Cisco Nexus 2248TP-E
Supported Transceivers and Cables
The Cisco Nexus 2300 Series platform supports a wide variety of 1, 10, and 40 Gigabit Ethernet
connectivity options.
Caution
Currently, passive copper cables are not supported on the NIF/SIF ports. Also, 100M FX optics are not
supported.
For the most current list of supported transceivers and optics, refer to the latest Cisco Nexus 2000 Series
Fabric Extenders Release Notes at every release.
Cisco Nexus 2248TP-E
The Cisco Nexus 2248TP-E is a stackable 1 RU 17.2-inch (45 cm) deep FEX that supports 48 1000-TX
host-facing (downlink) ports and 4 10-Gigabit SFP+ network-facing (uplink) ports. You can order it with
port side exhaust or port side intake air cooling, and with AC or DC power supplies.
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 fan side.
You can order it with port-side exhaust or port-side intake air cooling, 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 air flow. 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.
Caution
Always make sure that all of the fan tray and power supply modules have the same direction of airflow
and the same color designation for that airflow direction. The switch does not support having more than
one direction of airflow with its modules.
