Detailed Specifications
HPE J9731 61001 10GbE 2-Port SFP+ Expansion Module
Overview
The HPE J9731-61001 is an expansion module designed for the HPE/Aruba 2920 series switches. It adds two SFP+ ports capable of 1 Gb/s or 10 Gb/s link speeds, enabling high-speed uplinks or stacking links through fibre or DAC cabling. The module installs into a dedicated slot on the switch chassis, providing flexibility for network upgrades without replacing the main switch. Ideal for access or aggregation switches requiring higher-bandwidth uplinks, it allows migration toward 10 GbE infrastructure in campus or branch environments. The module supports the switch's management and stacking features seamlessly and is suited for environments where existing switch ports are fully-populated but additional high-speed uplink capacity is needed.
