You can remove a memory module from a SAN Volume Controller 2145-SV1 node.
Before you begin
DANGER
Multiple power cords. The product might be equipped with multiple
power cords. To remove all hazardous voltages, disconnect all power cords. (L003)
Review the following information before you begin the removal process.
The memory modules are electrostatic-discharge (ESD) sensitive. Take precautions to avoid damage
from static electricity.
Refer to Figure 1 to locate the dual inline memory
module (DIMM) that you want to replace.
The system has two processors (CPU0 and CPU1).
Each processor has four memory channels, which are labeled A-D.
Each memory channel has 3 DIMM slots, numbered 0-2. For example, DIMM slots A0, A1, and A2 are
in memory slot A.
On the system board, the DIMM slots are labeled according to their associated processor, memory
channel, and slot. For example, the label C0A0 identifies DIMM slot A0 for CPU0. If an error
occurs, the error event also includes a similar identifier (for example, CPU0_DIMMA0 or
CPU0DIMMA0).

You do not have to replace all of the modules.
Attention: If a memory DIMM failure to any node is encountered during the update process, you might be required to remove and
replace a memory module. Updating the system software describes the
steps to recover the update when a DIMM failure
occurs.
About this task
Perform the following steps to remove the memory modules.
Procedure
Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to
data in volumes before you power off the node.
Remove the node from the rack and place it on a flat, static-protective
surface. See Removing a node from a rack.
