Installing a chassis air filter (optional)
Chassis air filters are installed at the air intake vents to prevent dust from entering the chassis. Chassis air
filters of the S12500 switches are optional. You can order them as needed.
If you have ordered chassis air filters, H3C recommends you to install the air filters before mounting the
switch to the rack.
• S12508—A chassis air filter is available at both front and rear of the switch. For the installation
procedures, see "
Installing an air filter on an S12508 ."
• S12518—The air filter is located at the rear of the chassis. For the installation procedures, see
" Installing an air filter on an S12518 ."
