HPE P48805-B21 ProLiant DL380 Gen11 2U Primary/Secondary NEBS Riser Kit

Overview

The HPE P48805-B21 is a NEBS-compliant riser kit designed for the ProLiant DL380 Gen11 2U rack server, supporting both the primary and secondary riser positions. NEBS (Network Equipment Building System) compliance matters in telecom central office and carrier-grade data center deployments where equipment must meet GR-63 and GR-1089 environmental and electrical standards — this riser carries that qualification into the DL380 Gen11 chassis without requiring a separate validated card cage. For integrators building out edge compute nodes or telecom infrastructure on the HPE ProLiant platform, P48805-B21 is the path to expand PCIe connectivity while maintaining NEBS certification at the system level.

Compatibility

This riser kit is specified for the HPE ProLiant DL380 Gen11 (2U rack form factor). It is not interchangeable with Gen10 or Gen10 Plus chassis — the DL380 Gen11 introduced a revised riser architecture, and prior-generation risers are physically and electrically incompatible. Verify your server's riser bay configuration (primary vs. secondary slot population) against your PCIe expansion requirements before ordering. If your DL380 Gen11 deployment involves high-density networking add-in cards or storage HBAs, confirm card length and power envelope against the Gen11 riser specification. For full platform context, review the HPE server accessories catalog to match additional expansion components to your chassis generation.
