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

Switch chassis Candidate physical IRF ports
S5830-52SC
• 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.
S5830-106S 10 fixed SFP+ ports on the front panel
Planning the cabling scheme
Use SFP+ cables or SFP+ transceivers 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 7 lists the SFP+ transceivers and SFP+ cables available for IRF connections.
