IMPORTANT:
The S6520X-18C-SI and S6520X-26C-SI switches must use PSR150-A1 or PSR150-D1 power
modules for power supply when the switches are installed with SFP-XG-LH80-SM1550 transceiver
modules.
NOTE:
• As a best practice, use H3C SFP/SFP+ transceiver modules and cables for the SFP+ ports on
the switch.
• The H3C SFP/SFP+ transceiver modules and cables available for the SFP+ ports on the switch
are subject to change over time. For the most recent list of SFP/SFP+ transceiver modules and
cables available for the SFP+ ports, contact your H3C Support or marketing staff.
• For more information about H3C SFP/SFP+ transceiver modules and cables, see H3C
Transceiver Modules User Guide.

SFP28 port

The LSWM2ZSP2PM interface card provides the fixed 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 25G SFP28 transceiver modules in
