Switch model Candidate physical IRF ports Requirements
A5500-48G-4SFP HI (2 slots)
• The two fixed SFP+ ports on the
front panel
• Ports on the 10GE XFP, SFP+,
CX4 interface cards on the rear
panel
• The SFP+ port numbered 53 on the
front panel and the physical ports on
interface card 2 must be bound to
the same IRF port.
• The SFP+ port numbered 54 on the
front panel and the ports on
interface card 1 must be bound to
the same IRF port.
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 SFP+ transceiver
modu
les/SFP+ cables,” “10 Gbps XFP transceiver modules,
” and “CX4 cables”.
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 differen
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 Figure 36. T
he switches in the ring topology (see Figure 37) are in the
same order as connected in the rack.
