Servicing the DIMMs
This section describes how to service memory modules (DIMMs). DIMMs are replaceable units that require you to power off the server. For more information about replaceable units, see Illustrated Parts Breakdown and Replaceable Units.
The Oracle Exadata Storage Server X7-2 supports a fixed base configuration of twelve 16 GB quad-rank (LR) DDR4 DIMMs. Optionally, customers can expand system memory by upgrading to twelve or twenty-four 64 GB DDR4 DIMMs.
 | Caution - These procedures require that you handle components that are sensitive to electrostatic discharge. This sensitivity can cause the components to fail. To avoid damage, ensure that you follow antistatic practices as described in Take Antistatic Measures. |
| Caution - Ensure that all power is removed from the server before removing or installing DIMMs, or damage to the DIMMs might occur. You must disconnect all power cables from the system before performing these procedures. |
