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 12500E switches are optional. You can order them as needed.
If you have ordered chassis air filters, HP recommends you to install the air filters before mounting the switch to the rack.
12508E—The air filter is located at the front of the chassis. For the installation procedures, see "Installing an air filter on a 12508E."
12518E—The air filter is located at the rear of the chassis. For the installation procedures, see "Installing an air filter on a 12518E."
