Cisco Nexus 2248TP FEX
The Cisco Nexus 2248TP FEX is a stackable 1-RU FEX that has 48 100/1000 Ethernet host-facing
(downlink) ports and four 10-Gigabit Ethernet network-facing (uplink) ports. It requires a 19-inch (48.26
cm) rack for its installation. Table 2-3 lists its physical characteristics.
You can order the Cisco Nexus 2248TP 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.
Note For visual identification, back-to-front airflow fan trays and power supplies have a black stripe across
their front, and front-to-back airflow modules do not have a black stripe across their front. All of the
power supplies and fan trays must have the same direction of airflow for the components to properly
function (all of these components must either have a black stripe or all of the components must not have
a black stripe).
The front of the Cisco Nexus 2248TP FEX chassis has one or two power supplies, a fan tray, and two
chassis LEDs as shown in Figure 2-13. This FEX model requires one power supply, but if you want
power redundancy, you must install a second power supply.
