Power Supplies
The Cisco Nexus 2232TM-10GE FEX chassis has two bays for front-end 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 1-14 lists the power supplies that you can order with the Cisco Nexus 2232TM-10GE FEX.
Figure 1-12 on page 1-12 shows an AC power supply with front-to-back airflow. Figure 1-13 on
page 1-13 shows an AC power supply with back-to-front airflow. Figure 1-14 on page 1-13 shows a DC
power supply with front-to-back airflow.
You can order the Cisco Nexus 2232TM-10GE FEX with AC power supplies that have front-to-back or
back-to-front airflow for cooling or DC power supplies that have front-to-back airflow. The
back-to-front airflow components have a black stripe on their front surface for easy visual identification.
The front-to-back airflow components do not have a black stripe.
Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow
direction and that the air intake for those modules is positioned on a cool aisle. If you install a module
that uses a different direction of airflow from the other modules in your system, you will see an error
message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can
reach an overtemperature state and shut down.
If one power supply is installed in the chassis, but the other power supply slot is empty, you should use
a blank filler panel (N2200-P-BLNK) to cover the empty slot. Figure 1-15 on page 1-14 shows a blank
power supply filler panel.
