HPE 784304-001 10Gb 562SFP+ Adapter

HPE 784304-001 10GbE Dual-Port SFP+ Server Network Adapter

The HPE 784304-001 10GbE Dual-Port SFP+ Network Adapter is a PCI Express server networking component designed to provide high-speed Ethernet connectivity in compatible enterprise systems. HPE identifies this spare part as a Gen3 network interface card with two 10GbE SFP+ ports and an Intel XL710 controller.

For businesses maintaining established server infrastructure, this adapter provides a replacement option where the exact 784304-001 hardware is required. Its two-port configuration supports separate network connections for server traffic, virtualisation or network redundancy when the host system and switching infrastructure are configured appropriately.

Part number note: Although this product is listed under the 562SFP+ name, HPE’s published 562SFP+ retail option and spare references differ. Confirm the board identification before ordering it as a direct 562SFP+ replacement.

HPE 784304-001 Technical Specifications

Specification guidance: The exact PCIe lane configuration, supported transceivers, firmware and server compatibility should be confirmed against the physical 784304-001 board. Specifications published for other 562SFP+ part numbers should not automatically be applied to this spare.

Key Features and Benefits

• Dual 10GbE connectivity: Provides two Ethernet ports for supported high-speed server networking environments.
• SFP+ interface: Allows connections using compatible optical modules or direct-attach copper cables.
• Intel XL710 controller: Uses the controller family identified in HPE’s spare-part record.
• Flexible network configuration: Supports deployment in network architectures requiring multiple physical connections.
• Server maintenance: Helps businesses source a matching replacement component for existing infrastructure.

Server Compatibility and Replacement Checks

Compatibility should be verified using the exact HPE server model, system firmware and existing adapter identification. A PCIe slot and an SFP+ connection alone do not establish that the card is supported.

Before ordering HPE 784304-001, check:

• The part number printed on the existing network adapter.
• The server model and available PCIe expansion slot.
• The required driver and firmware versions.
• The supported SFP+ transceivers or direct-attach cables.
• The mounting bracket and chassis clearance.

If the replacement is intended for a ProLiant Gen9 or Gen10 server, consult the specific server’s HPE QuickSpecs or maintenance documentation before purchasing.

Understanding the 562SFP+ Part Number Difference

HPE’s published Ethernet 10Gb 2-port 562SFP+ Adapter uses option number 727055-B21. HPE PartSurfer identifies 790316-001 as a corresponding replacement spare.

By comparison, HPE identifies 784304-001 separately as a dual-port 10GbE SFP+ adapter using an Intel XL710 controller.

These parts may appear under similar descriptions in hardware catalogues, but the exact board identity and approved replacement relationship should be confirmed rather than assumed.

10GbE SFP+ Networking Applications

A dual-port 10GbE adapter can be useful in server environments where administrators need dedicated connections for different traffic types or network paths.

Depending on the supported server and software configuration, common applications include virtual machine traffic, storage networking over Ethernet, server-to-switch uplinks and network segmentation.

For resilient connectivity, each port can be connected to appropriate switching infrastructure. However, redundancy depends on switch configuration, network teaming or bonding support and the operating system.

This adapter is intended for Ethernet networking. It is not a Fibre Channel SAN host bus adapter and should not be connected to a Fibre Channel switch as though it were an FC HBA.

Installation and Maintenance Guidance

Before installation, power down the server and follow the applicable HPE maintenance procedure. Check that the adapter is correctly seated in a supported expansion slot and that the required mounting bracket is available.

After installation, verify that the operating system recognises the network controller and that the appropriate driver is installed. Check both port links using qualified SFP+ modules or cables.

For replacement projects, recording the existing firmware, driver and network settings can help reduce configuration differences when the new adapter is installed.

New and Refurbished HPE 784304-001

New: New or unused HPE 784304-001 adapters may be suitable for replacement projects requiring this exact part number. Confirm stock availability, packaging, bracket type and included accessories before purchase.

Refurbished: A Refurbished adapter may provide a cost-effective way to maintain an existing server. Buyers should request confirmation of physical condition, hardware detection and operation of both Ethernet ports.

For either condition, confirm whether SFP+ transceivers or DAC cables are included. Warranty terms, testing arrangements and UK delivery options should be checked with the supplier.
