Chassis
The Cisco Nexus 2248TP FEX chassis has a height of 1.72 inches (4.37 cm), a width of 17.3 inches
(43.94 cm), and a depth of 17.7 inches (44.96 cm). It weighs 17.7 pounds (8.0 kg). Its one-rack-unit (1
RU) form factor takes up relatively little space, making it easy to incorporate into rack designs. The FEX
is mounted in a standard 19-inch (48.26 cm) rack. All switch ports at the rear of the unit are in close
proximity to server ports, and all user-serviceable components are accessible from the fan side.
You can order it with port-side exhaust or port-side intake air cooling (do not mix air directions for a
chassis), and with AC or DC power supplies. If you are going to install the chassis with its fan side facing
the cold aisle, you must order the chassis with port-side exhaust airflow. If you are going to install the
chassis with its back end facing the cold aisle, you must order the chassis with port-side intake airflow.
Figure 1-21 shows the location of the components found on the fan side of the chassis, and Figure 1-22
shows the location of components found on the rear of the chassis. For information on what the chassis
and component LEDs indicate, see
Table E-1 on page E-2 .
