HPE JH406A 8 Port 100GBase-X QSFP28 Module

HPE JH406A Networking 5950 8-Port QSFP28 Switch Module

The HPE JH406A Networking 5950 8-Port QSFP28 Module is a high-speed Ethernet expansion module designed for selected HPE FlexFabric 5950 switches. It provides eight QSFP28 interfaces supporting 40GbE and 100GbE connectivity, allowing businesses to expand network capacity within compatible modular switching infrastructure.

Designed for data centre networking, the JH406A is suitable for organisations upgrading switch uplinks, connecting high-bandwidth network equipment or replacing an existing module. Its QSFP28 architecture supports compatible optical transceivers and direct-attach connections, subject to HPE’s approved hardware and software configurations.

This product is a switch expansion module, not a standalone network switch or PCIe server adapter. It must be installed in a supported HPE FlexFabric switch chassis.

HPE JH406A Technical Specifications

Technical note: The 800Gbps figure represents the theoretical sum of eight 100Gbps port rates. Actual network throughput depends on the switch chassis, installed modules, traffic patterns, software and network configuration.

Key Features and Benefits

• Eight high-speed Ethernet ports: Provides additional connectivity for supported data centre switching environments.
• 100GbE capability: Supports connections operating at up to 100Gbps per port.
• 40GbE support: Allows deployment with qualified QSFP+ transceivers and cables.
• Modular expansion: Adds network interfaces to compatible HPE FlexFabric 5950 switches without replacing the entire chassis.
• Flexible connectivity: Supports approved optical and copper connection options.
• Replacement convenience: Provides a part-number-specific option for maintaining existing HPE networking infrastructure.

Compatible HPE FlexFabric Switches

HPE documents JH406A as an expansion module for selected switches in the HPE FlexFabric 5950 series.

Compatibility must be checked against the exact switch model, available expansion slot, hardware configuration and installed Comware software release.

Before ordering, confirm:

• The switch model and product number.
• Whether the chassis supports JH406A.
• The available module slot and existing configuration.
• The installed software version.
• The intended QSFP28 or QSFP+ transceiver part numbers.
• Power, cooling and cabling requirements.

The JH406A should not be assumed compatible with every HPE 5950, 5930 or Aruba switch. Use the applicable HPE QuickSpecs and transceiver compatibility documentation to verify support.

40GbE and 100GbE QSFP28 Connectivity

The HPE JH406A provides eight physical QSFP28 interfaces. HPE documents support for both 40GbE QSFP+ and 100GbE QSFP28 connectivity within qualified configurations.

This allows network administrators to select connection types according to their existing infrastructure and planned bandwidth requirements.

For example, a supported 40GbE connection may be useful when maintaining older high-speed network equipment, while a qualified 100GbE connection can provide greater capacity for newer network uplinks.

The actual connection type depends on the selected transceiver or cable, supported software and the equipment connected at the other end.

Important: QSFP28 is the physical port format. It does not mean every QSFP28 transceiver, cable or breakout configuration is supported. Confirm the exact HPE-approved components before purchase.

Data Centre Network Expansion Applications

Businesses operating modular HPE switching infrastructure may use the JH406A for several networking requirements.

• Adding high-speed connections between compatible switches.
• Expanding network capacity for server and storage infrastructure.
• Supporting high-bandwidth aggregation links.
• Replacing an existing JH406A module during hardware maintenance.
• Maintaining established 40GbE connections while planning suitable 100GbE upgrades.

Actual deployment options depend on the capabilities of the host switch and the network architecture.

JH406A vs Other HPE 5950 Expansion Modules

HPE offers different module options within the FlexFabric switching family. Selecting the correct part number is important because port formats and supported features differ.

• JH406A: Eight 40GbE/100GbE QSFP+/QSFP28 ports.
• JH405A: Sixteen 40GbE QSFP+ ports.
• JH450A: Twenty-four SFP28 ports and two QSFP28 ports.
• JH957A: Eight-port QSFP28 MACsec module for supported configurations.

These modules are not automatically interchangeable. Verify the switch chassis and feature requirements before selecting an alternative.

Installation and Replacement Considerations

Before installing HPE JH406A, review the maintenance instructions for the relevant FlexFabric 5950 switch.

Record the existing port configuration and connected cables before replacing a module. Confirm that the replacement has the correct part number and that the switch software supports it.

After installation, check that the switch recognises the module and that the expected interfaces appear in the management system.

Verify the link speed, transceiver compatibility and port status before returning affected network connections to production.

Whether the module can be replaced without powering down the chassis must be determined from the specific switch’s maintenance documentation.

New and Refurbished HPE JH406A

New HPE JH406A

A New or unused HPE JH406A module may be suitable for network expansion projects or planned replacement inventory. Before purchasing, confirm stock availability, packaging, included accessories and warranty terms.

Refurbished HPE JH406A

A Refurbished module may offer a cost-effective option for maintaining existing FlexFabric switching infrastructure. Buyers should request confirmation of physical inspection, module recognition and functional port testing.

For either condition, check whether QSFP28 transceivers or network cables are included. These components should not be assumed to form part of the supplied module.
