The following subsections describe several HP recommended IRF connection schemes, and all these
schemes use a ring topology.
IMPORTANT:
In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different
sides, you must measure the distance between them to select an appropriate cable.
Connecting the IRF member switches in one rack
Use short-haul and long-haul SFP+ cables to connect the IRF member switches (10 switches in this
example) in a rack as shown in
same order as connected in the rack.
