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 port-side exhaust or 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 port-side exhaust
airflow for all of the fan trays and power supplies. If you are going to install the port side in the cold
aisle, order port-side intake airflow for all of the fan trays and power supplies.
