or higher twisted pair cables, SFP+/QSFP+ cables, or SFP+/QSFP+ transceiver modules 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 Category 6 or
higher twisted pair/SFP+/QSFP+ cables. For more information about available SFP+/QSFP+ cables
and transceiver modules, see
The 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
same order as connected in the rack.
