NOTE:
•
As a best practice, use H3C transceiver modules and cables for the switch.
•
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.
•
The H3C transceiver modules and cables are subject to change over time. For the most recent
list of H3C transceiver modules and cables, contact your H3C Support or marketing staff.

Combo interface
The S5560X-30C-EI and S5560X-30F-EI switches each provide eight combo interfaces. The
S5560X-34S-EI switch provides four 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.
