlet air 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 an acceptable level.
• Always wear an ESD wrist strap and ESD cloth when touching a circuit board or transceiver module.
An MSR2000 router does not supply an ESD wrist wrap. Prepare an ESD wrist wrap yourself.
• Place the removed 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
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 plug into the ESD 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.
