HPE P47233-B21 ML350 Gen11 SFF Tri-Mode PCIe Cable Kit

Overview

The HPE P47233-B21 is a Small Form Factor (SFF) Tri-Mode PCIe cable kit engineered specifically for the HPE ProLiant ML350 Gen11 server platform. When configuring an ML350 Gen11 with SFF drive bays alongside PCIe-attached storage controllers — such as Tri-Mode adapters that bridge SAS, SATA, and NVMe on a single controller — this internal cable assembly provides the physical interconnect that completes the backplane-to-controller signal path. Without it, the backplane cannot communicate with the HBA or RAID controller, leaving drive bays inoperable regardless of firmware or software configuration.

Compatibility

Designed for the HPE ProLiant ML350 Gen11 tower server in SFF drive bay configurations. This kit applies specifically to builds pairing SFF drive backplanes with Tri-Mode PCIe storage controllers (e.g., HPE Smart Array Gen11 or MR Gen11 series adapters). It is not interchangeable with LFF (Large Form Factor) cable kits or with Gen10/Gen10 Plus variants — cable routing, connector pitch, and backplane interface differ across generations. Verify your ML350 Gen11 configuration guide or server accessory compatibility matrix before ordering to confirm the correct cable option for your specific backplane and slot assignment.

Installation Notes

The kit ships as a pre-terminated assembly measuring 12.60 × 9.00 × 2.00 in and weighing 0.80 lb — sized to route cleanly within the ML350 Gen11 tower chassis without cable management adapters. Installation is performed during initial server build or storage controller upgrade; the chassis must be powered down and the PCIe riser accessible. Connector seating should be confirmed by hand pressure until the latch clicks — a partially seated PCIe cable is the most common source of drive-bay enumeration failures during POST.
