Chassis
The Cisco Nexus 2248PQ 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 17.5 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 of the switch ports at the rear of the chassis are in
close proximity to server ports, and all user-serviceable components are accessible from the fan side.
You can order port-side exhaust airflow or port-side intake airflow for cooling. 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.
Ports
The Cisco Nexus 2248PQ FEX supports a total of 48 1/10-Gigabit Ethernet/Fibre Channel over Ethernet
(FCoE) ports (SFP+) and 4 QSFP+ (16 10-Gigabit) fabric ports. The Cisco Nexus 2248PQ provides two
types of ports: ports for end-host attachments and uplink ports. Uplink ports are differentiated with
yellow for connectivity to the upstream parent Cisco Nexus 5000 Series switch.
The Cisco Nexus 2248PQ 10GE Fabric Extender supports FCoE and Data Center Bridging (DCB) which
increases the reliability, efficiency, and scalability of Ethernet networks by allowing the switches to
support multiple traffic classes over a lossless Ethernet fabric, enabling consolidation of LAN, SAN, and
cluster environments.
Power Supplies
The Cisco Nexus 2248PQ FEX chassis has two bays for fan side AC or DC power supplies. This chassis
is fully functional with one power supply, but you can install a second power supply for power
redundancy. The power supply is hot swappable during operations.
Table 1 -7 lists the power supplies that you can order with the Cisco Nexus 2248PQ FEX.
