Planning the cabling scheme
Use twisted pair cables, SFP+/QSFP+ network cables, or SFP+ transceiver modules and fibers to
connect the IRF member switches. If the IRF member switches are far away from one another,
choose the SFP+ transceiver modules with optical fibers. If the IRF member switches are all in one
equipment room, choose twisted pair cables or SFP+/QSFP+ network cables. For more information
about SFP+/QSFP+ network cables and SFP+ transceiver modules, see
LEDs."
The following subsections describe several H3C recommended IRF connection schemes, and 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.
Connecting the IRF member switches in one rack
Use SFP+ network cables to connect the IRF member switches (9 switches in this example) in a rack
as shown in
connected in the rack.
Candidate physical IRF ports
•
Four fixed SFP+ ports on the front panel

Two fixed QSFP+ ports on the rear panel
Four fixed SFP+ ports and two fixed QSFP+
ports on the front panel

Requirements
•
All physical ports to be bound
to an IRF port must use the
same port rate.
•
For the S5130-54QS-HI
switch, SFP+ ports 49 to 52
form a group. When an SFP+
port is bound to an IRF port,
other SFP+ ports in the same
port group cannot be used as
service ports, and vice versa.
Each QSFP+ port is a group.
•
For other models, physical
ports on different expansion
cards can be bound to the
same IRF port.
