Transceivers and Connectors Supported by the Cisco Nexus 2232TM FEX
The Cisco Nexus 2232TM FEX supports SFP+ Ethernet optical and copper transceivers and optical FEX
Transceivers (FETs) for up to eight fabric uplink connections to the following Cisco Nexus 7000 Series
switch I/O modules:
• F2 Series 48-port 10-Gigabit I/O module (N7K-F248XP-25)
•
M1 Series 32-port, 10-Gigabit Ethernet I/O module (N7K-M132XP-12)
• M1 Series 32-port, 10-Gigabit Ethernet I/O module with XL option (N7K-M132XP-12L)
• M2 Series 24-port 10-Gigabit I/O module (N7K-M224XP-23L)
You must use the same transceivers on both ends of the same uplink cable.
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.
