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
•
2.
Install IRF member switches
Installing the switch in a 19-inch rack
3.
Connect ground wires and power cords See "
" and "
."
4.
Power on the switches
N/A
5.
Configure basic IRF settings
For more information about IRF, see H3C S5820X & S5800
Switch Series IRF Configuration Guide.
6.
Connect the physical IRF ports
Connect 10GE physical IRF ports on switches. Use SFP+
transceiver modules and fibers to connect 10-Gigabit SFP+
ports over a long distance, or use SFP+ cables to connect
10-Gigabit SFP+ ports over a short distance.
Use category 6 or above twisted pair cables to connect
1/10Gbase-T Ethernet 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 S5820X 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 to implement the top-of-rack (ToR) access
solution for a data center.
NOTE:
An IRF fabric can have up to 10 S5820X switches. As your business grows, you can plug an S5820X
switch into an IRF fabric to increase the switching capacity without any topology change or replacement.
