HPE 2-port 40GbE QSFP+ Module
The HPE J9996A is a 2-port 40GbE QSFP+ v3 zl2 expansion module designed for the 5400R zl2 Switch Series. It provides 40 Gigabit Ethernet connectivity over optical fiber with a maximum data transfer rate of 40 Gbit/s. The module occupies two QSFP+ expansion slots and is built for data networking and optical network environments. It weighs approximately 1.61 lb with dimensions of 1.8" height, 10.3" width, and 8.1" depth.
Network engineers expanding 5400R zl2 capacity
This module suits administrators adding high-speed uplinks or interconnects to an existing HPE 5400R zl2 switch chassis. It is not intended for use with other switch families or non-zl2 chassis, nor does it support copper-based 40G connections. Buyers needing compatibility outside the 5400R zl2 series should look elsewhere.
Two QSFP+ ports at 40 Gbit/s each
The two QSFP+ slots deliver 40 Gbit/s per port for optical fiber links using 40GBase-X technology. This headroom handles aggregation, core uplinks, and high-throughput server connections within the supported chassis. Capacity ends at the two available ports; larger port-count requirements would need additional modules or a different chassis configuration.

Questions about this item
What switch chassis is required for the J9996A module to operate?
The module is compatible only with the HP 5400R zl2 Switch Series, so that chassis must already be installed.
Will the two QSFP+ ports negotiate down to 10 Gbit/s if I connect legacy SFP+ transceivers with a QSA adapter?
The module supports 40GBase-X at 40 Gbit/s per port; speed negotiation depends on the transceiver and switch firmware, not on the module itself.
How can I confirm both ports are linked at 40 Gbit/s after installation?
Check the switch port status LEDs and run the appropriate show interface command on the 5400R zl2 to verify each QSFP+ port reports a 40 Gbit/s link.
