6. Press the optical drive release lever, and then push the drive out of the bay. To replace the component, reverse the removal procedure. Flash-backed write cache procedures The following types of procedures are provided for the FBWC option: • Removal and replacement of failed components: o Removing the cache module ("FBWC module" on page 34) o Removing the capacitor pack ("Capacitor pack" on page 35) • Recovery of cached data from a failed server ("Recovering data from the flash-backed write cache" on page 37) CAUTION: Do not detach the cable that connects the battery pack or capacitor pack to the cache module. Detaching the cable causes all data in the cache module to be lost. FBWC module 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. Power down the server (on page 23). 2. Disconnect the power cord from the AC source. 3. Disconnect the power cord from the server. Removal and replacement procedures 34

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.
