Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection

scheme.

Table 8

shows the physical ports that can be used for IRF connection.

Use SFP+ cables or SFP+ transceiver modules and fibers to connect the IRF member switches. If the

IRF member switches are far away from one another, choose the SFP+ transceiver modules with

optical fibers. If the IRF member switches are all in one equipment room, choose SFP+ cables.

Table 21

and

The following subsections describe several HP recommended IRF connection schemes. 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.

Candidate physical IRF ports

•

2 fixed SFP+ ports on the front panel

•

2 SFP+ ports on the 10 GE SFP+ expansion interface card at the rear

panel

NOTE:

You must purchase the expansion interface card separately.
