All the 10/100/1000BASE-T
autosensing Ethernet ports and
SFP ports on the front panel
The 52 GE 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 GE ports to an IRF port,
make sure the ports are in the same group.
GE ports in one group can be bound to
different IRF ports.
The ports must operate at 1 Gbps.
S5110V2-28P
S5110V2-28P-HPWR
The ports must operate at 1 Gbps.
Planning the cabling scheme
Use the following cables to connect the physical IRF ports on the switches:
•
10/100/1000BASE-T autosensing Ethernet ports
—Category 5 or above twisted pair cables.
•
SFP ports
—GE SFP transceiver modules and fibers or SFP cables. For the available SFP
transceiver modules and cables, see " Appendix C Ports and LEDs ."
If the IRF member switches are far away from one another, use SFP transceiver modules and optical
fibers. If the IRF member switches are all in one equipment room, use twisted pair cables or 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 Figure 16 . The switches
in the ring topology (see Figure 17 ) are in the same order as connected in the rack.
