⚙️ Fit Notes

• This listing is for the FBWC capacitor battery pack only.
• Cache memory module is sold separately.
• Commonly used with 633540-001.
• Please verify your existing spare part number and controller configuration before ordering.
• Some systems may use the same capacitor pack across different Smart Array configurations, but compatibility should always be matched by part number and cache module setup.
• If your controller reports a failed cache capacitor or degraded FBWC status, replacing this capacitor pack may restore normal cache protection when used in the correct supported configuration.
