What port configuration does the HPE JH394A provide?

The JH394A features 48 fixed 1/10GBASE-T RJ45 ports supporting auto-negotiation between 1Gbps and 10Gbps speeds, plus 6 QSFP+ ports for 40GbE uplinks. This copper-focused design eliminates SFP+ transceivers for access ports while providing high-speed fiber uplinks.

Does the JH394A support VXLAN for network virtualization?

Yes, it includes hardware VXLAN Layer 2 and Layer 3 gateway support for up to 4K tunnels. This enables overlay networks across physical boundaries, perfect for multi-tenant cloud environments and VM mobility without VTEP performance penalties.

What are the power and cooling requirements for deployment?

Requires minimum 1 hot-plug power supply and 2 fan trays. 1U rack height with redundant PSUs (not included) and fans supports high availability. Actual power draw depends on port utilization and transceivers; use HPE Power Advisor for precise calculations.

Can the JH394A ports negotiate 1Gbps speeds?

The 48x 1/10GBASE-T ports support auto-negotiation between 10Gbps and 1Gbps speeds per IEEE 802.3bz standards. However, 100Mbps is not supported on these fixed ports, making it optimized for modern 1/10GbE data center environments.

What management features does the switch offer?

Runs Comware 7 OS with IRF (Intelligent Resilient Framework) for virtual stacking up to 10 units as one logical switch. Supports RESTful APIs, OpenFlow, and EVPN for SDN integration, plus sFlow, NetStream for monitoring high-speed traffic.

Is the JH394A suitable for spine-leaf architectures?

Yes, as a leaf switch with 6x40GbE QSFP+ uplinks to spine, it delivers non-blocking 1.44Tbps switching capacity. VXLAN and EVPN support enable scalable fabrics for leaf-spine deployments handling 10GbE server traffic efficiently.

Product overview

The HPE FlexFabric 5940 48XGT 6QSFP+ Switch (JH394A) is a high-performance, low-latency top-of-rack (ToR) data center switch designed for 10GbE and 40GbE environments. It provides 48 fixed 1/10GBASE-T RJ45 ports for flexible copper connectivity and 6 QSFP+ ports supporting 40GbE uplinks, enabling non-blocking wire-speed forwarding in 1U form factor. Key features include hardware VXLAN support for up to 4K tunnels, jumbo frames up to 10,000 bytes on 1/10GbE ports for efficient remote backup and disaster recovery, and advanced Comware OS for IRF stacking and unified management. Ideal for high-density server access, spine-leaf architectures, and cloud-scale deployments requiring scalable L2/L3 services, low-latency east-west traffic, and seamless network virtualization integration.

48x 1/10GBASE-T ports enable flexible copper 10GbE server connectivity.
6x QSFP+ 40GbE uplinks provide high-bandwidth aggregation to spine switches.
VXLAN hardware support for 4K tunnels enables overlay network virtualization.
Jumbo frames up to 10,000 bytes optimize backup and replication traffic.
