HPE DL380 GEN11 2U 3X16 Prim Riser KIT - P48803-B21

HPE P48803-B21 DL380 Gen11 2U Primary Riser Kit

Overview

The HPE P48803-B21 is a 2U primary riser kit that provisions three x16 PCIe expansion slots in the HPE ProLiant DL380 Gen11 chassis — the right part when your workload demands additional PCIe bandwidth for GPUs, HBAs, or high-speed network adapters beyond what the base server ships with. Without the correct riser, those slots either go unused or aren't physically present; P48803-B21 closes that gap for builds requiring maximum I/O density in a 2U footprint. At 0.60 lb and 10.80 x 8.60 x 1.70 in, it fits the DL380 Gen11 riser bay without modification.

Compatibility

Designed specifically for the HPE ProLiant DL380 Gen11 (2U rack form factor). The 3x16 primary riser configuration is distinct from secondary and tertiary riser options available for the same platform — confirm your chassis riser bay assignment and slot-count requirement before ordering. This kit is not interchangeable with DL380 Gen10, Gen10 Plus, or other ProLiant generations; HPE riser kits are generation- and chassis-specific. If your configuration requires fewer x16 slots or a different lane allocation, cross-reference HPE's DL380 Gen11 QuickSpecs to identify the correct riser variant for your bay.

Installation Notes

Installation targets the primary riser bay of the DL380 Gen11 — verify the bay is unpopulated or that the existing riser is the correct one to replace before removing it. The 2U chassis form factor constrains full-height, full-length card compatibility; double-height GPU or accelerator cards may require additional HPE hardware. Sourced factory-new through commercial distribution channels — no grey-market, no parallel imports.
