Chapter2 Using a Fabric Extender with a Cisco Nexus 7000 Series Switch
Cisco Nexus 2232PP FEX
Fan Tray for the Cisco Nexus 2232PP FEX
The Cisco Nexus 2232PP and 2232TM FEX use the same fan tray, which you can order with either
port-side exhaust airflow (N2K-C2232-FAN) or port-side intake airflow (N2K-C2232-FAN-B).
Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the
same color designation on the front. Otherwise, the switch can over heat and shut down,
For more information on this fan tray, see the “Fan Tray for the Cisco Nexus 2232TM FEX” section on
page 2-19 and the fan tray specifications in AppendixB, “Technical Specifications”. For LED
descriptions, see Appendix E, “LEDs”.
Transceivers Supported by the Cisco Nexus 2232PP FEX
The Cisco Nexus 2232PP 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.
