HPE DL580 GEN10 6-SLOT 2P Slim Riser KIT - 872336-B21

HPE 872336-B21 6-Slot 2P Slim Riser Kit

Overview

The HPE 872336-B21 is a six-slot, two-processor slim riser kit designed to expand PCIe add-in card capacity on ProLiant DL580 Gen10 servers. If your DL580 Gen10 deployment is running short on expansion slots — whether for additional NIC cards, HBAs, or accelerators — this riser provides the physical infrastructure to populate those slots without modifying the base chassis. At 0.91 lb, it installs cleanly inside the existing chassis envelope without adding meaningful weight to rack load calculations.

Compatibility

The 872336-B21 is designed for the HPE ProLiant DL580 Gen10 server platform specifically. The DL580 Gen10 is a four-socket, 4U rack server; this riser kit supports dual-processor (2P) configurations and provides six slim-form-factor PCIe expansion slots. Verify your DL580 Gen10 is configured for the 2P riser position before ordering — the DL580 Gen10 supports multiple riser configurations, and mismatched risers will not seat correctly. This kit is not compatible with DL580 Gen9 or earlier generations, nor with other ProLiant family members such as the DL360, DL380, or DL560.

Installation Notes

Install this riser into a powered-down, fully grounded system following HPE's standard ESD precautions. Slim-form-factor PCIe cards are required — full-height or half-height standard cards will not fit the slim riser slots. Confirm available power budget on your system board before populating all six slots, particularly if installing power-hungry network adapters or storage controllers. Consult the DL580 Gen10 Maintenance and Service Guide for slot numbering, torque specifications, and supported card combinations specific to your processor and memory configuration.
