Chapter 3 Installing and Removing Air Circulation Components
How to Install or Remove Air Circulation Components
Steps
To remove a power module air filter, follow these steps:
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection
sockets on the front (PLIM) side of the chassis or a bare metal surface on the chassis.
Step 2 Place the screwdriver under the edge of the air filter clip-on holder.
Step 3 Gently pry the holder loose with the screwdriver; it should pop off easily.
Step 4 Remove the air filter from the front of the power module and set it carefully aside.
What to Do Next
After performing this task, you may install a new air filter (see the “Installing a Power Module Air Filter”
section on page 3-12) and replace the front cover plates.
