The motherboard cables provide power, switch, or signal connectivity to the various Replication Engine components. Damage to any of these cables might impact the normal operations of the Replication Engine and must be replaced as soon as possible.
Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch shaft.
Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
