  • Reliable cache protection for Smart Array controllers
  • Compatible with P420 P421 P222 P822 cards

FBWC Capacitor Pack for Smart Array Cards

This capacitor pack provides flash-backed write cache protection for compatible HP Smart Array controllers. It is designed for system administrators maintaining P420, P421, P222 or P822 cards in server environments. The assembly replaces the original FBWC module to preserve cached data during unexpected power loss.

Replaces Failed or Depleted FBWC Modules

Install this pack when the existing capacitor assembly has reached end of life or shows a fault indicator on the controller. The upgrade is worth it if write-cache functionality has been disabled due to capacitor degradation. It is not for controllers outside the listed P-series models or for systems that do not use flash-backed write cache.

Questions about this item

Which Smart Array cards does this capacitor pack fit?

It is compatible with P420, P421, P222 and P822 Smart Array cards.

How do you install the capacitor pack on the FBWC module?

Align the pack with the connector on the FBWC module and press firmly until it clicks; the step often missed is not seating it fully, which prevents the cache from powering up.
