Installing HS x 80 Cache Modules in Single Controller Configurations
Perform the following steps to install a cache module in a single controller
configuration.
Note: The replacement cache modules must contain the same memory configuration as
that of the cache module which was removed.
1. Insert each DIMM (see Figure 17) 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:
a. Press the DIMM gently into the slot until it is seated at both ends.
b. Engage the two retaining clips for the DIMM.
c. Make sure both ends of the DIMM are firmly seated in the slot and both
retaining clips engage the DIMM.
d. Repeat substep 1a through substep 1c above for each DIMM.
Caution: Misaligning the module might damage the backplane.
2. Carefully align and partially insert the cache module in the Cache A guide
rails.
Caution: If your cache module is in a BA370 enclosure, you must disable the
ECB. Failure to disable the ECB can result in cache module damage. To
disable the ECB, complete the following steps:
1. Disable the ECB by pressing the battery disable switch on the battery
module.
2. Connect the ECB Y-cable to the cache module.
3. Insert the replacement cache module completely into the appropriate bay, and
engage the cache module retaining levers.
4. Connect a PC or terminal to the controller maintenance port for the
replacement cache module, if not already connected.
