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.
To install the component:
1. Back up all data.
2. Close all applications.
3. Power down the server (on page 22).
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.
