Follow these steps to set up an IRF fabric:
Step Description
1. Plan IRF fabric setup
Plan the installation site and IRF fabric setup parameters. Complete the
following tasks:
• Planning IRF fabric size and the installation site
• Identifying the master switch and planning IRF member IDs
• Planning IRF topology and connections
• Identifying physical IRF ports on the member switches
• Planning the cabling scheme
2. Install IRF member
switches
See “Installing the switch in a 19-inch rack” or “Mounting the switch on a
workbench.”
3. Connect ground wires
and power cords
See “Grounding the switch” or “Connecting the power cord.”
4. Power on the switches

5. Configure basic IRF
settings
For more information about IRF, see the H3C S3100V2-52TP Switch IRF
Configuration Guide.
6. Connect the physical IRF
ports
Connect physical IRF ports on switches. Use Ethernet cables, SFP transceiver
modules, and fibers to connect ports over a long distance, or use SFP IRF
modules to connect ports over a short distance.
All switches except the master switch automatically reboot, and the IRF fabric
is established.
Planning IRF fabric setup
Planning IRF fabric size and the installation site
Choose S3100V2-52TP switch models and identify the number of required IRF member switches,
depending on the user density and upstream bandwidth requirements. The switching capacity of an IRF
fabric equals the total switching capacities of all member switches.
Plan the installation site depending on your network solution, as follows:
• Place all IRF member switches in one rack for centralized high-density access.
• Distribute the IRF member switches in different racks for dispersed access.
NOTE:
An IRF fabric can have up to nine S3100V2-52TP switches. As your business grows, you can plug an
S3100V2-52TP switch into an IRF fabric to increase the switchin
e
or replacement.
Identifying the master switch and planning IRF member IDs
Determine which switch you want to use as the master for managing all member switches in the IRF fabric.
An IRF fabric has only one master switch. You configure and manage all member switches in the IRF
fabric at the command line interface of the master switch.
