Record the information listed in
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,"
requirements).
Ensure that the air-conditioning meets the heat dissipation requirements listed in
"Technical Specifications."
Ensure that the cabinet or rack meets the requirements listed in
Installation."
Jumper power cords are available for use in a cabinet. See the
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
Specifications." If available, you can use an uninterruptible power supply (UPS) to protect against
power failures.
Avoid UPS types that use ferroresonant technology. These UPS types can become unstable
with systems such as the Cisco Nexus 6000 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.
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.
Ensure that all fan trays and power supplies have the same airflow drection.
Use the following screw torques when installing the switch:
Captive screws: 4 in-lb (0.45 N
–
M3 screws: 4 in-lb (0.45 N
–
M4 screws: 12 in-lb (1.36 N
–
10-32 screws: 20 in-lb (2.26 N
–
12-24 screws: 30 in-lb (3.39 N
