Backplane board for HP Enterprise servers, model 777279-001-RFB — SAS/SATA compatible

Replacement backplane board for HP Enterprise servers, model 777279-001-RFB — SAS/SATA compatible. This backplane board provides the electrical and data interconnect between multiple hot-swap drive bays and the server chassis, enabling recognition of SAS and SATA drives and supporting data paths required by RAID controllers and storage arrays. It is intended as a service part for restoring drive connectivity and replacing faulty or damaged backplane assemblies in compatible HP Enterprise server models.

Advantages

The backplane supports both SAS and SATA drive interfaces on a single assembly, simplifying inventory and reducing the need for separate parts. It restores reliable signal routing between drive bays and the server controller, helping to recover full storage functionality without extensive reconfiguration. Designed for direct replacement in compatible server chassis, the unit is built to fit existing hot-swap drive trays and connector layouts, minimizing installation time during maintenance or repair operations.

Suitable for

• Repairing or replacing a faulty backplane in HP Enterprise server models that accept this assembly
• Restoring drive recognition and data connectivity for SAS and SATA-based storage arrays
• Server maintenance tasks that require swapping hot-swap drive interconnect modules
• IT service operations and data center hardware refurbishment

Key specifications

• Interface compatibility: SAS and SATA drive connections
• Form factor: backplane assembly designed for hot-swap drive bays in compatible HP Enterprise chassis
• Connectors: multi-lane data connectors and power distribution compatible with server drive trays
• Supports multiple drive bay channels and routing for RAID controller connectivity
• Designed for use in enterprise server environments and 24/7 operation

How to use

Power down the server and follow standard electrostatic discharge (ESD) precautions before beginning. Remove the front bezel or drive carrier access panel to reach the existing backplane, then disconnect any power and data cables attached to the old assembly. Unscrew or unclip the defective backplane and carefully extract it, preserving any mounting hardware if reusable. Install the replacement backplane so that its connector alignment matches the drive tray guides and chassis mounts, secure it with the appropriate fasteners, and reconnect power and controller cables. Reinstall drive trays and the bezel, then power on the server and verify that the system firmware and RAID controller detect all connected SAS and SATA drives. Consult the server service manual for model-specific steps and torque specifications.

Usage recommendations

Use compatible drives and controller firmware versions recommended by the server manufacturer to ensure full functionality. Verify firmware and controller settings after installation, and test drive detection and RAID integrity before returning the server to production. Keep spare mounting hardware and follow manufacturer ESD and safety procedures when handling the backplane.
