IMPORTANT:
•
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.
•
The LSWM12H2Q interface module (JH409A) can only be installed in the two interface module
slots on an HPE 5940 2-slot switch (JH397A) and in interface module slots 1 and 2 on an HPE
5940 4-slot switch (JH398A). On an HPE 5940 2-slot switch, an interface module slot supports
hot swapping of LSWM12H2Q interface modules only if it starts up with an LSWM12H2Q
interface module installed. On an HPE 5940 4-slot switch, both interface module slots 1 and 2
support hot swapping of LSWM12H2Q interface modules if one of them starts up with an
LSWM12H2Q interface module installed. If both the slots start up empty, neither of them
supports hot swapping of LSWM12H2Q interface modules.
•
You can install the LSWM12H2Q and non-LSWM12H2Q interface modules on the same HPE
5940 2-slot switch. If an interface module slot starts up with an LSWM12H2Q interface module
installed, you can hot-swap only LSWM12H2Q interface modules in the slot. If an interface
module slot starts up empty or with a non-LSWM12H2Q interface module installed, you can
hot-swap only non-LSWM12H2Q interface modules in the slot. If you change the interface
module type in a slot, you need to reboot the switch for the interface module to operate correctly.
•
You must install the same type of interface modules either LSWM12H2Q or non-LSWM12H2Q in
interface module slots 1 and slot 2 on the same HPE 5940 4-slot switch. If one or both of the
interface module slots start up with an LSWM12H2Q interface card installed, you can hot-swap
only LSWM12H2Q interface modules in the two slots. If both interface module slots start up
empty, or one or both of the interface module slots start up with a non-LSWM12H2Q interface
module installed, you can hot-swap only non-LSWM12H2Q interface modules in the two slots.
•
An LSWM18CQMSEC interface module can only be installed on an HPE 5940 2-slot switch
(JH397A) or an HPE 5940 4-slot switch (JH398A). It supports QSFP+ transceiver modules and
cables but does not support QSFP28 modules or cables.
For more information about the interface modules, see the user manuals for the interface modules.
