Chapter 2 Installing the Cisco Nexus 5600 Series Switches
Installation Guidelines
• Have two people lift the switch. The Cisco Nexus 5672UP with two power supplies, weighs 32 lbs.
The Cisco Nexus 5672UP-16G with two power supplies, weighs 33 lbs. The Cisco Nexus 56128P
weighs 70 lbs. with 4 fans, 2 expansion modules and 4 power supplies. The Cisco Nexus 5696Q
weighs 134 lbs. with 4 fans, 2 generic expansion modules (GEMs), and 4 power supplies. The Cisco
Nexus 5624Q weighs 36 lbs. with two power supplies and 1 GEM. The Cisco Nexus 5648Q weighs
61.5 lbs. with two power supplies and 2 GEMs. Ensure that your footing is solid and the weight of
the switch is evenly distributed between your feet.
• Lift the switch 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 5600 switch, follow these guidelines:
• Record the information listed in Appendix G, “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 the service and airflow
requirements.
• Ensure that the air-conditioning meets the heat dissipation requirements listed in Appendix B,
“Technical Specifications,”
• 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 C-8.
• Ensure that the chassis can be 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
directly 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 5600 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 15-A or 20-A circuit.
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.
Note Ensure that all fan trays and power supplies have the same airflow direction.
