HPE 817738-B21 Ethernet 2P 562T Adapter

HPE 817738-B21 Ethernet 10Gb 2-Port 562T Server Adapter

The HPE 817738-B21 Ethernet 10Gb 2-Port 562T Adapter is a high-speed network interface card designed for compatible HPE ProLiant servers. Equipped with two 10GBASE-T RJ-45 ports and an Intel X550-AT2 network controller, it provides Ethernet connectivity for virtualisation, data-intensive applications and enterprise network infrastructure.

Unlike SFP+ adapters that require compatible optical transceivers or direct-attach cables, the HPE 562T connects through standard RJ-45 copper Ethernet interfaces. Its support for both 10GbE and 1GbE operation makes it useful for businesses upgrading existing server networks.

HPE 817738-B21 Technical Specifications

Note: Each port supports up to 10Gbps Ethernet operation. HPE’s published 40Gbps figure refers to the theoretical combined bidirectional bandwidth across both ports, not a 40Gbps connection on a single port.

Key Features and Benefits

• Dual 10GbE RJ-45 ports: Provides two high-speed copper Ethernet connections for compatible server networks.
• Intel X550-AT2 controller: Delivers the networking functionality documented for the 562T adapter.
• 1GbE backward compatibility: Allows supported connections to operate at Gigabit Ethernet speeds.
• PCIe 3.0 x4 interface: Connects through a qualified server PCI Express expansion slot.
• SR-IOV capability: Supports compatible virtualised networking environments.
• Network offload functions: Helps reduce host processor involvement in selected network processing tasks.

Compatible HPE ProLiant Servers

HPE lists the 817738-B21 adapter as an option for several ProLiant Gen10 platforms, including selected configurations of:

• HPE ProLiant DL20, DL120, DL160 and DL180 Gen10
• HPE ProLiant DL360 and DL380 Gen10
• HPE ProLiant DL385, DL560 and DL580 Gen10
• HPE ProLiant ML30, ML110 and ML350 Gen10
• Selected HPE Apollo Gen10 server systems

Compatibility must be confirmed against the exact server model, available PCIe slot, riser configuration, firmware and operating system.

For example, certain ProLiant ML30 Gen10 configurations require an additional front PCI fan and baffle kit when using supported high-speed Ethernet adapters. Review the server-specific QuickSpecs before installation.

10GBASE-T Copper Ethernet Connectivity

The HPE 562T is designed for copper Ethernet networking through two RJ-45 ports. It is suitable for environments using compatible 10GBASE-T switches and structured copper cabling.

Organisations moving from Gigabit Ethernet to 10GbE may benefit from retaining compatible RJ-45 network infrastructure while upgrading switches and cabling where necessary.

For reliable 10GbE operation, verify the cable category, cable length and switch capabilities. Cat6A cabling is commonly used for 10GBASE-T links up to 100 metres when installed to the relevant standards.

The adapter does not have SFP+ optical ports and should not be confused with the HPE 562SFP+ model.

Virtualisation and Enterprise Networking

In supported virtualisation environments, the 562T can provide dedicated Ethernet capacity for virtual machines, host networking and other server traffic.

HPE documents features including Single Root I/O Virtualisation (SR-IOV), Receive Side Scaling and network offload capabilities for the adapter family.

These features depend on compatible drivers, operating systems and server firmware. Their availability should be confirmed for the intended deployment.

For additional network resilience, administrators may configure both ports with supported network teaming or bonding features. However, two physical ports do not guarantee redundancy without suitable switching and software configuration.

HPE 562T vs 562FLR-T and 562SFP+

Although these adapters belong to related HPE networking families, their interfaces and installation requirements differ.

• 817738-B21 – 562T: Stand-up PCIe adapter with two 10GBASE-T RJ-45 ports.
• 817745-B21 – 562FLR-T: FlexibleLOM adapter with two 10GBASE-T RJ-45 ports.
• 727055-B21 – 562SFP+: Stand-up adapter with two 10GbE SFP+ ports.

The 562T is intended for supported standard PCIe expansion slots, while the 562FLR-T requires a compatible FlexibleLOM interface. The SFP+ version uses a different physical network connection.

Check the existing adapter and server specifications before selecting a replacement.

Installation and Maintenance

Before installing the HPE 817738-B21, shut down the server and follow the relevant HPE maintenance procedure.

Confirm that the required PCIe slot, mounting bracket and cooling arrangements are available. HPE’s original 562T option kit documentation includes the adapter, installation information, warranty statement and a low-profile bracket.

After installation, verify that the Intel X550-AT2 controller is recognised, install qualified drivers and confirm the link speed on both Ethernet ports.

For production systems, check network configuration, VLAN settings and any required teaming or virtualisation features before returning the server to service.

New and Refurbished HPE 817738-B21

New: New or unused HPE 562T adapters may be suitable for network upgrades and replacement projects. Confirm availability, packaging, mounting accessories and warranty terms before ordering.

Refurbished: A Refurbished 817738-B21 can provide a cost-effective solution for maintaining supported ProLiant servers. Buyers should request confirmation of hardware testing, RJ-45 port condition and successful network link operation.

For either condition, confirm the supplied part number, included bracket, warranty coverage and UK delivery arrangements.
