IMPORTANT:
•
The fixed QSFP+ ports on the S6520X-30QC-EI, S6520X-54QC-EI, S6520X-30QC-HI, and
S6520X-54QC-HI switches do not support the LSWM1QSTK5 cable.
•
The QSFP-40G-SR4-MM850 and QSFP-40G-CSR4-MM850 transceiver modules support
one-to-four splitting. 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.
NOTE:
•
As a best practice, use H3C transceiver modules and network cables for the switch.
•
The H3C transceiver modules and network cables are subject to change over time. For the most
recent list of H3C transceiver modules and cables, contact H3C Support or marketing staff.

For the specifications of H3C transceiver modules and network cables, see

QSFP28 port
The S6520X-30HC-EI, S6520X-54HC-EI, S6520X-30HC-HI, and S6520X-54HC-HI switches and
the LSWM2ZQP2P interface card provide QSFP28 ports. You can install QSFP+ modules and
cables in

, and
QSFP28 modules and cables in
in the QSFP28 ports as needed.
