transceiver modules with optical fibers. If the IRF member switches are all in one equipment room, choose
twisted pair/SFP+/QSFP+ cables. For more information about available SFP+/QSFP+ cables and
transceiver modules, see "SFP+ port" and "QSFP+ port."
T
he following subsections describe several HP recommended IRF connection schemes, and all these
schemes use a ring topology.
Connecting the IRF member switches in one rack
Use short-haul and long-haul SFP+ cables to connect the IRF member switches (four switches in this
example) in a rack as shown in Figure 47. T
he switches in the ring topology (as shown in Figure 48) are
in the same order as connected in the rack.

Connecting the IRF member switches in a ToR solution
You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.
Figure 49 sho
ws an example for connecting four top of rack IRF member switches by using SFP+/QSFP+
cables, and SFP+/QSFP+ transceiver modules, and optical fibers. The topology is the same as Figure
48.
