Replacing the Air Filter

If the air filter is dirty or clogged, the fan assembly module could have a problem providing sufficient

cooling airflow throughout the chassis, causing the system to overheat. To prevent a potential

overheating problem, you should replace the air filter approximately every 6 to 12 months, depending

on how clean and dust-free your operating environment is normally. In certain environments where the

air quality is poor, you may have to replace the filter more frequently.

Note The product order number for a replacement air filter is UBR10-FAN-FILTER=.

Use the following procedure to replace the air filter:

Step 1 Remove the front cover (see “Removing the Front Cover”).

Step 2 Slide the air filter out of its slot.

Step 3 Discard the old filter.

Step 4 Position the new air filter above the tabs on the inside of the bezel and slide it down into the slot. When

fully inserted, it should appear as shown in

Figure 5-4.
