Planning the cabling scheme
Use CX4/SFP+ cables or SFP+/XFP transceiver modules and fibers to connect the IRF member switches.
If the IRF member switches are far away from one another, choose the SFP+ or XFP transceiver modules
with optical fibers. If the IRF member switches are all in one equipment room, choose CX4 or SFP+
cables.
For the transceiver modules and cables available for IRF connections, see "
10 Gbps XFP transceiver modules
," and "
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 CX4/SFP+ cables to connect the IRF member switches (nine switches in this
example) in a rack as shown in
. The switches in the ring topology (see
) are in the
same order as connected in the rack.
