IMPORTANT:
•
You can install a QSFP-40G-LR4-PSM1310 transceiver module on an S6520X-30QC-EI,
S6520X-54QC-EI, S6520X-30QC-HI, or S6520X-54QC-HI switch, or on a QSFP+ port on an
LSWM2QP2P interface module. You cannot use a QSFP-40G-LR4-PSM1310 transceiver
module to connect a QSFP+ port to four SFP+ ports.
•
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.
•
Only the S6520X-30HF-EI, S6520X-54HF-EI, S6520X-30HF-HI, and S6520X-54HF-HI switches
support the QSFP-40G-ER4-WDM1300 transceiver modules.
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, S6520X-54HC-HI, S6520X-30HF-EI,
S6520X-54HF-EI, S6520X-30HF-HI, and S6520X-54HF-HI switches and the LSWM2ZQP2P
interface module provide QSFP28 ports. You can install QSFP+ modules and cables in
, and
QSFP28 modules and cables in
and
QSFP28 ports as needed.
