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

" 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 S5800 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 S5800 switches. As your business grows, you can plug an S5800 switch
into an IRF fabric to increase the switching capacity without any topology change or replacement.
