Cooling system
The MSR1000 router adopts left to right airflow for heat dissipation.

Airflow through the MSR1000 chassis
To ensure good ventilation, the following requirements must be met:
•
Leave at least 10 cm (3.94 in) of clearance at the air inlet and outlet vents.
•
The installation site has a good cooling system.
ESD prevention
CAUTION:
Check the resistance of the ESD wrist strap for safety. Make sure the resistance reading is 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 router and the floor are reliably grounded.
•
Take dust-proof measures for the equipment room.
•
Maintain the humidity and temperature at a compliant level.
•
Always wear an ESD wrist strap and ESD cloth when touching a circuit board or transceiver module.
An MSR1000 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.
