Extension plate HPE P48802-B21 Silver ProLiant DL380 Gen11

The HPE P48802-B21 silver extension plate is designed for use with the ProLiant DL380 Gen11 server to enable expanded drive and riser configurations. Manufactured to align with HP Enterprise mechanical and thermal requirements, this extension plate supports 2U x8/x16/x8 layouts and provides a reliable interface between server chassis and add-on components. The accessory is intended to maintain system compatibility while facilitating hardware reconfiguration and capacity upgrades.

Advantages

The extension plate provides a precise fit for the ProLiant DL380 Gen11 chassis and helps ensure stable mechanical mounting for risers and expansion cards. Its silver finish matches the server aesthetic while offering corrosion resistance. By supporting multiple lane configurations (x8/x16/x8) it increases flexibility for different I/O and storage topologies without requiring major chassis modifications.

Suitable for

• Upgrading or reconfiguring a ProLiant DL380 Gen11 server for additional expansion cards or drive controllers
• Server maintenance and replacements where factory-style mechanical parts are required
• IT environments requiring predictable mechanical compatibility for system builds and repairs

How to use

Install the extension plate into the designated bay or mounting points of the ProLiant DL380 Gen11 chassis following standard service manual instructions. Power down the server and disconnect all power sources before performing the installation. Align the plate with the chassis mounting holes and secure with the appropriate fasteners. After mechanical installation, attach riser cards or expansion modules to the plate as required, then verify seating and connections before powering the system back on.

Recommendations

Use this extension plate with genuine or compatible HP Enterprise components and follow the ProLiant DL380 Gen11 service documentation for torque values and grounding procedures. Verify firmware and hardware compatibility for any risers or expansion cards to be installed, and perform a post-installation hardware check to confirm that the system recognizes installed components.
