Figure 2-11 on page 2-10 identifies the major features of the SFP+ copper transceiver and cable used for
uplink connections. For the cable specifications that apply to these transceivers, see the “SFP+ Copper
Transceiver Specifications” section on page B-7.
Figure 2-12 on page 2-11 identifies the major features of RJ-45 connectors, which are used for the
downlink connections.
Cisco Nexus 2232TM FEX
The Cisco Nexus 2232TM FEX is a stackable, 1- and 10-Gigabit FEX that has 32 1- and 10-Gbps
Ethernet host-facing (downlink) 1/10GBASE-T ports and eight 10-Gbps Ethernet network-facing
(uplink) SFP+ ports. It requires a 19-inch (48.26 cm) rack for its installation. Table 2-7 lists its physical
characteristics.
You can order the Cisco Nexus 2232TM with front-to-back (port-side exhaust) or back-to-front
(port-side intake) airflow and with AC or DC power supplies. If you are going to install the port side in
a hot aisle, then order front-to-back airflow for the fan trays and power supplies. If you are going to
install the port side in the cold aisle, order back-to-front airflow for the fan trays and power supplies.
The front of the Cisco Nexus 2232TM FEX chassis has one or two power supplies, a fan tray, and two
LEDs as shown in Figure 2-16. This FEX model requires one power supply, but if you want power
redundancy, you must install a second power supply.
