Replacing the cache
CAUTION: Do not use this controller with cache modules designed for other controller models,
or the controller will malfunction and you could lose data. Also, do not transfer this cache
module to a different controller module, or you could again lose data.
1. Close all applications, and then power down the server. This procedure flushes all data from the
cache.
2. Disconnect the server from the AC power source.
3. Remove the controller from the server and place it on a firm, flat, nonconductive surface.
4. Remove the existing cache from the controller by pulling at both ends of the cache module with
equal force.
5. Install the new cache on the controller. Press firmly above each connector to ensure good electrical
contact. (If the cache is not properly connected, the controller cannot boot.)
6. Replace the controller in the server.
