and fibers
If the IRF member switches are far
away from one another, choose the
SFP+/QSFP+ transceiver modules with
optical fibers.
If the IRF member switches are all in
one equipment room, choose twisted
pair/SFP+/QSFP+ network cables.
For more information about available
SFP+/QSFP+ network cables and
transceiver modules, see SFP+ port on
page 61 and
QSFP+ port on page
64.

Review the following IRF connection schemes recommended by Hewlett Packard Enterprise. These schemes use a ring
topology.
• Connecting the IRF member switches in one rack on page 41
• Connecting the IRF member switches in a ToR solution on page 42
Connecting the IRF member switches in one rack
Procedure
Use SFP+ network cables to connect the IRF member switches (four switches in this example) in a rack as shown in Figure 31:
Connecting the switches in one rack on page 41. The switches in the ring topology (as shown in Figure 32: IRF fabric
topology on page 42) are in the same order as connected in the rack.
