8. If replacing DIMMs (see Figure 123):
a. Press down on the DIMM retaining clip at both ends of the DIMM being
removed.
b. Gently remove the DIMM from the DIMM slot.
c. Insert the new DIMM straight into the slot, ensuring that the notches in
the DIMM align with the tabs in the slot.
d. Repeat step a through step c for each DIMM.
9. In a dual-redundant controller configuration, repeat step 5 (on page 247)
through step 8, as appropriate, for the other cache module.
Note: In a dual-redundant controller configuration, both cache modules must contain
the same memory configuration. Do
not proceed unless both cache modules contain
identical amounts of cache memory.
Caution: Carefully align the cache module in the appropriate guide rails.
Misalignment can damage the backplane.
10. Insert the cache module into its bay and engage the retaining levers.
11. For BA370 enclosures only, connect the ECB cable to the cache module.
12. In a dual-redundant controller configuration, repeat step 10 and step 11, as
appropriate, for the other cache module.
13. Mount the logical units on the host.
14. If using a Windows NT platform, restart the server.
