HPE JL078A Aruba 3810M/2930M 1-port QSFP+ 40GbE Module
Overview
The HPE JL078A is a network module designed for engineers deploying uplink or aggregation links in campus and data-centre environments. It provides a single QSFP+ port capable of 40 Gb/s Ethernet, enabling high-bandwidth connectivity from an Aruba 3810M or 2930M switch to spine switches or aggregation fabric. With support for multimode fibre and industry-standard form factors, it allows seamless expansion of existing switch chassis without full replacement. The module installs into the dedicated uplink slot of the chassis and integrates with switch firmware for management, monitoring and link diagnostics. This makes it ideal for switching infrastructures requiring a compact, cost-effective jump to 40 Gb/s uplinks while preserving existing switching layers.
