Replacement procedures
IMPORTANT:
Place a removed module in an antistatic bag or its original shipping materials.
Cleaning the air filters
The air filters of an S12500 switch fall into the following types:
• Chassis air filter—No chassis air filter is shipped with the S12500 chassis by default. You can order
one as needed.
• Power supply air filter—An S12500 chassis is installed with a power supply air filter when shipped
by default.
To guarantee good ventilation of the switch and power supplies, H3C recommends that you clear the air
filters monthly.
