Removal and replacement procedures 51
CAUTION: Do not use this controller with cache modules designed for other controller
models, because the controller can malfunction and you can lose data. Also, do not transfer
this cache module to a different controller module, because you can lose data.
1. Back up all data.
2. Close all applications.
3. Power down the server.
CAUTION: In systems that use external data storage, be sure that the server is the first unit to
be powered down and the last to be powered back up. Taking this precaution ensures that
the system does not erroneously mark the drives as failed when the server is powered up.
4. Remove the server from the rack.
5. Remove the access panel.
6. Install the storage controller, if not installed.
7. Connect the capacitor pack cable to the connector on the top of the cache module.
8. Install the cache module.
