HPE ProLiant DL380 Gen11 2U x8/x16/x8 Secondary Riser Kit

The HPE P48802-B21 is a secondary riser kit built for the HPE ProLiant DL380 Gen11 server. It adds three additional PCIe lanes—an x8 slot, an x16 slot, and a second x8 slot—inside the existing 2U chassis, giving administrators more flexibility when they need to grow a system without replacing it.

With the extra slots you can install new network adapters to boost throughput, drop in storage controllers to attach more drives, or reserve space for other specialized expansion cards. Because the kit matches the server’s factory layout, airflow stays consistent and cabling remains orderly, making it a practical upgrade in data centers where reliability and ease of maintenance matter.

Physical integration is straightforward: the riser measures 15.5 in wide, 10.4 in high, and 4.4 in deep, while the weight sits at about 2.23 lb, so it slides into the rack without affecting overall balance. The kit is supplied as a single unit, keeping inventory simple and installation direct.
