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.
•
5G/2.5G/1000BASE-T autosensing Ethernet port—Category 5e or above twisted-pair cable.
•
2.5G/1000/100BASE-T autosensing Ethernet port—Category 5e 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 S5130S-EI Switch Series 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 S5130S-EI Switch Series Hardware Information
and Specifications.
If the IRF member switches are far away from one another, use transceiver modules and optical
fibers. If the IRF member switches are all in one equipment room, use twisted pair cables or
SFP/SFP+ cables.
As a best practice, use ring topology to connect the switches. The following describes cabling
schemes in ring topology.
Connecting the IRF member switches in one rack
Use SFP cables to connect the IRF member switches 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.

Restrictions for using the ports for
IRF connections
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.
The port must operate at 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.
