HPE J9731A 2-port SFP+ expansion

This HPE expansion module adds two SFP+ slots to an HP 2920 switch. It is built for network administrators who need extra fibre uplinks or direct-attach links in a campus or data-centre rack. The module slides into the switch chassis and is ready for compatible transceivers. It suits teams expanding bandwidth without replacing the core switch.

Fits HP 2920 chassis slot

Installation uses a single module bay on the HP 2920, leaving other bays free for stacking or additional uplinks. No external power supply is required because the module draws power from the host switch. The two SFP+ cages accept a mix of short-range, long-range or copper direct-attach cables. This flexibility lets the same hardware serve different link distances.

Adds two SFP+ ports to fixed-configuration 2920

The upgrade replaces reliance on the switch’s built-in copper ports for inter-switch links. It becomes worthwhile when existing 1 GbE uplinks saturate or when new fibre runs are provisioned. Sites staying with copper-only connectivity or not using the 2920 platform will not benefit from this module.

Questions about this item

What limits throughput first when the two SFP+ uplinks run at full load?

The module provides two SFP+ slots; total uplink capacity is limited by the transceivers you install and the 2920 switch backplane

How does the module affect heat or fan noise inside a 2920 running continuously?

The module itself has no fan and draws power from the 2920 chassis; any extra heat is handled by the switch's existing cooling

What must already be in place for this module to function?

An HP 2920 switch with a free expansion slot plus compatible SFP+ transceivers and cables
