HPE - 406770-B21 - HP NC373M PCI EXPRESS DUAL PORT MULTIFUNCTION GIGA

HPE NC373M PCIe Dual-Port Gigabit Network Adapter

The HPE 406770-B21 (HP NC373M) is a PCI Express dual-port multifunction Gigabit Ethernet network adapter designed to add reliable 1GbE connectivity to compatible HPE ProLiant server platforms. With two Gigabit Ethernet ports on a single PCIe adapter, it supports common data center needs such as redundant network paths, segmented traffic, or dedicating one port to management and another to production workloads.

This adapter is a practical choice for maintaining or expanding existing HPE environments where stable 1GbE connectivity is required alongside upstream infrastructure such as SWITCH hardware. It can also be used in builds where you are standardising spare parts across fleets of similar ProLiant systems from the same generation.

For broader sourcing of refurbished enterprise parts in the same ecosystem, you can also browse HPE hardware categories and related connectivity options such as NETWORK MODULE components.

Key Features

Key technical highlights for server integration and day-to-day operations:

• Dual Gigabit Ethernet (1GbE) ports to provide link redundancy or separate traffic types such as management and data.
• PCI Express host interface to integrate into standard ProLiant PCIe expansion slots for server-side networking upgrades.
• Multifunction network adapter design to consolidate connectivity on one card for simplified cabling and slot usage.
• Compatible with selected HPE ProLiant servers (example families include ProLiant DL and ML series) to support lifecycle maintenance and like-for-like replacements.
• Two physical network interfaces to support common configurations such as active/standby teaming or dual-homed server connectivity.
• Enterprise NIC feature set typical for this class to support stable operation under sustained 24/7 server workloads.
• Designed for data center and server room deployments to help maintain consistent network connectivity in production environments.
• Suitable for replacement scenarios to restore failed ports or standardise spares across compatible ProLiant platforms.

Refurbished Quality and Warranty

This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished network adapters are a solid option when you need to keep existing server infrastructure running, extend hardware lifecycles, and reduce electronic waste while controlling budget compared to buying new.

All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. Direct Hardware Supply is an international supplier of refurbished IT hardware shipping worldwide from Denmark, supporting maintenance providers, system integrators, and data center operations.

If your deployment requires optical uplinks elsewhere in the network, consider matching cabling and optics via TRANSCEIVER options (where supported by your switch or server-side hardware).
