3.8 Replacing the Controller Memory Cache Modules
The two memory cache modules in the RAID controller are replaced by remov-
ing the controller from the pedestal to gain access to the modules. Then, place
the controller on a flat working surface and proceed as follows:
CAUTION
To prevent an electrical discharge from damaging
the SIMMs, always wear an ESD wrist strap con-
nected 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 con-
troller disengages from the pedestal (see 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 posi-
tion as shown in Figures 3–12 and 3–13.
