In addition, each AC or DC power module at the bottom of the chassis has
A replaceable air filter is located on the front of the chassis below the PLIM card cage. Each power module also has a replaceable air filter that attaches to the module at the front side of the chassis. How often you should replace the air filters depends on the facility environment.
In a dirty environment or when you start getting frequent temperature alarms, you should always check the intake grills for debris, and then check the air filters to see if they need to be replaced.
Note We recommend that you check the air filters once a month. Replace a filter when you notice a significant amount of dust.
