How to install HPE Ethernet 640FLR?

Use these general instructions to install the HPE Ethernet 640FLR Dual Port SFP28 10/25GB FlexibleLOM Adapter into your server. Please be aware that based on the model and configuration of your server, precise installation steps may differ slightly.

Pre-installation Preparation:

Shutdown the Server: Ensure the server is powered off before beginning installation to prevent any electrical hazards or damage.
Review Server Compatibility: Confirm that the HPE Ethernet 640FLR Adapter is compatible with your server model and generation. Refer to the server’s documentation or HPE’s compatibility matrix for verification.
Prepare the Workspace: Choose a clean, static-free work area with ample space to work comfortably with your server.

Installation Steps:

Open the Server Chassis:
- Remove the server cover or access panel. This typically involves unscrewing or releasing latch mechanisms on the chassis.
Locate the Expansion Slot:
- Identify an available PCIe expansion slot that matches the adapter’s form factor (FlexibleLOM). The server’s user manual or documentation should indicate compatible slots.
Insert the Adapter:
- Align the HPE Ethernet 640FLR Adapter with the PCIe slot and gently insert it into the slot until it is firmly seated.
- Secure the adapter by fastening the screw or latch on the chassis to hold it in place.
Connect the Network Cables:
- Attach SFP28 transceivers to the adapter’s ports if not pre-installed.
- Connect the appropriate network cables (fiber optic or copper) to the SFP28 ports on the adapter. Ensure proper cable management to avoid strain or disconnection.
Replace Server Cover:
- Close and secure the server cover or access panel back onto the chassis.
Power On the Server:
- Turn on the server and allow the operating system to boot up.
- Install any necessary drivers or firmware updates for the adapter. You can download these from the HPE website or use the provided installation media.
Verify Installation:
- Once the server has booted up, verify the adapter’s recognition in the operating system’s device manager or through server management tools.
- Configure network settings and verify connectivity to ensure the adapter is functioning correctly.

Post-installation Steps:

Driver Installation: If the operating system does not automatically detect the adapter, install the appropriate drivers from HPE’s website or the provided installation media.
Firmware Updates: Check for and install any firmware updates for the adapter to ensure compatibility and optimal performance.
Testing and Validation: Conduct thorough testing to ensure the adapter operates correctly under normal load conditions.

By following these steps and referring to your server’s specific documentation, you can successfully install the HPE Ethernet 640FLR Dual Port SFP28 10/25GB FlexibleLOM Adapter and integrate it into your server environment.
