Replacing the Air Filter

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.
