Planning the cabling scheme
The IRF physical ports on the switch use the following transceiver modules and cables for
connection:
•
SFP+ port —SFP+ transceiver module and optical fiber or SFP+ cable.
•
QSFP+ port —QSFP+ transceiver module and optical fiber or QSFP+ cable.
•
SFP28 port —SFP28 transceiver module and optical fiber or SFP28 cable.
•
5G/2.5G/1000BASE-T autosensing Ethernet port —Twisted pair cable.
•
10G/5G/2.5G/1000BASE-T autosensing Ethernet port —Twisted pair cable.
For the available transceiver module and cable types, see ports in Hardware Information and
Specifications .
For a short-distance IRF connection in an equipment room, use a twisted pair/SFP+/QSFP+/SFP28
cable. For a long-distance IRF connection, use SFP+/QSFP+/SFP28 transceiver modules and
optical fibers.
The following subsections describe several H3C recommended IRF connection schemes by using
SFP+ cables and SFP+ transceiver modules and fibers. 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
Connect the IRF member switches (9 switches in this example) in a rack as shown in Figure4-4 . The
switches in the ring topology (see Figure4-5 ) are in the same order as connected in the rack.
