SMUGDESK PCIe X8 Riser Adapter for HP 561FLR-T Intel X540-T2 Dual 10GBASE-T RJ45 10G Server Network Card

SKU CH-PBD5-YGHBB

A PCIe X8 riser adapter converts the HP 561FLR-T FlexibleLOM card to a standard slot, delivering dual 10GBASE-T RJ45 ports with 1G/10G auto-negotiation

  • Converts HP FlexibleLOM 561FLR-T to standard PCIe X8 slot
  • Dual RJ45 10GBASE-T ports auto-negotiate 1G and 10Gbps
  • PCIe 2.1 X8 bandwidth with passive heatsink for 24/7 operation
  • Enterprise features: SR-IOV, RSS, PXE, WoL, 9.5KB jumbo frames, 802.1Q VLAN, IEEE1588
  • Broad OS support: Windows, Linux, FreeBSD, VMware ESXi for NAS and virtual hosts

Compatibility & Installation

This PCIe X8 riser adapter converts the HP 561FLR-T FlexibleLOM network card to a standard PCIe X8 slot for desktop and common server motherboards. It is designed exclusively for OEM part numbers 700697-001 and 701525-001, enabling installation in systems lacking the proprietary FlexibleLOM connector. The riser provides a direct mechanical and electrical bridge for the Intel X540-T2 dual 10GBASE-T controller.

Target Use Cases

This solution suits builders upgrading home labs, NAS appliances, virtualization hosts, or multi-WAN routers with cost-effective 10 GbE copper connectivity. It supports SR-IOV, RSS offload, PXE boot, WoL, 9.5 KB jumbo frames, 802.1Q VLAN, link aggregation, and IEEE 1588 clock synchronization. Buyers needing fibre SFP+ ports, single-port 10G, or a low-profile bracket without the riser should consider other options.

Deciding Specification

The critical specification is the PCIe 2.1 X8 interface requirement on the host motherboard. The adapter occupies a physical X8 slot and negotiates at PCIe 2.1 speeds to deliver full duplex near line-rate throughput for the dual RJ45 ports. Verify the motherboard provides an available PCIe X8 electrical link; X4 or X1 slots will limit bandwidth and may prevent the card from functioning at 10 Gbps.

Questions about this item

How do I confirm the adapter and Intel X540 controller are operating correctly after installation?

Verify the link LEDs on both RJ45 ports show active 10G connections, check the OS network stack reports dual 10GBASE-T interfaces with SR-IOV and RSS enabled, and confirm PXE boot and WoL function during a cold start test.

What is included in the box and what must I supply myself?

The package contains the custom PCIe X8 riser board matched to the HP 561FLR-T OEM card (PN 700697-001/701525-001) with its onboard passive heatsink; you must provide Cat6A cables for 10G links up to 100 m and a standard PCIe X8 slot on the motherboard.

Which version of the riser-plus-card combo should I choose for my setup?

This single SKU pairs the PCIe 2.1 X8 riser converter with the Intel X540 dual-port 10GBASE-T NIC; select it when you need two RJ45 10G ports with 9.5 KB jumbo frames, 802.1Q VLAN, link aggregation and IEEE 1588 clock sync on Windows, Linux, ESXi or BSD systems.
