NOTE:
H3C recommends that you use H3C SFP transceiver modules, SFP+ transceiver modules, or SFP+ DAC
cables for the SFP+ ports on the switch. The H3C SFP transceiver modules, SFP+ transceiver modules, and
SFP+ DAC cables are subject to change over time. For the most up-to-date list of SFP transceiver modules,
SFP+ transceiver modules, and SFP+ DAC cables, contact H3C Support or marketing staff.
For more information about H3C SFP transceiver modules, SFP+ transceiver modules, and SFP+ DAC
cables, see H3C Transceiver Modules User Guide .
QSFP+ port
The S7502E-XS switches provide fixed QSFP+ ports. The LSQM1QGS8A0, LSQM1TGT24QSM0,
LSQM1TGS24QSM0, and LSQM1TGS24QSA0 interface cards provide QSFP+ ports. You can install
QSFP+ transceiver modules in Table 17 , QSFP+ DAC cables in Table 18 , and QSFP+ to 4 x SFP+ DAC
cables in Table 19 in the QSFP+ ports as needed.
