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. Use SFP+ transceiver modules and optical fibers rather than twisted pair cables or SFP+
DAC cables to connect the switches over a long distance.
shows an example for connecting 9 top of rack IRF member switches. The topology is the

Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see
H3C S5130-EI Switch Series Fundamentals Configuration Guide
) 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
H3C S5130-EI Switch Series IRF
Configuration Guide

Connecting the physical IRF ports
Use twisted pair cables, SFP+ DAC cables, or 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+ DAC cables, or SFP+
transceiver modules and fibers. For how to connect them, see
H3C Transceiver Modules and
Network Cables Installation Guide
