## Long description

Backup battery for RAID controller HP P02377-B21 is designed to maintain cache power and protect write-back cache in the event of unexpected power loss. Compatible with HPE Smart Array controllers such as P824i-p MR Gen10 and P816i-a SR G10 LH, this module helps ensure stored cache data can be preserved or safely transferred to non-volatile memory. The unit measures 254 × 222.5 × 57.9 mm and is intended for use in server environments where storage reliability and safe shutdown of write operations are required.
Advantages
This backup module provides uninterrupted power to controller cache during short-term outages, enabling cached data to be secured to non-volatile storage. It is compatible with HPE Smart Array Performance Class controllers and integrates with flash-based non-volatile memory to preserve write-back data. The product also offers a reduced maintenance and environmental footprint compared with traditional lithium-ion batteries when used as part of a Smart Hybrid Capacitor solution, since the hybrid capacitor approach eliminates the need for replaceable batteries in supported configurations.
Suitable for
 Enterprise and rack-mounted servers using HPE Smart Array P824i-p or P816i-a controllers
 Systems requiring protection of write-back cache during sudden power loss
 Environments that prioritize data integrity for transactional or database workloads
 Deployments aiming to use HPE Smart Hybrid Capacitor technology as a centralized backup power source
Key specifications
 Compatibility: Works with HPE Smart Array P824i-p MR Gen10 and P816i-a SR G10 LH controllers
 Function: Provides backup power to preserve controller write-back cache and enable data transfer to non-volatile memory
 Technology: Supports HPE Smart Hybrid Capacitor architecture for battery-free power storage when applicable
 Physical dimensions: 254 mm (W) × 222.5 mm (D) × 57.9 mm (H)
 Role: Centralized backup power module for server storage reliability and safe shutdown operations
How to use
Install the backup module into the server or controller bay following the server manufacturer’s installation instructions and service manual. Ensure the target server is powered down or placed in maintenance mode if the installation procedure requires it. After physical installation, verify firmware and controller compatibility, enable any required settings in the RAID controller management utility, and confirm that the controller recognizes the backup module. In configurations using the Smart Hybrid Capacitor, ensure the system firmware and controller firmware versions support hybrid-capacitor operation and non-volatile cache handling.
Usage recommendations
Use this module in accordance with HPE installation and service guides. Regularly verify firmware compatibility and health status through the server management interface. For systems leveraging HPE Smart Hybrid Capacitor technology, keep controller and system firmware up to date to ensure proper coordination between controller cache, flash memory, and the hybrid capacitor module for reliable data preservation during power events.
