IMPORTANT:
•
40-GE QSFP+ ports FortyGigE 1/0/1 through FortyGigE 1/0/4 and FortyGigE 1/0/29 through
FortyGigE 1/0/32 on an HPE FlexFabric 5940 switch (JH396A) cannot be split into
10-GE SFP+ ports.
•
On an HPE 5940 4-slot switch (JH398A), the 40-GE QSFP+ ports on the LSWM124XGT2Q
(JH182A), LSWM124XG2Q (JH181A), LSWM124XG2QL (JH180A), and LSWM124XG2QFC
(JH184A) interface modules cannot be split into four 10-GE SFP+ ports. The two
highest-numbered 40-GE QSFP+ ports (ports 7 and 8) on an LSWM18QC (JH183A) interface
module cannot be split into four 10-GE SFP+ ports.
NOTE:
•
As a best practice, use HPE QSFP+ transceiver modules, QSFP+ cables, or QSFP+ to 4 x SFP+
cables for the QSFP+ ports on the switch. The HPE QSFP+ transceiver modules, QSFP+ cables,
and QSFP+ to 4 x SFP+ cables available for the QSFP+ ports are subject to change over time.
For the most recent list of QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to 4 x SFP+
cables available for the QSFP+ ports, contact Hewlett Packard Enterprise Support or marketing
staff.
•
You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver module to
connect a QSFP+ port to four SFP+ ports. The QSFP+ transceiver module and SFP+ transceiver
modules to be connected must be the same in specifications, including central wavelength and
fiber type.
For more information about HPE QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to 4 x
SFP+ cables, see

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 switch (JH397A)
and HPE 5940 4-slot switch (JH398A) also provides QSFP28 ports.
The QSFP28 fiber ports on an LSWM12H2Q interface module support QSFP+ modules in

They do not support QSFP+ to SFP+ cables.
The QSFP28 fiber ports on an LSWM18CQMSEC interface module support only QSFP+ modules
