SAN Volume Controller 2145-8F4 or SAN Volume Controller 2145-8F2: These modules are numbered
1
through
8
, as shown in Figure 96.
Note: If more than one SAN Volume Controller 2145-8G4, SAN Volume Controller 2145-8F4, or SAN
Volume Controller 2145-8F2 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.
Removing memory modules
This topic describes how to remove the memory modules.
Perform the following steps to remove the memory modules:
1. Follow the procedure in MAP 5350 in the IBM System Storage SAN Volume Controller Troubleshooting
Guide to verify that the node data is mirrored and synchronized, and that there are no dependent
volumes before turning off the node.
2. Remove the node from the rack and place it on a flat, static-protective surface. See “Removing the
SAN Volume Controller from a rack” on page 46.
3.
Remove the top cover. See “Removing the top cover” on page 77.
4. For the SAN Volume Controller 2145-CG8 or 2145-CF8, grasp the DIMM air baffle and 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.
Attention: If the fault has been isolated only to the bank of modules instead of to a particular
module, exchange all modules of the bank. Otherwise, if you need to remove fewer memory modules,
see “Locating memory modules” on page 104. If more than one SAN Volume Controller 2145-8G4,
SAN Volume Controller 2145-8F4, or SAN Volume Controller 2145-8F2 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.

Open the clips

by pressing them outward, as shown in Figure 97 on page 109. This action pulls
the memory module

out of the connector.
