Cisco Nexus 5000 Platform Switches
Power Supply
The Cisco Nexus 5020 switch uses a front-end power supply with front-to-back (port-side exhaust)
airflow. The chassis has slots for two power supplies. Two power supplies can be used for redundancy,
but the Cisco MDS 9200 Series is fully functional with one power supply. Figure 1-39 shows 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 1-40 shows a blank power supply
panel.
