NOTE:
•
As a best practice, use H3C QSFP+ transceiver modules, QSFP+ cables, or QSFP+ to SFP+ cables for the
QSFP+ ports on the switch. The H3C QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to SFP+
cables available for the QSFP+ ports are subject to change over time. For the most recent list of QSFP+
transceiver modules, QSFP+ cables, and QSFP+ to SFP+ cables available for the QSFP+ ports, contact
H3C Support or marketing staff.
•
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.
For more information about H3C QSFP+ transceiver modules, QSFP+ cables, and QSFP+ to SFP+ cables,
see
H3C Transceiver Modules User Guide

Combo interface
The S5560-30F-EI and S5560-34C-EI switches each provide eight combo interfaces. A combo interface
contains an SFP port and a 10/100/1000BASE-T autosensing Ethernet port. Only one of these two ports
can operate at a time.
