Cisco Nexus 2248TP FEX
You can order the Cisco Nexus 2248TP FEX 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 port-side-exhaust airflow for 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-intake airflow fan trays and power supplies have a black stripe across
their front, and port-side-exhaust 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 Figure3-13. This FEX model requires one power supply, but if you want
power redundancy, you must install a second power supply.
