32Step Description1. Plan IRF fabric setup.Plan the installation site and IRF fabric setup parameters:• 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 scheme2. Install IRF memberswitches. See "Installing the switch in a 19-inch rack."3. Connect ground wiresand power cords. See "Grounding the switch" and "Connecting the power cord."4. Power on the switches. N/A5. Configure basic IRFsettings. See H3C S7500E-XS Switch Series IRF Configuration Guide.6. Connect the physicalIRF ports.Connect the physical IRF ports on switches. Use SFP+/QSFP+ transceivermodules and fibers for long-distance connection. Use twisted pair cables orSFP+/QSFP+ DAC cables for short-distance connection.All switches except the master switch automatically reboot, and the IRF fabric isestablished.Planning IRF fabric setupThis section describes issues that an IRF fabric setup plan must cover.Planning IRF fabric size and the installation siteChoose switch models and identify the number of required IRF member switches, depending on the userdensity and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the totalswitching 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 to implement the top-of-rack (ToR) accesssolution for a data center.As your business grows, you can add the switches into the IRF fabric to increase the switching capacitywithout any topology change or replacement.Identifying the master switch and planning IRF member IDsDetermine 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 IRFfabric at the command line interface of the master switch.
