IMPORTANT:
•
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 switch do not support the LSTM1STK cable.
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.
•

SFP28 port
An LSWM2ZSP8P interface card 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
Table 8-6 and SFP28
cables in Table 8-7 in the SFP28 ports.
