The 4300 platform has a removable fan tray and filter. You can change or replace the fan tray and filter as part of the routine maintenance of the unit, or in the event of a fan failure. The air filter in the 4300 platform is designed to remove airborne contaminants and requires replacement during the life of the product. The fans in the fan tray run constantly while the unit is on. Over time, the fans will wear out, requiring you to replace the fan tray.
Note: We recommend that you inspect the fan tray and filter every four months. Replace the fan tray if any of the fans are not functional. Replace the filter when you replace the fan tray.
You do not need special tools to replace the fan tray and filter. You can perform this maintenance while the unit is running.
However, we recommend that you perform the fan tray and filter replacement only on the standby unit in a redundant system while the unit is powered down. After you install the fan tray and filter in the standby system, power up the unit, then force the active system to fail over and install the fan tray and filter replacement in the other unit of the redundant system.

| 4. | Slide the new fan tray and filter into the fan tray and filter slot. The tray is automatically turned on when you slide the tray completely into the chassis. |
Warning: You should not leave the unit running longer than 90 seconds without the fan tray installed.

Figures 5.1 and 5.2 show examples of the fan and filter tray assembly partially removed from the 4300 platform (your hardware may appear slightly different). You can also replace the filter without replacing the fan tray. This requires that you remove the fan tray, take out the old filter, and insert a new one.
