•Disconnect all power and external cables before lifting the system.
•Have two people to lift the system. The Nexus 5020 weighs 50 lb (22.680 kg) and the Nexus 5010 weighs 35 lb.
•Ensure that your footing is solid and the weight of the system is evenly distributed between your feet.
•Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.
Installation Guidelines
When installing the Cisco Nexus 5000 switch, follow these guidelines:
•Plan your site configuration and prepare the site before installing the chassis. Appendix D, “Site Planning and Maintenance Records,” lists the recommended site planning tasks.
•Record the information listed in Appendix D, “Site Planning and Maintenance Records,” as you install and configure the switch.
•Ensure that there is adequate space around the switch to allow for servicing the switch and for adequate airflow (Appendix B, “Technical Specifications,” lists airflow requirements).
•Ensure that the
•Ensure that the cabinet or rack meets the requirements listed in Appendix A, “Cabinet and Rack Installation.”
Note Jumper power cords are available for use in a cabinet. See the “Jumper Power Cord” section on page
•Ensure that the chassis is adequately grounded. If the switch is not mounted in a grounded rack, we recommend connecting both the system ground on the chassis and the power supply ground to an earth ground.
•Ensure that the site power meets the power requirements listed in Appendix B, “Technical Specifications.” If available, you can use an uninterruptible power supply (UPS) to protect against power failures.
Caution Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco Nexus 5000 switch, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.
•Ensure that circuits are sized according to local and national codes. For North America, the power supply requires a
Caution To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the switch are within the current ratings for the wiring and breakers.
