Replace a Controller DIMM

Dual in-line memory modules (DIMMs) provide random access memory (RAM) for the central processing units (CPUs) configured in the Controller. DIMMs are connected to the DIMM slots located on both sides of the central processing unit (CPUs) and heat sinks on the Controller motherboard. A failed DIMM might cause the Controller 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.
Fail over the Controller before replacing the component using Guided Maintenance.

Note: The Controller must be failed over to prevent data loss or data corruption during the component replacement process.
Ensure that all DIMM slots are filled with either filler panels or DIMMs to ensure proper airflow.

A basic Oracle FS1 Flash Storage System has two standard DIMMs and a performance Oracle FS1 Flash Storage System has 12 standard DIMMs. The DIMMs in the Oracle FS1 Flash Storage System have 16 GB memory.

DIMMs are customer replaceable units (CRUs). Replacing a DIMM requires you to bring the Controller 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 Controller chassis.

Note: To replace a DIMM, you do not need to remove the Controller from the rack but extend it along the Controller 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 Controller before removing or installing the DIMM.
