Flash-backed write cache procedures
Two types of procedures are provided for the FBWC option:
• Removal and replacement of failed components:
o Removing the cache module ("Cache module" on page 41)
o Removing the capacitor pack ("FBWC capacitor pack" on page 41)
• Recovery of cached data from a failed server ("Recovering data from the flash-backed write cache"
on page 42)
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.
