The heat sink serves as a cooling device to prevent the CPU in the Replication Engine from overheating. A damaged heat sink can cause the Replication Engine CPU to overheat, which would cause the CPU to fail. You must replace a damaged heat sink as soon as possible.
Caution
Ensure that all power is removed from the Replication Engine before replacing the heat sink. Disconnect the power cables before performing the heat sink 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.
Each Replication Engine has two heat sinks located above the CPUs on the Replication Engine motherboard. Heat sinks are usually durable and need not be replaced. Heat sinks are field replaceable units (FRUs). Replacing a heat sink requires you to bring the Replication Engine offline. The following figure displays the Replication Engine heat sink.

Note: The heat sinks can be accessed only after removing the cover over the Replication Engine chassis.
Note: To replace a heat sink, you do not need to remove the Replication Engine from the rack but extend it along the Replication Engine rails.
