Removing a Power Supply
Caution If you are using a Cisco Nexus 5500 Platform switch or a Cisco Nexus 5000 Platform switch with one
power supply, removing the power supply causes the switch to shut down. If you are using two power
supplies and you remove one of them, the switch can continue to operate.
To remove an AC or DC power supply, follow these steps:
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection instructions,
see the “Grounding the Switch” section on page 2-17.
Step 2 Remove the AC power cord or DC wiring connector.
Step 3 Grasp the power supply handle with your left hand.
Step 4 Push against the release latch with your left thumb, and slide the power supply part way out of the
chassis. To remove a power supply from a Cisco Nexus 5500 Platform chassis, see Figure 4-8 and
Figure 4-9. To remove a power supply from the Cisco Nexus 5020 switch, see Figure 4-10. To remove a
power supply from the Cisco Nexus 5010 switch, see Figure 4-11.
