The CPU provides data computing and processing power to the Replication Engine. A failed CPU might impact the processing power of the Replication Engine and must be replaced as soon as possible.
Caution
Ensure that all power is removed from the Replication Engine before replacing the CPU. Disconnect the power cables before performing the CPU replacement procedure.- Prerequisites:
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.
Ensure that you have the thermal grease and syringe available to clean the CPU.
Each Replication Engine has two CPUs located under the two heat sinks inside the chassis. A CPU is a small square component that contains multiple pins or connectors on the underside and is inserted pin side down into the CPU socket located in the motherboard. The CPU is a field replaceable unit (FRU). Replacing a CPU requires you to power off the Replication Engine. The following figure shows the location of the CPU on the Replication Engine motherboard.

Caution
Replacement of the Replication Engine CPU requires assistance from Oracle Customer Support.Note: The CPUs can be accessed only after removing the cover over the Replication Engine chassis.
Note: To replace a CPU, you do not need to remove the Replication Engine from the rack but extend it along the Replication Engine rails.
