Replacing the Controller Memory Cache

Modules

The two memory cache modules in the RAID controller are replaced by removing the controller from the pedestal to gain access to the modules. Then, place the controller on a flat working surface and proceed as follows:

WARNING: To prevent an electrical discharge from damaging the SIMMs, always wear an ESD wrist strap connected to a suitable ground when handling the memory chips.

1.Power down the pedestal first and then the UPS.

2.Grasp the latches on the front of the controller and pull them forward until the controller disengages from the pedestal (Figure 3–11).

3.Remove the controller from the pedestal and place on a flat working surface.

4.Remove the two installed cache memory SIMM modules by releasing the locking clips at each end of the module until it disengages and snaps into an upright position as shown in Figures 3–12 and 3–13.
