Disconnect the power supply.
Press the retaining clips at the top of the module and press the retaining clips at the bottom of the module.
Remove the processor from the chassis.
Disconnect the Battery by removing the battery connector from the socket.
To avoid potential damage to the processor, handle all modules by the ends of the carrier or edges of the plastic housing. Skin oil or dirt can corrode metallic surfaces, inhibiting electrical contact.
Connect the battery and the processor by attaching the battery connector to the socket.
Align the processor and the guides in the chassis.
Gently slide the module in the chassis. Secure the top retainer clips and secure the bottom retainer clips.
Install a wire tie in order to secure the wiring.
Cover any unused slots. This protects the chassis.
