6. Loosen the thumbscrews, and lift the mezzanine board from the server. CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless all expansion slots have either an expansion slot cover or an expansion board installed. To replace the component, reverse the removal procedure. Recovering data from the BBWC If the server fails, you can recover any data temporarily trapped in the BBWC by using the following procedure. CAUTION: Before starting this procedure, read the information about protecting against electrostatic discharge ("Preventing electrostatic discharge" on page 26). 1. Perform one of the following: o Set up a recovery server station using an identical server model. Do not install any internal drives or BBWC in this server. (This option is preferred.) o Find a server that has enough empty drive bays to accommodate all the drives from the failed server and that meets all the other requirements for drive and array migration. 2. Power down the failed server ("Power down the server" on page 29). If any data is trapped in the cache module, the amber LED on the module blinks every 15 seconds. CAUTION: Do not detach the cable that connects the battery pack to the cache module. Detaching the cable causes any unsaved data in the cache module to be lost. 3. Transfer the hard drives from the failed server to the recovery server station. 4. Remove the BBWC cache module ("Removing the BBWC cache module" on page 46) and battery pack ("Removing the BBWC battery pack" on page 45) from the failed server. 5. Perform one of the following: o Install the BBWC into an empty BBWC DIMM socket on the system board of the recovery server. Removal and replacement procedures 44
