Installing an HS x 80 Cache Module in Dual-Redundant Controller Configurations
Perform the following steps to install an HSx80 cache module in a dual-redundant
controller configuration.
Caution: ESD can easily damage a cache module or a DIMM. Wear a
snug-fitting, grounded ESD wrist strap.
Note: The replacement cache module must contain the same cache memory
configuration as the module being replaced.
Note: If you are installing a cache module after resolving a failed cache state (see
Table 3 through Table 5), the operational controller and the replacement controller
references that appear in this section may have been reversed. The operational
controller is the one attached to the terminal or PC and the one from which
FRUTIL is
executed.
H 1. For the replacement cache module, insert each DIMM (see Figure 17 on
page 38) straight into the appropriate slot of the replacement cache module,
ensuring that the notches in the DIMM align with the tabs in the slot. Use the
following substeps to install the DIMMs:
H a. Press the DIMM gently into the slot until it is seated at both ends.
H b. Engage the two retaining clips for the DIMM.
H c. Make sure both ends of the DIMM are firmly seated in the slot and both
retaining clips engage the DIMM.
H d. Repeat substep 1a through substep 1c above for each DIMM.
 2. For the operational controller, complete the following substeps:
 a. Connect a PC or terminal to the operational controller, if not already
connected.
