Chapter 2 Using a Fabric Extender with a Cisco Nexus 7000 Series Switch
Cisco Nexus 2232TM FEX
Note To get the fully dedicated 10-Gbps bandwidth through a M1 Series 32-port 10-Gigabit Ethernet I/O
module, connect each FEX to one port in a set of four shared ports on the module (you connect each set
of shared ports to one FEX) and use the shared mode on the I/O module. If you are using the F2 Series
48-port 10-Gigabit Ethernet I/O module (N7K-F248XP-25) or the M2 Series 24-port 10-Gigabit
Ethernet I/O module (N7K-M224XP-23L), you can connect the FEX to any of its ports.
The Cisco Nexus 2232TM FEX also supports RJ-45 connectors for up to 32 downlink connections to
hosts. Table 2-2 lists the transceivers supported by this FEX for its uplink and downlink connections.
Figure 2-10 on page 2-10 shows the major features of the SFP+ optical transceiver used for uplink
connections.
Figure 2-11 on page 2-11 shows the major features of the SFP+ copper transceiver and cable used for
uplink connections.
Figure 2-12 on page 2-11 shows the major features of RJ-45 connectors, which are used for the downlink
connections.

1. The SFP-H10GB-CUxM transceivers are not supported by the M1 Series 32-port 10-Gigabit Ethernet I/O module (N7K-M132XP-12). These transceivers
are supported by the other Cisco Nexus 7000 Series I/O modules.
