Power Supply
The Cisco Nexus 5020 switch uses a front-end power supply. 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 1-13 shows the power supply, which has two LEDs: one for
power status and one for failure condition.
