What it is

  • P48802-B21 is the HPE ProLiant DL380 Gen11 2U x8/x16/x8 Secondary Riser Kit.

Why this part number

  • P48802-B21 provides Secondary Riser slots 4, 5 and 6 on Proc 2, and each of these uses PCIe 5.0.

Features

  • Slot 4: PCIe 5.0, Bus Width X8, Connector Width X16, full-height, full-length, Proc 2.
  • Slot 5: PCIe 5.0, Bus Width X16, Connector Width X16, full-height, full-length, Proc 2.
  • Slot 6: PCIe 5.0, Bus Width X8, Connector Width X16, full-height, half-length, Proc 2.

Official notes

  • Up to one Secondary Riser can be selected per server.
  • Two Secondary Riser types are supported.
  • After completing your Smart Chassis configuration, set the Smart Chassis quantity to 1. OCA will automatically select the required cables, which will appear under Storage Devices (Step 5) > Internal Storage Controller Cables.
  • No manual cable selection is required.
  • Refer to the PCIe Expansion Slot section above for detailed Riser card and accessory selection guidance.
  • Review the PCIe Expansion Slots section for slot numbering, bus width, processor requirements, and riser configuration details.
  • A second processor is required when selecting a secondary or tertiary riser.
  • The 3x16 secondary riser and tertiary riser cannot be selected together.

Compatibility & limits

  • A second processor is required when selecting a secondary or tertiary riser.
  • Up to one Secondary Riser can be selected per server.

How it differs

  • Slot 6 has Bus Width X8 on P48802-B21 and Bus Width X16 on P51083-B21.

Description

Secondary riser

The secondary riser provides extra PCIe slots, usually connected to the second processor.

It is needed to install more cards or double-wide GPUs on the second side of the chassis.

The number of installable expansion cards increases.
