| Description: | Buy HPE 877647-001 Synergy 4820C 10/20/25Gb Adapter. Genuine part with fast worldwide shipping from Euroland IT Store UK. |
| Availability: | In Stock |
The HPE 877647-001 Synergy 4820C Converged Network Adapter is a replacement networking component designed for compatible HPE Synergy compute modules. It provides two high-speed network connections supporting 10Gb, 20Gb and 25Gb operation, helping businesses maintain reliable Ethernet and storage connectivity within their existing Synergy infrastructure.
HPE 877647-001 is the replacement spare associated with the HPE Synergy 4820C adapter option 876449-B21. This makes it relevant for IT teams replacing an existing adapter or sourcing spare hardware for enterprise server maintenance.
Unlike conventional stand-up PCIe network cards, the 4820C uses the HPE Synergy mezzanine architecture and communicates through supported Synergy fabric interconnects.

Important: The supported connection speed depends on the Synergy compute module, interconnect configuration, firmware and network settings. The adapter does not provide external RJ-45 or SFP+ ports like a conventional server network card.
The HPE 877647-001 is designed specifically for compatible HPE Synergy compute modules. The Synergy 4820C adapter family is documented for selected Synergy platforms, including certain configurations of the HPE Synergy 480 and 660 compute module families.
Compatibility must be checked against the exact compute module generation, mezzanine slot and installed fabric interconnect. A matching physical connector alone does not guarantee support.
Before purchasing, verify:
For a replacement project, matching the existing 877647-001 spare identification is a useful starting point, but the complete server configuration should still be checked.
The Synergy 4820C is a converged network adapter, meaning it can support different types of network traffic through the same physical adapter.
Standard Ethernet connectivity can be used for server applications, virtual machines and management-related workloads, depending on the configured network architecture.
In supported environments, the adapter also provides FCoE and iSCSI capabilities for storage networking. This can help organisations use a converged infrastructure rather than installing separate adapters for every network function.
FCoE support should not be confused with a standalone native Fibre Channel HBA. The storage configuration must be supported by the Synergy interconnect, drivers and operating system.
HPE documents SR-IOV support for the Synergy 4820C, allowing compatible virtualisation platforms to assign network resources more directly to virtual machines.
The adapter also supports RoCEv2, which enables RDMA over compatible Ethernet networks. This can be relevant for workloads that benefit from lower communication overhead and reduced latency.
These functions require supported software, firmware and network configurations. Their availability should be confirmed before deployment.
The two part numbers identify different purchasing references for the HPE Synergy 4820C adapter family.
Although they refer to the same adapter family, packaging, documentation and included accessories may differ between a retail option kit and a replacement spare.
For maintenance purchases, confirm the supplied part number and product condition before placing an order.
Replacing a Synergy mezzanine adapter requires following the maintenance procedure for the applicable compute module.
Before removing the existing adapter, record the firmware version and current network configuration. Follow HPE’s instructions for safely removing the compute module and accessing its mezzanine expansion slots.
After installation, verify that the replacement adapter is recognised and that the expected network connections are available through the Synergy interconnect infrastructure.
Where FCoE, iSCSI, SR-IOV or RoCEv2 is used, test the relevant functions before returning the system to production.
A New or unused HPE Synergy 4820C adapter may be suitable for businesses maintaining replacement stock or upgrading supported infrastructure. Buyers should confirm packaging, product condition, warranty and availability before ordering.
A Refurbished adapter may offer a cost-effective alternative for replacing an existing Synergy networking component. Before purchase, request confirmation of physical inspection, hardware detection and relevant functional testing.
For both New and Refurbished products, warranty coverage and UK delivery arrangements should be confirmed with the supplier.
