Secondary Riser Kit for DL380 Gen11

The HPE P48802-B21 adds three expansion slots to a ProLiant DL380 Gen11 2U server. It is designed for administrators who need additional PCIe connectivity inside the existing chassis without changing the primary riser configuration.

x8/x16/x8 slot layout fits Gen11 2U

The kit installs into the secondary riser position of the DL380 Gen11 2U server. It provides one x16 and two x8 mechanical slots, freeing the primary riser for other configurations while keeping the server at its standard 2U height.

Three slots with mixed lane widths

The assembly weighs 1.01 kg and measures 26.4 x 39.4 x 11.1 cm. It comfortably handles cards that fit the x8 or x16 form factor, but it cannot accept cards that require a different slot spacing or a full-height bracket beyond the 2U limit.

Questions about this item

How much additional weight does the 1.01 kg riser kit add to the DL380 Gen11 2U chassis?

The riser kit weighs 1.01 kg (2.216 lbs), adding that mass to the server when installed.

What clearance is required above the secondary riser to maintain airflow during continuous operation?

The kit measures 11.1 cm (4.37 in) tall, so the chassis lid and any overhead cable routing must allow at least that height for unobstructed airflow.

Which server model must already be in the rack for this secondary riser kit to fit and function?

It is designed for the HPE ProLiant DL380 Gen11 2U server and will not align with other chassis.
