CAUTION: The cache module connector does not use the industry-standard DDR3 mini-DIMMs.
Do not use the 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 an
unsupported controller model, because you can lose data.
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.
To remove the component:
1. Back up all server data on the drive.
2. Power down the server (on page 25).
