Planning the cabling scheme

Use the following cables to connect the IRF physical ports on the switches:
•
10/100/1000BASE-T autosensing Ethernet port—Category 5 or above twisted-pair cable.
•
10/5/2.5/1GBASE-T autosensing Ethernet port—Category 6 or above twisted-pair cable.
•
SFP port—GE SFP fiber transceiver module and optical fiber, GE SFP copper transceiver
module and twisted pair cable or GE SFP cable. For the available transceiver models and
cables, see ports in Hardware Information and Specifications.
•
SFP+ port—SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available
transceiver models and cables, see ports in Hardware Information and Specifications.
If the IRF member switches are far away from one another, use SFP/SFP+ transceiver modules and
optical fibers. If the IRF member switches are all in one equipment room, use twisted pair cables or
SFP/SFP+ cables.

Restrictions for using the ports for
IRF connections
All physical ports to be bound to an IRF port
must have the same data rate.
The port must operate at its highest speed.
•
SFP+ port—10 Gbps
•
10/100/1000BASE-T autosensing
port—1 Gbps
•
SFP port—1 Gbps
For a 52-port switch model, the 52 ports are
divided into two groups: ports 1 to 24, port 51,
and port 52 in one group and ports 25 to 50 in
the other group.
To bind multiple ports to an IRF port, make
sure the ports are in the same group. Ports in
one group can be bound to different IRF ports.
All physical ports to be bound to an IRF port
must have the same data rate.
The port must operate at its highest speed.
•
10/5/2.5/1GBASE-T autosensing
