Power Supply

The Cisco Nexus 5020 switch uses a front-end power supply with front to back airflow. The chassis has slots for two power supplies. Two power supplies can be used for redundancy, but the Cisco Nexus 5020 switch is fully functional with one power supply. Figure 1-39shows the power supply, which has two LEDs: one for the power status and one for the failure condition.

For descriptions of the LEDs, see Table D-1 on page D-2. For descriptions of power supply conditions indicated by the LEDs, see Table D-2 on page D-3.

If you have one power supply installed in the chassis, but the other power supply slot is empty, you should use a power supply blank panel to cover the empty slot. Figure 1-40shows a blank power supply panel.
