Identifying Physical Irf Ports On The Member Switches; Planning The Cabling Scheme - HP FlexNetwork 5120 SI Series Installation Manual

Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection
scheme.
All network ports can be used for IRF connection. As a best practice, use Gigabit SFP ports and HPE
3600 Switch SFP Stacking Kit cables for IRF connection.

Planning the cabling scheme

You can use the GE twisted pair cables, SFP transceiver modules and optical fibers, or SFP Stacking
Kit cables to connect the 5120 SI switches for IRF connections. As a best practice, use Gigabit SFP
ports and HPE 3600 Switch SFP Stacking Kit cables for IRF connection.
Figure 25 shows two IRF connection schemes and uses Gigabit SFP ports and HPE 3600 Switch
SFP Stacking Kit cables for IRF connection. All these schemes use a ring topology.
Figure 26 shows the IRF fabric topology.
