HP ProLiant iLO 4 Management Controller (CORE) Driver

The HP ProLiant iLO 4 Management Controller (CORE) driver helps Windows recognize and communicate with the integrated management controller in compatible HP ProLiant servers. It is intended for administrators who need the correct host-side interface for supported management software or want to resolve a missing management-controller driver in Device Manager.

Key Features

• Controller recognition: Helps Windows identify the iLO 4 management controller rather than listing it as an unknown or unconfigured device.
• Host-side communication: Provides a driver interface used by compatible management tools to communicate with the controller from the operating system.
• Management software support: Supports the underlying connection required by applicable HP server utilities; available functions depend on the server and software installed.
• Targeted compatibility: Designed for applicable ProLiant hardware with iLO 4. It is not a replacement for iLO firmware and does not add iLO capabilities to unsupported systems.

How to Install HP ProLiant iLO 4 Management Controller (CORE) Driver

1. Identify your hardware and Windows edition. Check the exact ProLiant server model, installed operating system, and system architecture. For Windows 11, 10, 8, or 7, verify that the package explicitly supports your configuration. Windows 10/11 compatibility should not be assumed from the device name alone.
2. Choose a matching package. Before starting an HP ProLiant iLO 4 Management Controller (CORE) driver download for Windows, review the package details and supported hardware list. Select the latest version validated for your system, not simply the newest available release.
3. Download and prepare. Obtain the free download from a trusted source, check its digital signature when available, and extract the files if necessary. On a production server, schedule installation during a maintenance window.
4. Install the driver. Run the supplied installer with administrator privileges and follow its prompts. If the package provides driver files without an installer, use Device Manager, select the controller, choose Update driver, and browse to the extracted folder.
5. Verify the result. Restart if requested, then check Device Manager for warning icons. Confirm that any supported management utilities can access the controller as expected.

Keep the driver updated when a compatible release addresses a relevant issue or meets your management software’s requirements. Review release notes before each update, and assess iLO firmware separately: updating the Windows driver does not update the controller’s firmware.

Common Issues and Fixes

• Install fails or rolls back: Stop HP Insight Management Agents and remove any older iLO 4 driver first, then reboot and run the installer as administrator. Check Device Manager for error Code 10/28.
• Device not detected: Confirm iLO 4 is enabled in RBSU/BIOS and configured in iLO. Reset iLO, update its firmware, then rescan hardware in Device Manager for the ProLiant iLO 4 Management Controller.
• Version conflicts: Match the CORE driver to your ProLiant generation and iLO 4 firmware. If Windows Update or an HPE package replaces it, roll back in Device Manager, remove the conflicting driver, and reinstall the extracted HP package.
