Cisco Nexus 2248TP-E
Ports
The Cisco Nexus 2248TP-E FEX supports a total of 48 100/1000BASE-T ports and four 10-Gigabit
Ethernet uplinks (SFP+). The Cisco Nexus 2300 series provides three types of ports: ports for end-host
attachment (host interfaces), uplink ports (fabric interfaces) and flexible ports (to be configured as either
host or fabric interfaces). Fabric interfaces are for connectivity to the upstream parent Cisco Nexus
switch and are indicated by yellow color. Flexible interfaces can be used for connectivity to the upstream
parent or towards the host, and are indicated by white color.
Power Supplies
The Cisco Nexus 2248TP-E 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 -3 lists the power supplies that you can order with the Cisco Nexus 2248TP-E FEX.
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.
Figure 1-14 shows an AC power supply with port-side exhaust airflow. Figure 1-15 shows an AC power
supply with port-side intake airflow. Figure1-16 shows a DC power supply with port-side exhaust
airflow. Figure1-17 shows a DC power supply with port-side intake airflow.
