Replace a Replication Engine DIMM

Dual in-line memory modules (DIMMs) provide random access memory (RAM) for the central processing units (CPUs) configured in the Replication Engine. DIMMs are connected to the DIMM slots located on both sides of the central processing unit (CPUs) and heat sinks on the Replication Engine motherboard. A failed DIMM might cause the Replication Engine to be brought offline and must be replaced as soon as possible.

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 all DIMM slots are filled with either filler panels or DIMMs to ensure proper airflow.

Oracle MaxRep Replication Engine has four standard DIMMs

DIMMs are customer replaceable units (CRUs). Replacing a DIMM requires you to bring the Replication Engine offline. The following figure depicts a DIMM memory module.

The following diagram indicates the location of the DIMMs in the DIMM slots.

Note: The DIMMs can be accessed only after removing the cover over the Replication Engine chassis.

Note: To replace a DIMM, you do not need to remove the Replication Engine from the rack but extend it along the Replication Engine rails using the cable management arm (CMA).

Note: All DIMM fault LEDs are located next to the DIMM slots along with the DIMM slot number.

Caution

Ensure that all power is removed from the Replication Engine before removing or installing the DIMM.
