Planning the cabling scheme
Use the following cables to connect the IRF physical ports on the switch :
•
5G/2.5G/1000BASE-T and 10G/5G/2.5G/1000BASE-T autosensing Ethernet ports—For
the available cables, see ports in Hardware Information and Specifications.
•
SFP+ ports—SFP+ transceiver modules and optical fibers or SFP+ cables. For the available
models, see ports in Hardware Information and Specifications.
•
QSFP+ ports—QSFP+ transceiver modules and optical fibers or QSFP+ cables. For the
available models, see ports in Hardware Information and Specifications.
•
SFP28 ports—SFP28 transceiver modules and optical fibers or SFP28 cables. For the
available models, see ports in Hardware Information and Specifications.
•
QSFP28 ports—QSFP28 transceiver modules and optical fibers or QSFP28 cables. For the
available models, see ports in Hardware Information and Specifications.
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.
