Removing the memory modules: 2145-CG8 or 2145-CF8

You can remove a memory module from a SAN Volume Controller 2145-CG8 or 2145-CF8 node.

Before you begin

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.
  • Locate the memory module you want to replace. You do not have to replace all of the modules.
  • If more than one DIMM is indicated by the light path diagnostics, replace the DIMMs one-at-a-time, starting at the lowest numbered DIMM slot that is indicated by the diagnostics. If the fault is isolated only to the bank of modules instead of to a particular module, exchange all modules of the bank.
    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. Steps to recover the update when a DIMM failure occurs are described at Updating the system.
  • The SAN Volume Controller 2145-CG8 node uses three modules in DIMM slots.  3 ,  6 , and  9 , as shown in Figure 1.

  • The SAN Volume Controller 2145-CF8 node uses six modules in DIMM slots  2 ,  3 ,  5 ,  6 ,  7 , and  8 , as shown in Figure 2.

About this task

Perform the following steps to remove the memory modules:

Procedure

  1. 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.
  2. Remove the node from the rack and place it on a flat, static-protective surface. See Removing a node from a rack.
  3. Remove the top cover. See Removing the top cover.
  4. Lift the baffle up, making sure that the pin comes out of the pin hole on the system board to the left of DIMM connector 8.
  5. Exchange the appropriate memory modules.
  6. Open the clips  2  by pressing them outward, as shown in Figure 3. This action pulls the memory module  3  out of the connector.

    •  1  Side connector latch
    •  2  Memory clips
    •  3  Memory module
  7. If you have other tasks to complete inside the SAN Volume Controller node, do those tasks now.
