“Transceivers and Connectors Supported by the Cisco Nexus 2248TP-E FEX” section on page3-8.
Power Supplies for the Cisco Nexus 2248TP-E FEX
The Cisco Nexus 2200 Series FEX chassis have two slots for front-end AC or DC power supplies that
have port-side-exhaust or port-side-intake airflow. These chassis are fully functional with one power
supply, but you can install a second power supply for power redundancy. If you have only one power
supply in the chassis, install a blank filler panel (N2200-P-BLNK) to maintain the designed airflow in
the chassis. You can install any of the following power supplies in those two bays:
•AC power supply with port-side-exhaust airflow (N2200-PAC-400W)
•AC power supply with port-side-intake airflow (N2200-PAC-400W-B)
•DC power supply with port-side-exhaust airflow (N2200-PDC-400W)
•DC power supply with port-side-intake airflow (N2200-PDC-350W-B)
Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the
same color designation on the front. Otherwise, the switch can over heat and shut down,
Figure 3-4 shows the exterior components on an AC power supply with port-side-exhaust airflow (no
black stripe on the front). Figure 3-5 shows the components on a DC power supply with
port-side-exhaust airflow. Figure3-6 shows the black stripe used to indicate port-side-intake airflow (in
this case on an AC power supply). Figure3-7 shows the blank filler panel that you should install in an
open power supply slot if the chassis has only one power supply.
