HPE Aruba JL557A — Enterprise-Class 3810M Switch with 16×10G SFP+ & 2×40G QSFP+ Ports for High-Speed Core and Aggregation Networks

Product Description

The HPE Aruba JL557A 3810M switch is a high-performance enterprise Layer 3 switch designed for campus core, aggregation, and high-density data-center environments. Built by Hewlett Packard Enterprise, this model delivers flexible high-speed connectivity by combining 16 SFP+ 10-Gigabit fiber ports with 2 QSFP+ 40-Gigabit uplink ports, enabling scalable backbone performance for modern enterprise networks.

Engineered on Aruba’s resilient switching platform, the JL557A supports advanced Layer 2/Layer 3 capabilities including dynamic routing, traffic segmentation, multicast optimization, and enterprise-grade QoS. The inclusion of native 40G uplinks makes this switch ideal for high-capacity aggregation layers, core interconnects, and virtualization-heavy environments.

With modular expansion slots, stacking support, and redundant power options, the JL557A allows organizations to scale performance and availability as network demand increases. Integration with Aruba’s network management ecosystem ensures simplified monitoring, automation, and policy enforcement across distributed infrastructures.

Its compact 1U rack-mount design makes it suitable for enterprise wiring closets, campus cores, and data-center racks requiring high throughput with minimal space usage.
