1.  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 scheme  
2.  Install IRF member 
switches 
See "Installing the switch in a 19-inch rack" a
nd "Mounting the switch on a 
workbench." 
3.  Connect the grounding 
cable, power supplies 
(optional), and power 
cords  
See "Grounding the switch" a
nd "Connecting the power cord." 
If an HP 5500-24G-SFP EI (2 slots) or 5500-24G-SFP EI TAA (2 slots) switch 
is used, also see "Installing/removing a power supply." 
4.  Power on the switches 
N/A 
5.  Install interface cards  
See "Installing/removing an interface card." 
6.  Configure basic IRF 
settings 
See "Configuring basic IRF settings." 
7.  Connect the physical IRF 
ports 
See "Connecting the physical IRF ports." 
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 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.  
 
  NOTE: 
any topology change 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. 
 
  NOTE: 
IRF member switches will automatically elect a master. You can affect the election result by assigning a 
high member priority to the intended master switch. For more information about master election, see
