CAUTION: The cache module connector does not use the industry-standard DDR3 mini-DIMM
pinout. 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.
To install the component:
1. Back up all data.
2. Close all applications.
3. Power down the server (on page 25).
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. Extend the server from the rack (on page 25).
5. Remove the access panel (on page 26).
6. Remove the SPI board (on page 28).
7. Install the FBWC module.
