Cisco Nexus 2248TP-E FEX
The Cisco Nexus 2248TP-E FEX (N2K-C2248TP-E) 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 -1 lists its physical characteristics.
You can order the Cisco Nexus 2248TP-E with port-side exhaust or back-to-front 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 the fan trays and power supplies.
Note For visual identification, port-side exhaust airflow power supplies and fan trays have a black stripe
across their front, and port-side intake 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-E FEX chassis has one or two power supplies, a fan tray, and two
chassis LEDs as shown in Figure2-1. This FEX model requires one power supply, but if you want power
redundancy, you must install a second power supply.
