Connecting the IRF member switches in a ToR solution
You can install IRF member switches in different racks side by side to deploy a top of rack (ToR)
solution.
Figure 41 shows an example for connecting four top of rack IRF member switches by using SFP
transceiver modules and optical fibers. The topology is the same as Figure 40.

Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see the fundamentals configuration guide for the switch series) to configure their member IDs,
member priorities, and IRF port bindings.
Follow these guidelines when you configure the switches:
Assign the master switch higher member priority than any other switch.
Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You
perform IRF port binding before or after connecting IRF physical ports depending on the
software release.
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see the IRF configuration guide or virtual
technologies configuration guide for the switch series, depending on the software version.
Connecting the IRF physical ports
Use twisted pair cables, SFP/SFP+ cables, or SFP/SFP+ transceiver modules and fibers to connect
the IRF member switches as planned.
Wear an ESD wrist strap when you connect twisted pair cables, SFP/SFP+ cables, or SFP/SFP+
transceiver modules and fibers. For how to connect them, see H3C Transceiver Modules User
Guide.
