To avoid damage to electronic components, do not remove the processor from the SLC 5/04 Chassis until all power is removed from the power supply.Do not expose memory modules to surfaces or areas that may typically hold an electrostatic charge.
Disconnect the power supply.
Press the retaining clips at the top of the processor and press the retaining clips at the bottom of the processor.
Grasp the connector with your thumb and index finger. Lift up on the ends of the carrier.
When the end is partially raised, begin lifting the other end in the same manner. Repeat 4 until the memory module has been removed.
Place the new module on the connector. Press the module in place.
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.
Align the processor and the guides in the chassis.
Gently slide the processor in the chassis. Secure the top retainer clips and secure the bottom retainer clips.
Install a wire tie in order to secure your wiring.
Cover any unused slots. This protects the chassis.
