Dual in-line memory modules (DIMMs) provide random access memory (RAM) for the central processing units (CPUs) in the Pilot. A failed DIMM would cause the Pilot to fail and must be replaced as soon as possible.
- Prerequisites:
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.
Fail over the Pilot before replacing the component using Guided Maintenance.
Note: The Pilot must be failed over to prevent data loss or data corruption during the component replacement process.
Each Pilot has two standard DIMMs with an 8 GB memory. DIMMs are connected to the DIMM slots located on both sides of the central processing unit (CPUs) and heatsinks on the Pilot motherboard. DIMMs are customer replaceable units (CRUs) but are not hot-swappable. Replacing a DIMM requires you to power off the Pilot. The following figure shows the location of the DIMMs on the Pilot motherboard and DIMM LEDs.

Note: The DIMMs can be accessed only after removing the cover over the Pilot chassis.
Note: To replace a DIMM, you do not need to remove the Pilot from the rack but extend it along the Pilot rails using the cable management arm (CMA).
