Replacement procedures

Place a removed module in an antistatic bag or its original shipping materials.
Cleaning the air filters
The air filters of a 12500E switch fall into the following types:
Chassis air filter—No chassis air filter is shipped with the 12500E chassis by default. You can order
one as needed.
Power supply air filter—A 12500E chassis is installed with a power supply air filter when shipped
by default.
To guarantee good ventilation of the switch and power supplies, HP recommends that you clear the air
filters monthly. You must clean the air filter every three months at least.
Cleaning the chassis air filters
For a 12508E
Holding the notches of the front plastic panel at the bottom part of the chassis, and gently pull the
plastic panel out.
Loosen the screws that fix the chassis air filter to the rear of the plastic panel, and remove the
chassis air filter from the plastic panel.
Use clean water to wash the chassis air filter, and air-dry it.
Install the chassis air filter to the correct position. For more information, see "Installing the switch."
