Planning the cabling scheme
Use the following cables to connect the IRF physical ports on the switch :
•
SFP+ transceiver modules and optical fiber or SFP+ cable
—SFP+ ports. For the available
models, see SFP+ port in " Appendix C Ports and LEDs ."
•
QSFP+ transceiver modules and optical fiber or QSFP+ cable
—QSFP+ ports. For the
available models, see QSFP+ port in " Appendix C Ports and LEDs ."
•
SFP28 transceiver modules and optical fiber or SFP28 cable
—SFP28 ports. For the
available models, see SFP28 port in " Appendix C Ports and LEDs ."
•
QSFP28 transceiver modules and optical fiber or QSFP28 cable
—QSFP28 ports. For the
available models, see QSFP28 port in " Appendix C Ports and LEDs ."
•
For the cables used for connecting 5G/2.5G/1000BASE-T and 10G/5G/2.5G/1000BASE-T
autosensing Ethernet ports, see "
Appendix C Ports and LEDs ."
For a short-distance IRF connection in an equipment room, use a twisted
pair/SFP+/QSFP+/SFP28/QSFP28 cable.
For a long-distance IRF connection, use SFP+/QSFP+/SFP28/QSFP28 transceiver modules and
optical fibers.
The following subsections describe several H3C recommended IRF connection schemes by using
SFP+ cables and SFP+ transceiver modules and fibers. All these schemes use a ring topology.
IMPORTANT:
In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on
different sides, you must measure the distance between them to select an appropriate cable.
