Ports 1 to 8 on the S6520X-54HC-EI and S6520X-54HC-HI switches do not support GE SFP
transceiver modules or cables.
The SFP+ ports on the S6520X-54QC-EI and S6520X-54QC-HI switches do not support the
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.

SFP28 port
The LSWM2ZSP8P and LSWM2ZSP2P interface modules provides SFP28 ports. To connect peer
SFP28 ports over a long distance, use SFP28 transceiver modules and fibers. To connect peer
SFP28 ports over a short distance, use SFP28 cables. You can install SFP28 transceiver modules in
Table4-7 and SFP28 cables in Table4-8 in the SFP28 ports.
