QSFP28 port
The HPE 5940 48SFP+ 6QSFP28 and HPE 5940 48XGT 6QSFP28 switches provide QSFP28 ports. The LSWM12H2Q interface module (JH409A) available for the HPE 5940 2-slot and HPE 5940 4-slot switches also provides QSFP28 ports. You can install QSFP+ modules or cables in Table 24 and Table 25, and QSFP28 modules or cables in Table 27 and Table 28 in the QSFP28 ports as needed.

![[IMPORTANT: ]](images/important.png) | IMPORTANT: A QSFP28 port cannot be split into four 10GE ports. | |
![[NOTE: ]](images/note.png) | NOTE: As a best practice, use HPE QSFP+/QSFP28 transceiver modules and cables for the QSFP28 ports. The available HPE QSFP+/QSFP28 transceiver modules and cables are subject to change over time. For the most recent list of available HPE QSFP+/QSFP28 transceiver modules and cables, contact Hewlett Packard Enterprise Support or marketing staff. | |
