The Hewlett Packard Enterprise J9731A is a 2-port 10GbE SFP+ switch expansion module for Aruba 2920 series switches, delivering up to 10 Gbps per port with SFP+ connectivity that supports fiber or DAC cabling. It’s a plug-in expansion module that mounts in a switch module slot (internal) to add uplink capacity and expand switch infrastructure. Common applications include campus networks, data centers, and aggregation layers where 10GbE uplinks connect switches to servers and support bandwidth-intensive workloads. Designed for enterprise environments, the J9731A serves as a straightforward upgrade or replacement for legacy uplink modules in Aruba 2920 switches.
