Chapter 1 Using a Fabric Extender with a Cisco Nexus 5000 Series Switch
Cisco Nexus 2248TP-E
You can use this FEX with the Cisco Nexus 5000 Series switch. The Cisco Nexus 2248TP-E is managed
and configured by the upstream switch. The FEX software ships with the Cisco Nexus 5000 Series
switch software. The FEX downloads the software image from the switch the same way that a module
would download it from the supervisor in a modular chassis.

Chassis
The Cisco Nexus 2248TP-E 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 front panel.
You can order it with front-to-back or back-to-front air cooling, and with AC or DC power supplies. If
you are going to install the chassis with its front end facing the cold aisle, you must order the chassis
with front-to-back air flow. If you are going to install the chassis with its back end facing the cold aisle,
you must order the chassis with back-to-front airflow.
Figure 1-1 shows the location of the components found on the front of the chassis, and Figure 1-2 shows
the location of components found on the rear of the chassis. For information on what the chassis and
component LEDs indicate, see Table D-1 on page D-2.
